    3535At the least, we need to have a way to convert the private key from one format to another.  While i have no problem using an OpenSSH-generated RSA private key as the private part of an X.509 key/cert pair (and vice versa), i'm having difficulty figuring out how to translate the PEM-encoded RSA keys into OpenPGP-encoded RSA keys.

    37 This conversion should be do-able by reading [RFC:4880#section-5.5.2 the OpenPGP spec for Secret Key packet formats] and [RFC:3447#appendix-A.1.2 the RSA encryption standard's Private Key Syntax].  It's also possible that GnuTLS (which is capable of dealing with both OpenPGP and X.509/PEM) might be able to do the conversion.

    40 We'll also probably need to be able to translate public keys, since the keyservers will offer [RFC:4880#section-5.5.1 OpenPGP-formatted public keys], but OpenSSH's `ssh-keygen` [http://sourceforge.net/docman/display_doc.php?docid=761&group_id=1#key_conversion can convert] from [RFC:4716 the IETF's SECSH Public Key Format], which is different.  AFAICT, `ssh-keygen` isn't capable of converting from an OpenPGP public key.  When i try it, i get:
