Yes, I need that. ^__^

This feature is already in earthworm:
https://coolbug.org/earthworm/

https://repo.coolbug.org/bug/earthworm

porting for pagure coming soon

Done

generate

By the first generate your private key and self-signed SSL client certificate:

openssl genrsa -out private-key.pem 2048
openssl req -new -key private-key.pem -out client-certificate.csr
openssl x509 -req -days 3650 -in client-certificate.csr -signkey private-key.pem -out certificate.pem

Now your public cert in a certificate.pem and private key in private-key.pem
client-certificate.csr - does not required any more

git

Let's configure git - add following lines into config:

[http "https://coolbug.org"]
     sslCert = "/path/to/certificate.pem"
     sslKey = "/path/to/private-key.pem"
     sslVerify = true
     sslCertPasswordProtected = false
[http "https://repo.coolbug.org"]
     sslCert = "/path/to/certificate.pem"
     sslKey = "/path/to/private-key.pem"
     sslVerify = true
     sslCertPasswordProtected = false

earthworm

Edit your profile in Earthworm, just copy content of certificate.pem into field Add client SSL certificate, data, and press Submit

pagure

Now Pagure. Pagure stores only SSH keys, but we can convert RSA public key from SSL certificate into ssh-rsa format:

openssl x509 -in certificate.pem -pubkey -noout | ssh-keygen -f /dev/stdin -i -mPKCS8

Copy result of this command into Pagure (my settings -> ssh keys).

Tested with Pagure - it worked! Thank you! ^__^
