[auth.c key.c key.h ssh-keygen.1 ssh-keygen.c sshd_config.5]
     [krl.c krl.h PROTOCOL.krl]
     add support for Key Revocation Lists (KRLs). These are a compact way to
     represent lists of revoked keys and certificates, taking as little as
     a single bit of incremental cost to revoke a certificate by serial number.
     KRLs are loaded via the existing RevokedKeys sshd_config option.
