Module java.base

Package javax.crypto.spec

package javax.crypto.spec
Provides classes and interfaces for key specifications and algorithm parameter specifications.

A key specification is a transparent representation of the key material that constitutes a key. A key may be specified in an algorithm-specific way, or in an algorithm-independent encoding format (such as ASN.1). This package contains key specifications for Diffie-Hellman public and private keys, as well as key specifications for DES, Triple DES, and PBE secret keys.

An algorithm parameter specification is a transparent representation of the sets of parameters used with an algorithm. This package contains algorithm parameter specifications for parameters used with the Diffie-Hellman, DES, Triple DES, PBE, RC2 and RC5 algorithms.
