                    java.security.interfaces.DSAParams params)

Construct a public key from the given values. No parameter checking is done.

Method Detail

getY

public java.math.BigInteger getY()

Returns public value Y.

Specified by:

getY in interface java.security.interfaces.DSAPublicKey

---

getParams

public java.security.interfaces.DSAParams getParams()

Return DSA parameters (g,q, p).

Specified by:

getParams in interface java.security.interfaces.DSAKey

---

getAlgorithm

public java.lang.String getAlgorithm()

Description copied from interface: java.security.Key

This method returns the name of the algorithm for this key. This is a String such as "RSA".

Specified by:

getAlgorithm in interface java.security.Key

---

getFormat

public java.lang.String getFormat()

Description copied from interface: java.security.Key

This method returns the name of the encoding format for this key. This is the name of the ASN.1 data format used for this key, such as "X.509" or "PKCS#8". This method returns null if this key does not have an encoding format.

Specified by:

getFormat in interface java.security.Key

---
