NAME

     pem2openpgp -- translate PEM-encoded RSA keys to OpenPGP certificates

SYNOPSIS

     pem2openpgp $USERID < mykey.pem | gpg --import

     PEM2OPENPGP_EXPIRATION=$((86400 * $DAYS))
                 PEM2OPENPGP_USAGE_FLAGS=authenticate,certify pem2openpgp
                 $USERID <mykey.pem

DESCRIPTION

     pem2openpgp is a low-level utility for transforming raw, PEM-encoded RSA
     secret keys into OpenPGP-formatted certificates.  The generated
     certificates include the secret key material, so they should be handled
     carefully.

     It works as an element within a pipeline: feed it the raw key on stdin,
     supply the desired User ID as a command line argument.  Note that you may
     need to quote the string to ensure that it is entirely in a single
     argument.

     Other choices about how to generate the new OpenPGP certificate are
     governed by environment variables.

ENVIRONMENT

     The following environment variables influence the behavior of
     pem2openpgp:

   PEM2OPENPGP_TIMESTAMP controls the timestamp (measured in seconds since the
     UNIX epoch) indicated as the creation time (a.k.a "not valid before") of
     the generated certificate (self-signature) and the key itself.  By
     default, pem2openpgp uses the current time.

   PEM2OPENPGP_KEY_TIMESTAMP controls the timestamp (measured in seconds since
     the UNIX epoch) indicated as the creation time of just the key itself
     (not the self-signature).  By default, pem2openpgp uses the value from
     PEM2OPENPGP_TIMESTAMP.

   PEM2OPENPGP_USAGE_FLAGS should contain a comma-separated list of valid
     OpenPGP usage flags (see section 5.2.3.21 of RFC 4880 for what these
     mean).  The available choices are: certify, sign, encrypt_comms,
     encrypt_storage, encrypt (this means both encrypt_comms and
     encrypt_storage), authenticate, split, shared.  By default, pem2openpgp
     only sets the certify flag.

   PEM2OPENPGP_EXPIRATION sets an expiration (measured in seconds after the
     creation time of the key) in each self-signature packet.  By default, no
     expiration subpacket is included.

   PEM2OPENPGP_NEWKEY indicates that pem2openpgp should ignore stdin, and
     instead generate a new key internally and build the certificate based on
     this new key.  Set this variable to the number of bits for the new key
     (e.g. 2048).  By default (when this is unset), pem2openpgp will read the
     key from stdin.

BUGS

     Only handles RSA keys at the moment.  It might be nice to handle DSA keys
     as well.

     Currently only creates certificates with a single User ID.  Should be
     able to create certificates with multiple User IDs.

     Currently only accepts unencrypted RSA keys.  It should be able to deal
     with passphrase-locked key material.

     Currently outputs OpenPGP certificates with cleartext secret key
     material.  It would be good to be able to lock the output with a
     passphrase.
