Abstract
Methods and systems for sending a digitally signed electronic mail (email) comprising a message are described. A first canonicalization of a first version of the message is generated. A second canonicalization of a second version of the message is also generated. A single digital signature that includes both the first and second canonicalizations is generated. The digital signature is then sent with the message.
