Package java.security.spec
package 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.
