SSL certificate issue while creating git clone with TortoiseGit

Question

I want to clone the git repository with the help of TortoiseGit, but I am getting error :

error: SSL certificate problem, verify that the CA cert is OK. Details: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed while accessing https://git.assembla.com/pplconnect-PL.webserver.git/info/refs?service=git-upload-pack fatal: HTTP request failed

git did not exit cleanly (exit code 128).

Any help or guidance will be well appreciated.

Answer 1

You can choose to ignore the server certificate (at your own risk!).

Configure your TortoiseGit in the following way. First of all open the TortoiseGit settings.

Then:

1. Select the Git configuration
2. Open the global git configuration pressing "Edit systemwide gitconfig"
3. In the [http] section write:

[http]
sslVerify = false

Answer 2

Configure git to use the right root certificate. Get the root CA certificate of the server and add it to the git config. Run this in command prompt (don't forget to cd into your git repo)

git config http.sslCAinfo ~/certs/cacert.pem

You can choose to ignore the server certificate (at your own risk!).

git config http.sslVerify false

Security Warning: This is susceptible to Man in the Middle attacks. Be sure that this security concern is not an issue for you before you disable SSL certification verification.

Answer 3

All the top answers are really dangerous! Do not disable SSL verification globally!

Instead, use the excellent answer in another thread and very selectively allow a self-signed certificate for a specific site.

Edit the global .gitconfig file to include

[http "https://example.com"]
    sslCAInfo = C:\\Users\\<username>\\Documents\\ssl\\example.com.crt

The CRT file itself can be obtained in multiple ways. You can just save it using Firefox, store it somewhere safe and point your config to it.

Answer 4

The correct solution is simple: Tell Git to use the Windows certificate store. This is supported by git version >=2.14 (not sure what Tortoise version that relates to)

To configure via the command line:

1. Find the folder where git (for Tortoise git is installed) TortoiseGit -> Settings -> General Git.exe path = (e.g.) C:\Program Files\git\bin
2. In Explorer browse to this folder then shift right click "Command Prompt here"
3. Enter the following git configuration command

   git config --global http.sslBackend schannel
   

Or, from the TortoiseGit interface:

1. On the Git panel click the "Edit global .gitconfig" button.
2. If there isn't a [http] section in the file, add that line.
3. Update or add the line sslBackend = schannel to the [http] section, so it should look like:

   [http]
     sslBackend = schannel
   

Install your self signed certificate chains in the Windows Certificate Store as normal.

Answer 5

Even though disabling ssl verifyication is considered dangerous for many reasons, sometimes this is feasible. Others have pointed out to use at least a "local" disabling, but not how to do this. For the record, here is how you can define in the global .gitconfig file (in Windows located under c:\Users\username) for a single repository to use openssl and disable the check. Just add the following (adjusted) lines:

[http "https://your.repo.com"]
 sslBackend = openssl
 sslVerify = false

For me this worked perfect. As noted and linked in the answer from FRob, here is a more nuanced option that uses the pem certificate that you can often download yourself, e.g. when "clicking" on the lock symbol in your browser before the url and searching for "additional information" (firefox, others should be similar).

Answer 6

Please check that your Git for Windows installation is correct.

As you can see in the screenshot git.exe cannot find the template directory - so I suppose git.exe also cannot find the shipped CA certificates.

If that doesn't help, see a description here for including a certificate into the Git trust store.
