Signed content
Whenever information is transferred/uploaded electronically, it can accidentally or
willfully be altered. To overcome this, some software use a digital signature - the
electronic form of a handwritten signature.
A digital signature is extra information added to an email message that identifies and
authenticates the information in that email. It is encrypted and acts like a unique
summary of the information that is signed with a message digest in the email message.
If the email message contains a virus, bad content or is too large, the software might
clean or remove some part of the message. The email is still valid, and can be read, but
the original digital signature is 'broken'. You cannot rely on the contents of the email
because the contents might also have been altered in other ways. Signed content
policy specifies how email messages with digital signatures are handled.
