Unable to resolve "unable to get local issuer certificate" using git on Windows with self-signed certificate

windows git curl ssl-certificate msysgit

I am using Git on Windows. I installed the msysGit package. My test repository has a self signed certificate at the server. I can access and use the repository using HTTP without problems. Moving to HTTPS gives the error:

SSL Certificate problem: unable to get local issuer certificate.

I have the self signed certificate installed in the Trusted Root Certification Authorities of my Windows 7 - client machine. I can browse to the HTTPS repository URL in Internet Explorer with no error messages.

This blog post by Philip Kelley explained that cURL does not use the client machine's certificate store. I followed the blog post's advice to create a private copy of curl-ca-bundle.crt and configure Git to use it. I am sure Git is using my copy. If I rename the copy; Git complains the file is missing.

I pasted in my certificate, as mentioned in the blog post, I still get the message "unable to get local issuer certificate".

I verified that Git was still working by cloning a GitHub Repository via HTTPS.

The only thing I see that's different to the blog post is that my certificate is the root - there is no chain to reach it. My certificate originally came from clicking the IIS8 IIS Manager link 'Create Self Signed Certificate'. Maybe that makes a certificate different in some way to what cURL expects.

How can I get Git/cURL to accept the self signed certificate?

Possible duplicate of configure Git to accept a particular self-signed server certificate for a particular https remote

Also check whether your local network is permitted to push files to github repository. There may be some firewall or antivirus restriction.

If anyone faces this error while using Bower, create a .bowerrc file with content { "strict-ssl": false }. Don't thank me, thank this guy: stapp.space/fight-with-2 I've fought with this error for close to 5 hours, straight!!

Might help someone: I am using gitlab and I face this error if I clone via https. But if I use ssh then it works perfectly fine.

I get the best solution here. stackoverflow.com/questions/24611640/…

The problem is that git by default using the "Linux" crypto backend.

Beginning with Git for Windows 2.14, you can now configure Git to use SChannel, the built-in Windows networking layer as the crypto backend. This means that it will use the Windows certificate storage mechanism and you do not need to explicitly configure the curl CA storage mechanism: https://msdn.microsoft.com/en-us/library/windows/desktop/aa380123(v=vs.85).aspx

Just execute:

git config --global http.sslbackend schannel

That should help.

Using schannel is by now the standard setting when installing git for Windows, also it is recommended to not checkout repositories by SSH anmore if possible, as https is easier to configure and less likely to be blocked by a firewall it means less chance of failure.

Note however that this solution can make git config --global http.sslCAInfo <my-server-self-signed-cert.pem> fail to work. I configured http.sslCAInfo to use a self-signed certificate for my server, and it's the reason (may not be same as OP) that I encountered "SSL Certificate problem: unable to get local issuer certificate" when I do e.g. a git clone https://github.com/Microsoft/vscode.git. Finally I used the answer from stackoverflow.com/a/47196562/1323552 (Ben P.P. Tung) to tune my sslCAInfo config specific to my git server to solve it.

Worked for me, I thought for sure i'd have to configure a proxy as I'm behind a corporate FW, but nope, one command and my clone worked (and SSL is enabled)! +1

If you are looking way to include a certificate for on-premise github server into the git certstore, follow this solution.

This one worked for me, I'm using VS code, company has some VPN software installed guarding the traffic, this solution resolve my issue. Thanks.

Open Git Bash and run the command if you want to completely disable SSL verification.

git config --global http.sslVerify false

Note: This solution opens you to attacks like man-in-the-middle attacks. Therefore turn on verification again as soon as possible:

git config --global http.sslVerify true

This answer defeats the security of SSL by permitting man-in-the-middle attacks. Other answers already explain how to configure git to trust the specific certificate you need.

horrible answer indeed, you don't even tell them to turn SSL back on. This is why security vulnerabilities happen.

To disable TLS/SSL verification for a single git command, use the following command: git -c http.sslVerify=false clone https://domain.com/path/to/git

There are several solutions already provided below, and I have already suggested the cons. So it's up to you that what solutions you are are picking to resolve the issue.

This can be a workarround, but never a solution. Also, it is better do not bypass all ssl verification. You can use git config --local http.sslVerify false. In this way only one repository is insecure

I had this issue as well. In my case, I was trying to get a post-receive Git hook to update a working copy on a server with each push. Tried to follow the instructions in the blog you linked to. Didn't work for me as well and overriding the settings on a per-user basis didn't seem to work either.

What I ended up having to do was disable SSL verification (as the article mentions) for Git as a whole. Not the perfect solution, but it'll work until I can figure out a better one.

I edited the Git config text file (with my favorite line-ending neutral app like Notepad++) located at:

C:\Program Files (x86)\Git\etc\gitconfig

In the [http] block, I added an option to disable sslVerify. It looked like this when I was done:

[http]
    sslVerify = false
    sslCAinfo = /bin/curl-ca-bundle.crt

That did the trick.

NOTE:

This disables SSL verification and is not recommended as a long term solution.

You can disable this per-repository which still isn't great, but localizes the setting.

With the advent of LetsEncrypt.org, it is now fairly simple, automated and free to set up SSL as an alternative to self-signed certs and negates the need to turn off sslVerify.

This defeats the purpose of SSL.

you can use the command "git config --global http.sslVerify false" to disable SSL verification

Thanks for pointing the sslCAinfo configuration entry out; but I'm not upvoting the answer since it doesn't make much sense to permanently disable SSL for git system-wide (have you tried to disable it system-wide, then clone, then re-enable it and then disable it in the local git config for the newly cloned repo?).

For a one-off command, there is no need to change config files: git -c http.sslVerify=false clone https://...

Better fix here: blogs.msdn.microsoft.com/phkelley/2014/01/20/…

Vimes

kiddailey I think was pretty close, however I would not disable ssl verification but rather rather just supply the local certificate:

In the Git config file

[http]
    sslCAinfo = /bin/curl-ca-bundle.crt

Or via command line:

git config --global http.sslCAinfo /bin/curl-ca-bundle.crt

On git for windows, this is git config --global http.sslCAinfo /usr/ssl/certs/ca-bundle.crt

Or for me git config --global http.sslCAinfo /c/Program\ Files\ $x86$/Git/bin/curl-ca-bundle.crt

For users on MacPorts, this is git config --global http.sslCAinfo /opt/local/share/curl/curl-ca-bundle.crt

With Git 2.8 you can use git config --list --show-origin to see where the http.sslCAinfo config is set

My certificate location on mac is : ~/macports/share/curl/curl-ca-bundle.crt

Franklin Yu

I faced this issue as well. And finally got resolved by getting guidance from this MSDN Blog.

Update

Actually you need to add the certificate in git's certificates file curl-ca-bundel.cert that resides in Git\bin directory.

Steps

Open your github page in browser, and click over lock icon in address bar. In the opened little popup up navigate to 'view certificate' link, it will open a popup window. In which navigate to certificates tab (3rd in my case). Select the top node that is root certificate. And press copy certificate button in the bottom and save the file. In file explorer navigate Git\bin directory and open curl-ca-bundle.crt in text editor. Open the exported certificate file (in step 3) in text editor as well. Copy all of the content from exported certificate to the end of curl-ca-bundle.crt, and save.

Finally check the status. Please note that backup curl-ca-bundle.crt file before editing to remain on safe side.

"navigate Git\bin directory and open curl-ca-bundle.crt" There is not curl-ca-bundle.crt in the git\bin!

@AntonK if it doesn't exist, create one yourself in notepad, and rename it with curl-ca-bundle.crt. Other steps remain same.

@AntonK It may be called just ca-bundle.crt and be located in mingw64\ssl\certs or mingw32\ssl\certs.

Used this for Atlassian's SourceTree. The bundled GIT installation is in %userprofile%\appdata\local\attlassian\sourcetree\git_local. curl-ca-bundle.crt already existed, appended my base64 encoded exported root cert.

One problem with this answer. When you update git it restores the ca-bundle.crt file to it's original state (i.e. you loose your self signed public cert)

isherwood

An answer to Using makecert for Development SSL fixed this for me.

I do not know why, but the certificate created by the simple 'Create Self Signed Certificate' link in IIS Manager does not do the trick. I followed the approach in the linked question of creating and installing a self-signed CA Root; then using that to issue a Server Authentication Certificate for my server. I installed both of them in IIS.

That gets my situation the same as the blog post referenced in the original question. Once the root certificate was copy/pasted into curl-ca-bundle.crt the git/curl combo were satisfied.

"I do not know why, but the certificate created by the simple 'Create Self Signed Certificate' link in IIS Manager does not do the trick..." - The best I can tell, it creates malformed certificates. There's lots of rules when creating X.509 certificates; the "do the minimum to make it work" no longer works well. Also see How do you sign Certificate Signing Request with your Certification Authority and How to create a self-signed certificate with openssl?

This worked for me, but I got temporarily hung up on the "I installed both of them in IIS" part. To clairfy for others...the server cert is assigned in IIS, and the root CA needs to be imported to "Trusted Root Certification Authorities” via the Windows cert manager utility (certmgr.msc)

zionyx

To avoid disabling ssl verification entirely or duplicating / hacking the bundled CA certificate file used by git, you can export the host's certificate chain into a file, and make git use it:

git config --global http.https://the.host.com/.sslCAInfo c:/users/me/the.host.com.cer

If that does not work, you can disable ssl verification only for the host:

git config --global http.https://the.host.com/.sslVerify false

Note : Subjected to possible man in the middle attacks when ssl verification is turned off.

It may be worth noting that the --global option is not necessary: if you omit --global, the setting only applies to that particular git repo.

How about if its my enterprise github? How do I obtain the root and intermediate CA is .cer format. I could only get .p7b files.

Jawad Al Shaikh

In case of github Repositories (or any none-self-signed certs), choosing below while installing Git-on-windows, resolved the issue.

https://i.stack.imgur.com/zn1Uk.png

You seemed to have answered a different question. The OP's question concerned self-signed certificates on Windows clients.

@jww the question title is a git error message that's shown even if repo is NOT self-signed SSL!

This got me passed the error, but for me accessing GitHub Enterprise required some key generation and adding of public/private keys.

If the self signed certifcate has been put into the windows certificates store by a helpful windows admin via a group policy then this answer is also a good one.

phifi

To completely detail out the summary of all the above answers.

Reason

This problem is occuring because git cannot complete the https handshake with the git server were the repository you are trying to access is present.

Solution

Steps to get the certificate from the github server

Open the github you are trying to access in the browser Press on the lock icon in the address bar > click on 'certificate' Go to 'Certification Path' tab > select the top most node in the hierarchy of certificates > click on 'view certificate' Now click on 'Details' and click on 'Copy to File..' > Click 'Next' > Select 'Base 64 encoded X509 (.CER)' > save it to any of your desired path.

Steps to add the certificate to local git certificate store

Now open the certificate you saved in the notepad and copy the content along with --Begin Certificate-- and --end certificate-- To find the path were all the certificates are stored for your git, execute the following command in cmd. git config --list Check for the key 'http.sslcainfo', the corresponding value will be path.

Note: If u can't find the key http.sslcainfo check for Git's default path: C:\Program Files\Git\mingw64\ssl\certs

Now open 'ca-bundle.crt' present in that path.

Note 1 : open this file administrator mode otherwise you will not be able to save it after update. (Tip - you can use Notepad++ for this purpose) Note 2 : Before modifying this file please keep a backup elsewhere.

Now copy the contents of file mentioned in step 1 to the file in step 4 at end file, like how other certificates are placed in ca-bundle.crt. Now open a new terminal and now you should be able to perform operations related to the git server using https.

I followed the steps but that didn't worked for me

I've just had the same issue but using sourcetree on windows Same steps for normal GIT on Windows as well. Following the following steps I was able to solve this issue.

Obtain the server certificate tree This can be done using chrome. Navigate to be server address. Click on the padlock icon and view the certificates. Export all of the certificate chain as base64 encoded files (PEM) format. Add the certificates to the trust chain of your GIT trust config file Run "git config --list". find the "http.sslcainfo" configuration this shows where the certificate trust file is located. Copy all the certificates into the trust chain file including the "- -BEGIN- -" and the "- -END- -". Make sure you add the entire certificate Chain to the certificates file

This should solve your issue with the self-signed certificates and using GIT.

I tried using the "http.sslcapath" configuration but this did not work. Also if i did not include the whole chain in the certificates file then this would also fail. If anyone has pointers on these please let me know as the above has to be repeated for a new install.

If this is the system GIT then you can use the options in TOOLS -> options GIt tab to use the system GIT and this then solves the issue in sourcetree as well.

"if i did not include the whole chain in the certificates file then this would also fail" - I just ran into this problem

As far as including the whole chain, I have two certs above the github cert. Do I include them in order as root->next cert->github cert in the sslcainfo.crt file?

I was able to access git repo packages by just adding the root cert.

For future readers. No idea if it matters, but I put the "root" (topmost) cert at the END of the (http.sslcainfo) file. And then as I went away from the root cert in the chain, I put that cert above the previous entry of the (http.sslcainfo) file.

I have had this issue before, and solve it using the following config.

[http "https://your.domain"] sslCAInfo=/path/to/your/domain/priviate-certificate

Since git 2.3.1, you can put https://your.domain after http to indicate the following certificate is only for it.

This is the simpliest & most precise solution I found, if you also configured git config --global http.sslCAInfo <your-server-self-signed-cert.pem> before (Hence causing the "unable to get local issuer certificate" error)

Jan 2021 - Got around this in VS2019 by setting Menu > Git > Settings > Git Global Settings > Cryptographic Network Provider > [Secure Channel] instead of [OpenSSL]

Git SSL certificate problem unable to get local issuer certificate (fix)

PS: Didn't need to set --global or --local http.sslVerify false. I was cloning an Azure DevOps repo which wasn't using any self signed certs.. This seems like an issue with either VS2019 or Git for Windows.. They need to fix it !!

The command line equivalent (for non VS2019 etc) is : git config --global http.sslBackend schannel

rc.adhikari

In my case, as I have installed the ConEmu Terminal for Window 7, it creates the ca-bundle during installation at C:\Program Files\Git\mingw64\ssl\certs.

Thus, I have to run the following commands on terminal to make it work:

$ git config --global http.sslbackend schannel
$ git config --global http.sslcainfo /mingw64/ssl/certs/ca-bundle.crt

Hence, my C:\Program Files\Git\etc\gitconfig contains the following:

[http]
    sslBackend = schannel
    sslCAinfo = /mingw64/ssl/certs/ca-bundle.crt

Also, I chose same option as mentioned here when installing the Git.

Hope that helps!

git config --global http.sslVerify false

this worked for me and missing is you need to turn verification as mentioned in the below answers

Hello, man in the middle... DON'T USE THIS! Please see here: stackoverflow.com/a/34049063/161979 .

One thing that messed me up was the format of the path (on my Windows PC). I originally had this:

git config --global http.sslCAInfo C:\certs\cacert.pem

But that failed with the "unable to get local issuer certificate" error.

What finally worked was this:

git config --global http.sslCAInfo "C:\\certs\\cacert.pem"

Celso Xavier Luz

solved my problem git config --global http.sslBackend schannel

Manjeet

Download certificate from this link: https://github.com/bagder/ca-bundle Add it to C:\Program Files\Git\bin and C:\Program Files\Git\mingw64\bin

Then try something like: git clone https://github.com/heroku/node-js-getting-started.git

Anton Tropashko

git config --global http.sslbackend secure-transport

(had to do that after update to Big Sюr)

after updating to Mac Big Sur, we too got SSL certificate problem: unable to get local issuer certificate. This fixed it!

Sérgio

To fix the especific error SSL certificate problem: unable to get local issuer certificate in git

I had the same issue with Let's Encrypt certificates .

An web site with https we just to need :

SSLEngine On
SSLCertificateFile /etc/letsencrypt/live/example.com/cert.pem
SSLCertificateKeyFile /etc/letsencrypt/live/example.com/privkey.pem
Include /etc/letsencrypt/options-ssl-apache.conf

but git pull says :

fatal: unable to access 'https://example.com/git/demo.git/': SSL certificate problem: unable to get local issuer certificate

To fix it, we need also add:

SSLCertificateChainFile /etc/letsencrypt/live/example.com/chain.pem

okan

In my case, I had to use different certificates for different git repositories.

Follow steps below (If you have a certificate of your repository, you can read from step 5)

Go to remote repository's site. Ex: github.com, bitbucket.org, tfs.example... Click Lock icon on the upper left side and click Certificate. Go to Certification Path tab and double click to .. Root Certificate Go to Details tab and click Copy to file. Export/Copy certificate to wherever you want. Ex: C:\certs\example.cer Open git bash at your local repository folder and type: $ git config http.sslCAInfo "C:\certs\example.cer"

Now you can use different certificates for each repository.

Remember, calling with the --global parameter will also change the certificates of git repositories in other folders, so you should not use the --global parameter when executing this command.

Brian Ocampo

I've had the same problem from Azure DevOps (Visual Studio). Finally I've decided to clone my repo using SSH protocol because of i've prefered it instead of disabling SSL verification.

You only need to generate a SSH Key, you can do it so... SSH documentation

ssh-keygen

And then, import your public key on yout git host (like Azure Devops, Github, Bitbucket, Gitlab, etc.)

Juan Emmanuel Afable

I had this error occur when using visual studio. This occurs when you have the Cryptographic Network provider settings set to OpenSSL in the Visual Studio Options window. When I changed the setting to Secure Channel it solved it for me. This setting must have been set for me when I upgraded my VS.

Nirbhay Jha

When using Windows, the problem resides that git by default uses the "Linux" crypto backend. Starting with Git for Windows 2.14, you can configure Git to use SChannel, the built-in Windows networking layer as the crypto backend. To do that, just run the following command in the GIT client:

git config --global http.sslbackend schannel

This means that it will use the Windows certificate storage mechanism and you don't need to explicitly configure the curl CA storage (http.sslCAInfo) mechanism.

Muhammad Bilal

This works for me. I opened cmd line and ran following command. and pulled again.

git config --global http.sslVerify false

Error

push failed fatal: unable to access SSL certificate problem: unable to get local issuer certificate

Reason

After committing files on a local machine, the "push fail" error can occur when the local Git connection parameters are outdated (e.g. HTTP change to HTTPS).

Solution

Open the .git folder in the root of the local directory Open the config file in a code editor or text editor (VS Code, Notepad, Textpad) Replace HTTP links inside the file with the latest HTTPS or SSH link available from the web page of the appropriate Git repo (clone button) Examples: url = http://git.[host]/[group/project/repo_name] (actual path) replace it with either url = ssh://git@git.[host]:/[group/project/repo_name] (new path SSH) url = https://git.[host]/[group/project/repo_name] (new path HTTPS)

arunkumar A

I have resolved the issue by adding below entry in ${HOME}/.gitconfig file

[remote "origin"]

proxy=

In most case it will happen when proxy enabled in your machine so above mentioned entry will fix this problem.

This might help some who come across this error. If you are working across a VPN and it becomes disconnected, you can also get this error. The simple fix is to reconnect your VPN.
