hi:
I write a SSH server with Twisted(15.5.0) Conch. But it don't
support hmac-sha2-512 MAC algorithms
. However I see this problem has been fixed in
https://twistedmatrix.com/trac/ticket/8108 . I asked the question in http://stackoverflow.com/questions/41254398/twisted-hmac-sha2-512-corrupted-... .
Hi, #8108 did not fix hmac-sha2-512, but was an attempt to add support for it. Since there were no automated tests, hmac-sha2-512 was never functional. There is a defect ticket which is not yet closed https://twistedmatrix.com/trac/ticket/8258 I hope that the ticket description can be used to reproduce this error. This might not be a hmac-sha2-512 specific issue, but a generic issue related to padding... is just that sha2-512 triggered it. -- Adi Roiban
