Javax.Crypto.Spec Namespace

This package provides the classes and interfaces needed to specify keys and parameter for encryption.

Remarks

This package provides the classes and interfaces needed to specify keys and parameter for encryption. The following standards are supported:

  • PKCS#3 Diffie-Hellman Key Agreement standard;
  • FIPS-46-2 Data Encryption Standard (DES);
  • PKCS#5 Password-Based Cryptography standard.

Keys may be specified via algorithm or in a more abstract and general way with ASN.1.

Keys and algorithm parameters are specified for the following procedures:

  • DH
  • DES
  • TripleDES
  • PBE
  • RC2
  • RC5
