March 15, 2022 Changes made permanent. We’ll permanently stop accepting DSA keys. RSA keys uploaded after the cut-off point above will work only with SHA-2 signatures (but again, RSA keys uploaded before this date will continue to work with SHA-1). The deprecated MACs, ciphers, and unencrypted Git protocol will be permanently disabled.
Please update with a new key.
