public final class EntrustDSAImpl
extends EntrustDSA

Extends EntrustDSA and provides a Java software implementation of the Digital Signature Standard.

This class does not support TokenPrivateKey; the class EntrustDSAPKCS11 provides the DSS implementation for PKCS #11 token devices.

The Digital Signature Standard (DSA with SHA-1) signature algorithm is specified in FIPS PUB 186. The javadoc for EntrustDSA has a brief description.

Note

Applications should use Signature.getInstance("DSA", "Entrust"); for creating a DSA Signature object. They should not instantiate this class directly.

The following key types are currently supported:

• Standard DSA public/private keys (software keys); instances of java.security.interfaces.DSAPublicKey or java.security.interfaces.DSAPrivateKey.
• Entrust confined DSA private keys (secure software keys); instances of DsaConfinedPrivateKey.
• DSA private keys that reside on smart cards and are accessible via PKCS #11 (token keys); instances of TokenDSAPrivateKey .

Constructor Detail

EntrustDSAImpl

public EntrustDSAImpl()

Deprecated.

Default constructor.

Creates a new DSA Signature object by instantiating a raw DSA signer object and a SHA object.

Applications should use Signature.getInstance("DSA", "Entrust"); for creating a DSA Signature object. They should not instantiate this class directly.
