.Sh DESCRIPTION
.Nm
takes an OpenPGP-formatted primary key and associated
will accept as few as the last 8 digits of the fingerprint as a key
ID.
.Pp
-If the input contains an OpenPGP RSA or DSA public key, it will be
-converted to the OpenSSH-style single-line keystring, prefixed with
-the key type. This format is suitable (with minor alterations) for

+(`ssh\-rsa'). This format is suitable (with minor alterations) for
insertion into known_hosts files and authorized_keys files.

.Nm
is part of the

+.Xr monkeysphere 7
framework for providing a PKI for SSH.
.Sh CAVEATS
The keys produced by this process are stripped of all identifying
features.
.Pp
.Nm
-only works with RSA or DSA keys, because those are the
-only ones which work with ssh.
-.Pp
-Assuming a valid key type, though,
-.Nm
-will produce output for
-any requested 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!

.Sh EXAMPLES
-.Nm gpg --export-secret-key $KEYID | openpgp2ssh $KEYID | ssh-add -c /dev/stdin
+.Nm gpg \-\-export\-secret\-key $KEYID | openpgp2ssh $KEYID | ssh\-add \-c /dev/stdin
.Pp
This pushes the secret key into the active

Tools such as
.Xr ssh 1
which know how to talk to the
-.Xr ssh-agent 1
+.Xr ssh\-agent 1
can now rely on the key.

.Sh BUGS
.Nm
+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.
+.Pp
+.Nm
+only accepts raw OpenPGP packets on standard input. It does not
+accept ASCII-armored input.
+.Nm
Currently only exports into formats used by the OpenSSH.
It should support other key output formats, such as those used by
-lsh(1) and putty(1).
+.Xr lsh 1
+and
+.Xr putty 1 .
.Pp
Secret key output is currently not passphrase-protected.
.Pp
.Nm
currently cannot handle passphrase-protected secret keys on input.
-.Pp
-Key identifiers consisting of an odd number of hex digits are not
-accepted. Users who use a key ID with a standard length of 8, 16, or
-40 hex digits should not be affected by this.
-.Pp
-.Nm
-only acts on keys associated with the first primary key
-passed in. If you send it more than one primary key, it will silently
-ignore later ones.
