  Digital Signature Guidelines - Tutorial
Digital signatures use what is known as "public key cryptography," which employs an algorithm using two different but mathematically related "keys;" one for creating a digital signature or transforming data into a seemingly unintelligible form, and another key for verifying a digital signature or returning the message to its original form.
The complementary keys of an asymmetric cryptosystem for digital signatures are arbitrarily termed the private key, which is known only to the signer <20> and used to create the digital signature, and the public key, which is ordinarily more widely known and is used by a relying party to verify the digital signature.
Digital signature verification is the process of checking the digital signature by reference to the original message and a given public key, thereby determining whether the digital signa ture was created for that same message using the private key that corresponds to the referenced public key.

 Digital Signature - What is it?   (Site not responding. Last check: 2007-10-20)
Like the signature you use on written documents today, digital signatures are now being used to identify authors/co-signers of e-mail or electronic data.
The Digital Signature is unique to both the message and the private key used to create it, so it cannot be forged.
If the two hash results are identical, two things have been verified : that the digital signature was created using the signer's private key (assurance that the public key corresponds to the signer's private key) - no one is pretending to be or masquerading as the signer.

 The Java Community Process(SM) Program - JSRs: Java Specification Requests - detail JSR# 105   (Site not responding. Last check: 2007-10-20)
More specifically, the XML Digital Signature specification defines an XML signature element type and an XML signature application; conformance requirements for each are specified by way of schema definitions and prose respectively.
The XML Signature is a method of associating a key with referenced data; it does not normatively specify how keys are associated with persons or institutions, nor the meaning of the data being referenced and signed.
Consequently, while the XML Digital Signature specification is an important component of secure XML applications, it itself is not sufficient to address all application security/trust concerns, particularly with respect to using signed XML (or other data formats) as a basis of human-to-human communication and agreement.

 What is a Digital Signature?
A digital signature is a "stamp" Bob places on the data which is unique to Bob, and is very difficult to forge.
