OFF-TOPIC: SSH authn over TLS?

[Felipe Gasper <felipe@xxxxxxxxxxxxxxxx>]

Hello,

	I want to rig up a simple authentication based on SSH keys but over a preexisting TLS connection.

	Since TLS already handles the encryption, would the authentication be as simple as verifying a decode of a string that the public key encodes?

	Is there any prior art for this?

	(I realize this isn’t really on-topic for this list, but I’m not sure where else to ask … ?)

	Thank you!
