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 diff --git a/src/keytrans/pem2openpgp b/src/keytrans/pem2openpgp index c765002..2631da6 100755 --- a/src/keytrans/pem2openpgp +++ b/src/keytrans/pem2openpgp @@ -347,13 +347,16 @@ sub fingerprint { return Digest::SHA1::sha1(pack('Cn', 0x99, length($rsabody)).$rsabody); } -# we're just not dealing with newline business right now. slurp in -# the whole file. -undef $/; -my $buf = <STDIN>; - -my $rsa = Crypt::OpenSSL::RSA->new_private_key($buf); +my $rsa; +if (defined $ENV{PEM2OPENPGP_NEWKEY}) { + $rsa = Crypt::OpenSSL::RSA->generate_key($ENV{PEM2OPENPGP_NEWKEY}); +} else { + # we're just not dealing with newline business right now. slurp in + # the whole file. + undef $/; + $rsa = Crypt::OpenSSL::RSA->new_private_key(<STDIN>); +} $rsa->use_sha1_hash(); diff --git a/src/monkeysphere-authentication b/src/monkeysphere-authentication index 4485bd4..6d2e72c 100755 --- a/src/monkeysphere-authentication +++ b/src/monkeysphere-authentication @@ -70,19 +70,6 @@ subcommands: EOF } -# function to run command as monkeysphere user -su_monkeysphere_user() { - # if the current user is the monkeysphere user, then just eval - # command - if [ $(id -un) = "$MONKEYSPHERE_USER" ] ; then - eval "$@" - - # otherwise su command as monkeysphere user - else - su "$MONKEYSPHERE_USER" -c "$@" - fi -} - # function to interact with the gpg core keyring gpg_core() { GNUPGHOME="$GNUPGHOME_CORE" @@ -184,7 +171,7 @@ case $COMMAND in list_certifiers "$@" ;; - 'expert'|'e') + 'expert') SUBCOMMAND="$1" shift case "$SUBCOMMAND" in diff --git a/src/monkeysphere-host b/src/monkeysphere-host index a6fa62f..be398b1 100755 --- a/src/monkeysphere-host +++ b/src/monkeysphere-host @@ -14,6 +14,9 @@ ######################################################################## set -e +# set the pipefail option so pipelines fail on first command failure +set -o pipefail + PGRM=$(basename $0) SYSSHAREDIR=${MONKEYSPHERE_SYSSHAREDIR:-"/usr/share/monkeysphere"} @@ -65,70 +68,98 @@ subcommands: EOF } -# function to run command as monkeysphere user -su_monkeysphere_user() { - # if the current user is the monkeysphere user, then just eval - # command - if [ $(id -un) = "$MONKEYSPHERE_USER" ] ; then - eval "$@" +# function to interact with the gpg keyring +gpg_host() { + GNUPGHOME="$GNUPGHOME_HOST" gpg "$@" +} + +# command to list the info about the host key, in colon format +gpg_host_list() { + gpg_host --list-keys --with-colons --fixed-list-mode \ + --with-fingerprint --with-fingerprint \ + "0x${HOST_FINGERPRINT}!" - # otherwise su command as monkeysphere user - else - su "$MONKEYSPHERE_USER" -c "$@" - fi } -# function to interact with the gpg keyring -gpg_host() { - local returnCode +# command for edit key scripts, takes scripts on stdin +gpg_host_edit() { + gpg_host --quiet --command-fd 0 --edit-key \ + "0x${HOST_FINGERPRINT}!"
