My git client claimserror: Peer's Certificate issuer is not recognized.That means it can not find the corresponding ssl server key in the global system keyring. I want to check this by looking at the list of all system wide available ssl keys on a gentoo linux system. How can I get this list?
List all available ssl ca certificates
linux;openssl
It's not SSL keys you want, it's certificate authorities, and more precisely their certificates.You could try:awk -v cmd='openssl x509 -noout -subject' '    /BEGIN/{close(cmd)};{print | cmd}' < /etc/ssl/certs/ca-certificates.crtTo get the subject of every CA certificate in /etc/ssl/certs/ca-certificates.crtBeware that sometimes, you get that error when SSL servers forget to provided the intermediate certificates.Use openssl s_client -showcerts -connect the-git-server:443 to get the list of certificates  being sent.
