## Package javax.xml.crypto.dsig Description

Classes for generating and validating XML digital signatures. This package includes classes that represent the core elements defined in the W3C XML digital signature specification: `XMLSignature`, `SignedInfo`, `CanonicalizationMethod`, `SignatureMethod`, `Reference`, `DigestMethod`, `XMLObject`, `Manifest`, `SignatureProperties`, and `SignatureProperty`. `KeyInfo` types are defined in the `javax.xml.crypto.dsig.keyinfo` subpackage. `XMLSignatureFactory` is an abstract factory that creates `XMLSignature` objects from scratch or from a pre-existing XML representation, such as a DOM node. `TransformService` is a service provider interface for creating and plugging in implementations of transform and canonicalization algorithms.

Of primary significance in this package is the `XMLSignature` class, which allows you to sign and validate an XML digital signature.

## Package Specification

- XML-Signature Syntax and Processing: W3C Recommendation
- RFC 3275: XML-Signature Syntax and Processing
