[Twisted-Python] hmac-sha2-512 - Corrupted MAC on input with OpenSSH

[Craig Rodrigues]

Hi,

Is this what you are saying:

Twisted Server + OpenSSH client == WORKS
Twisted Server + Xshell client == WORKS
OpenSSH Server + SecureCRT client == WORKS
Twisted Server + SecureCRT client == FAIL

??

I don't have SecureCRT client, so don't know the solution to this problem.

You might want to try searching the SecureCRT site and see if there are any
clues
there:
