This package provides the classes and interfaces needed to specify keys and parameter for encryption. Following standards are supported: (1) PKCS#3 Diffie-Hellman ekey agreement's standard; (2) FIPS-46-2 Data Encryption Standard (DES); (3) PKCS#5 Password Based Encryption (PBE) 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: (i) DH, (ii) DES, (iii) TripleDES, (iv) PBE, (v) RC2 and (vi) RC5.
