DecodeFromEnv reads the processes environment data and decodes the host and user keys from it, returning ready to use representations of those keys.

GenerateKeys generates a new SSHKeyMaterial with random keys.

MarshalPrivateKey converts the key to a string, such that UnmarshalPrivateKey can return the same key.

MarshalPublicKey converts a PubilcKey into a string that can be decoded by UnmarshalPublicKey.

UnmarshalPrivateKey parses the string into a rsa.PrivateKey.

UnmarshalPublicKey parses a string into a PubilcKey.

hostKey contains an SSH RSA private key, marshaled as PKCS1 and armored with base64.

Contains the port that the ssh server should listen on.

SSHKeyMaterial holds the key material required to setup an SSH connection between a server and client.
