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 legacy OpenSSH format.
The following OpenSSH-format 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
