SessionOptions.SshHostKeyFingerprint does not accept 1024 bit fingerprints.

Hello All,

I’m trying to connect to a server via SFTP w/ fingerprint and it throws with the reason stated as “SSH Host fingerprint does not match pattern, as you can see on the screenshot attached.

According to what I see in the mentioned pattern, it expects only 256/384/512 bit fingerprints; moreover, there’s a typo there (521 instead of 512).

Thank you for your attention.

Sorry, for some reason I was mistaken as “Guest” user. This is my forum acc.

You misinterpret the regular expression. The 1024 is not the problem.

Show us your full fingerprint. It's fingerprint of a public key. It's not a secret.

And the 521 is not a typo.

The full key is:


That is exactly what PuTTY returns me when I try to connect manually.
Thank you for the prompt reply!

Case closed, this was due to a hard-to-recognize typo in the key given to me. Thank you and sorry for bothering.
