Attempt to fix rsa ssh

[mxswd]

For whatever reason the signature I'm sending to OpenSSH doesn't validate and the connection gets rejected.

If you have any ideas let me know.

This is how I'm encoding the signature: https://github.com/maxgoedjen/secretive/pull/457/files#diff-2aed467ebf696ae8d53d908364621e918247939acdb9e57463a9a91dd407710bR158

Which looks correct according to: https://www.ietf.org/rfc/rfc8332.txt
