PGP/MIME standard

Top  Previous  Next

PGP/MIME stands for Pretty Good Privacy/Multipurpose Internet Mail Extensions


The PGP/MIME standard provides secure messaging to conform to:


† RFC 1991 PGP Message Exchange Formats
† RFC 2015 MIME Security with Pretty Good Privacy (PGP)
† RFC 2440 OpenPGP Message Format
† RFC 3156 MIME Security with OpenPGP


With PGP/MIME encrypting and signing of your e-mails is easier and more flexible than ASCII armoured.


In The Bat! PGP/MIME is set as default, it will be used for signing/encrypting when:


† a message includes attachments
† a message is in HTML or Rich Text Format
† a non-ASCII character set is used
† the text contains lines longer than 76 characters
† the text features lines beginning with "From"
† the text contains lines with trailing spaces like the standard signature delimiter


Beware: To read encrypted messages the recipient needs to have OpenPGP installed, too!

Note: Some e-mail clients (i.e. Webmailers) may have trouble with PGP/MIME-signed messages. For those recpients not being able to read a signed message you can use the %NOPGPMIME macro in a template. You can also disable automatic signing and use the %PGPMIME macro in templates for people you want to send signed messages to.
