java.security.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 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.
An algorithm parameter specification is a transparent representation
of the sets of parameters used with an algorithm. This package contains
an algorithm parameter specification for parameters used with the
DSA algorithm.
