openpgp2ssh — translate OpenPGP keys to SSH keys
openpgp2ssh < mykey.gpg takes an
OpenPGP-formatted primary key and associated subkeys on standard input, and
spits out the requested equivalent SSH-style (or PEM-encoded) key on
If the data on standard input contains no subkeys, you can invoke
openpgp2ssh < mykey.gpg without arguments. If the
data on standard input contains multiple keys (e.g. a primary key and
associated subkeys), you must specify a specific OpenPGP key identifier as
the first argument to indicate which key to export. The key ID is normally
the 40 hex digit OpenPGP fingerprint of the key or subkey desired, but
openpgp2ssh < mykey.gpg will accept as few as the
last 8 digits of the fingerprint as a key ID.
If the input contains an OpenPGP RSA public key, it will be converted to the OpenSSH-style single-line keystring, prefixed with the key type (`ssh-rsa'). This format is suitable (with minor alterations) for insertion into known_hosts files and authorized_keys files. If invoked as `openpgp2pem', a PEM-encoded public key will be emitted instead.
If invoked as `openpgp2spki', a PEM-encoded subjectPublicKeyInfo (as defined in the X.509 standard) will be emitted instead.
If the input contains an OpenPGP RSA secret key, it will be converted to the equivalent PEM-encoded private key.
openpgp2ssh < mykey.gpg is part of the
monkeysphere(7) framework for providing a PKI for SSH.
The keys produced by this process are stripped of all identifying information, including certifications, self-signatures, etc. This is intentional, since ssh attaches no inherent significance to these features.
openpgp2ssh < mykey.gpg will produce
output for any requested RSA key. This means, among other things, that it
will happily export revoked keys, unverifiable keys, expired keys, etc. Make
sure you do your own key validation before using this tool!

openpgp2ssh < mykey.gpg and this man
page were written by Daniel Kahn Gillmor <firstname.lastname@example.org>.
openpgp2ssh < mykey.gpg only works with
RSA keys. DSA keys are the only other key type available in both OpenPGP and
SSH, but they are currently unsupported by this utility.
openpgp2ssh < mykey.gpg only accepts
raw OpenPGP packets on standard input. It does not accept ASCII-armored
openpgp2ssh < mykey.gpg Currently only
exports into formats used by the OpenSSH. It should support other key output
formats, such as those used by lsh(1) and
Secret key output is currently not passphrase-protected.
openpgp2ssh < mykey.gpg currently
cannot handle passphrase-protected secret keys on input.
