This value is the resulting hash derived from encrypting the contents of the message (be it the assertion or the entire response, as per your configuration). This value can then be cross checked and validated on the receiving side using the same DigestMethod (for example, SHA1) to ensure the integrity of the message.
What is DigestValue XML?
The <DigestValue> element contains a hash value based on a single message property preceded by a keyword indicating the message property used to calculate it with the hashing algorithm specified in the <DigestMethod> element.
What is XML digital signature?
An XML digital signature (XML DSIG) is an electronic, encrypted, stamp of authentication on digital information such as messages. The digital signature confirms that the information originated from the signer and was not altered in transmission. … Digital signatures are part of message-level security.
What is the purpose of XML Signature?

What is XML Security Framework?
SAML is an XML-based framework used to exchange security-related information between the client and the servers. The security information is expressed in terms of assertions, which defines how SAML assertion can transport using SOAP over HTTP.

What is Canonicalizationmethod?
In computer science, canonicalization (sometimes standardization or normalization) is a process for converting data that has more than one possible representation into a “standard”, “normal”, or canonical form.
What is canonicalization in Java?
Canonicalization is then the process of translating every string character to its single allowed encoding. An alternative is for software to determine whether a string is canonicalized, and then reject it if it is not.

What are the various elements in XML encryption?
Both XML Signature and XML Encryption use the KeyInfo element, which appears as the child of a SignedInfo , EncryptedData , or EncryptedKey element and provides information to a recipient about what keying material to use in validating a signature or decrypting encrypted data.
How is a digital signature created?
A digital signature is created using hash algorithms or a scheme of algorithms like DSA and RSA that use public key and private key encryptions. The sender uses the private key to sign the message digest (not the data), and when they do, it forms a digital thumbprint to send the data.
