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.
