derivepassphrase.git

1) ### Added

2) 

3)   - Checking whether an SSH key is suitable now also depends on the SSH

4)     agent in use.  API functions now optionally take an additional

5)     [`SSHAgentClient`][derivepassphrase.ssh_agent.SSHAgentClient] object to

6)     test agent-specific key suitability.  If not given, then the old
7)     behavior is retained: SSH keys are suitable if they are suitable under
8)     any (conforming) SSH agent.
9) 
10) ### Fixed
11) 

12)   - If the SSH agent supports deterministic DSA/ECDSA signatures (e.g.

13)     [RFC 6979][]), then mark DSA and ECDSA SSH keys as suitable.
