- monkeysphere private key translator: execute this with an GPG
- secret key on stdin (at the moment, only passphraseless RSA keys
- work).
-
- It will spit out a PEM-encoded version of the key on stdout, which
- can be fed into ssh-add like this:
-
- gpg --export-secret-keys $KEYID | monkeysphere | ssh-add -c /dev/stdin
-
- Requirements: I've only built this so far with GnuTLS v2.3.4 --
- version 2.2.0 does not contain the appropriate pieces.
-
- Notes: gpgkey2ssh doesn't seem to provide the same public
- keys. Mighty weird!

-gnutls version: 2.3.4
-OpenPGP RSA Key, with 1024 bits
-Identity added: /dev/stdin (/dev/stdin)
