Email's ease and utility, which allows internal users, partners and
customers to communicate effectively, also puts confidential information in
reach of those who want to profit from it. To a moderately skilled person,
inside the organization or out, unsecured email is easy to read, impersonate
and alter, and is not much different from a postcard written in pencil.
Digital signatures on email documents represent a one-way hash
(encryption) of the message content that uses the sender's public and
private key pair. This process creates a "signature" that only the sender's
public key can decrypt. The recipient, using the sender's public key, can
then validate the sender as well as the integrity of message contents. The
sender's digital signature will be un-trusted by the recipient's email
program if either the message content or sender's digital certificate are
invalid.
The Secure Email Pro signing procedure automates the digital signature
process, and attaches the "signature" to the out-going document to be
emailed. CSE Pro also checks and validates incoming signed documents using
the reverse process.
Because the computer tenaciously pairs the digital signature to one saved
version of the document, it is nearly impossible to repudiate a digitally
signed document.
Comodo Secure Email Pro is an install-and-forget software application
that can automatically digitally sign all outgoing messages without the need
to pre-exchange passwords or public certificates. For further protection,
email documents can also be encrypted, making them unintelligible to anyone
but the intended recipient.
