The generated certificates +include the secret key material, so they should be handled carefully. +.Pp +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. +.Pp +Other choices about how to generate the new OpenPGP certificate are +governed by environment variables. +.Sh ENVIRONMENT +The following environment variables influence the behavior of +.Nm : +.Pp +.ti 3 +\fBPEM2OPENPGP_TIMESTAMP\fP 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. By default, +.Nm +uses the current time. +.Pp +.ti 3 +\fBPEM2OPENPGP_USAGE_FLAGS\fP 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, +.Nm +only sets the certify flag. +.Pp +.ti 3 +\fBPEM2OPENPGP_EXPIRATION\fP 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. +.Pp +.ti 3 +\fBPEM2OPENPGP_NEWKEY\fP indicates that +.Nm +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), +.Nm +will read the key from stdin. .Sh AUTHOR .Nm and this man page were written by Daniel Kahn Gillmor <dkg@fifthhorseman.net>. .Sh BUGS +Only handles RSA keys at the moment. It would be nice to handle DSA +keys as well. +.Pp +Currently only creates certificates with a single User ID. Should be +able to create certificates with multiple User IDs. +.Pp +Currently only accepts unencrypted RSA keys. It should be able to +deal with passphrase-locked key material. +.Pp +Currently outputs OpenPGP certificates with cleartext secret key +material. It would be good to be able to lock the output with a +passphrase. +.Pp +If you find other bugs, please report them at +https://labs.riseup.net/code/projects/show/monkeysphere .Sh SEE ALSO .Xr openpgp2ssh 1, .Xr monkeysphere 1 , .Xr monkeysphere 7 , .Xr ssh 1 , -.Xr monkeysphere-server 8 +.Xr monkeysphere-host 8 , +.Xr monkeysphere-authentication 8 |
