GPGMAILTUNL(1) User Contributed Perl Documentation GPGMAILTUNL(1)NAMEgpgmailtunl - Encrypts an email message into the body of another email.
SYNOPSISgpgmailtunl [options] --encrypt | --decrypt
DESCRIPTIONgpgmailtunl is a filter program that either encrypts an email message
using the Gnu Privacy Guard and sends it to another recipient or
decrypt an email message and forwards unencrypted to another
destination.
It can be used to exchange emails across an open network betweeen two
trusted systems.
TYPICAL USAGE
This program is intended to run from program like procmail or sendmail
to create an email tunnel between two systems. Of course this is not
as secure as using gpg as an end user program, it may be convenient in
certain case.
ENCRYPTION
To encapsulates an email within another you pipe the message to
gpgmailtunl.
OPTIONS
GetOptions( \%opt, "encrypt", "decrypt", "sign", "secret-file=s",
"from=s", "to=s", "subject=s", "homedir=s", "local-user=s",
"recipient=s", )
or usage;
to This is the address to which the encrypted message will be sent.
This is the only required fields.
recipient
This sets the keyid that will be used to encrypt the outgoing
message. If unset, gpgmailtunl will try to find a key matching the
to option.
subject
Sets the subject of the outgoing message. This defaults to
"Encrypted mail".
from
Sets the From header line of the outgoing message which will
contains the encrypted one. sendmail will provides a default one if
this is not set.
sign
If this option is used, the outgoing message will be signed. In
this case you should probably use to local-user and secret-file
options.
secret-file
File from which the secret to unlock the private used to sign the
message can be read.
local-user
The keyid of the user that should sign the outgoing message. The
default user will be used if not specified.
homedir
Sets an alternate gpg home directory. (This is where the keyrings
are stored.)
DECRYPTION
To extract an email to be forwarded to the final user you pipe the
encrypted email to gpgmailtunl using the decrypt switch.
Once decrypted, the encapsulated email message will be sent to the
original destinator of the message.
OPTIONS
homedir
Sets an alternate gpg home directory. (This is where the keyrings
are stored.)
secret-file
File from which the secret to unlock the private used to decrypt
the message can be read.
