brew installed Python 2.7.13

paramiko (2.3.0)
bcrypt (3.1.3)
cryptography (2.0.3)
pyasn1 (0.3.6)
PyNaCl (1.1.2)

Downgrade to 2.2.2 fixed the problem.

It seems that Ed25519Key doesn't initialize public_blob property like ECDSAKey, or other PKey descendants

It was deleted here 59f9a64#diff-87395d54ac5abc2ace279f1e60fe5fd9L66

Hrm, that means both A) there's a hole in our test suite and B) I probably needed to move that line to the top of __init__ instead of simply deleting it. Will take a peek, thanks!

Hrm we're testing basic connectivity with Ed25519 user keys. Ah! But since we need certs around to test that functionality, and certs get automatically loaded (as per OpenSSH compatible behavior), our test keys always load the certs & thus have public_blob set. So I'll probably want to move the certs and copies of their keys into a separate location to avoid this.

[bitprophet]

Confirmed that once I do that, this error pops up, so now I can test the fix.
