sshkeys

sshkeys is a small library for reading SSH public keys, extracting some information from them and possibly outputting them again. It’s mainly useful when dealing with scripts that manipulate ~/.ssh/authorized_keys or handle user’s public keys in other ways.

sshkeys supports Python 2.6, 2.7, 3.3, 3.4.

Example

Here’s a small example session:

>>> from sshkeys import Key
>>> k = Key.from_pubkey_file('sample_rsa.key.pub')
>>> print k.readable_fingerprint
b9:e2:58:1a:74:fc:62:13:52:ad:f7:28:0b:09:91:54
>>> print k.comment
sample_rsa_key@host
>>> k.comment = 'command="nothing",no-x11-forwarding'
>>> print k.to_pubkey_line()
