By default, the Tectia client/server solution uses private and public keys stored in the IETF standard Secure Shell v2 format. However, Tectia Client and Server can also use keys and related files in the OpenSSH format and OpenSSL PEM format.
The following OpenSSH/OpenSSL-PEM keys are supported:
server host key pair
trusted server host public keys, which clients use to authenticate servers
user private keys (used by clients to authenticate to a server)
authorized user public keys (used by a server to authenticate users), including public-key options
