## Package javax.xml.crypto.dsig.keyinfo Description

Classes for parsing and processing `KeyInfo` elements and structures. `KeyInfo` is an optional element that enables the recipient(s) to obtain the key needed to validate an `XMLSignature`. `KeyInfo` may contain keys, names, certificates and other public key management information, such as in-band key distribution or key agreement data. This package contains classes representing types defined in the W3C specification for XML Signatures, such as `KeyName`, `KeyValue`, `RetrievalMethod`, `X509Data`, `X509IssuerSerial`, and `PGPData`. `KeyInfoFactory` is an abstract factory that creates `KeyInfo` objects from scratch.
