Module ssh_keys 

SSH public keys on isb accounts: what isb ssh-proxy lets into an instance (docs/guides/ssh.md).

A key is stored as its algorithm and base64 blob only, re-validated on the way in: no authorized_keys options (command=, from=), no comment, nothing that could add a line or an option when it is written into an instance. Its comment becomes the key’s name. The fingerprint is OpenSSH’s (SHA256: and unpadded base64 of the blob’s SHA-256), so it matches what ssh-keygen -lf and sshd’s log print.

Structs

PublicKey

Constants

ALGORITHMS

The key types accepted: OpenSSH’s current ones. DSA is long gone.

MAX_KEYS

How many keys one account may hold.

Functions

fingerprint_of
