A key may be specified in an algorithm-specificway, or in an algorithm-independent encoding format (such as ASN.1).This package contains key specifications for DSA public and private keys,RSA public and private keys, PKCS #8 private keys in DER-encoded format,and X.509 public and private keys in DER-encoded format.<p>An algorithm parameter specification is a transparent representationof the sets of parameters used with an algorithm.
