Next Generation Application Integration: From Simple Information to Web Services

XML Signature

Before we understand what XML Signature is, we must first understand what digital signatures are. A digital signature leverages encryption technology to support nonrepudiation, or the ability to validate that a party has “signed off” on a particular document. This is a binding legal agreement, such as ordering custom-built products. Digital signatures, in general, rely on public key cryptography, applying a signing encryption algorithm with a private key. The receiver can validate the signature by using a verification encryption algorithm, and thus the generated value should match up. If the information is different, then they won't match and the signature will be invalid.

This is important in the world of application integration ...
