Class SRPParameters

java.lang.Object
  org.jboss.security.srp.SRPParameters

All Implemented Interfaces:

Serializable, Cloneable

public class SRPParameters
extends Object
implements Cloneable, Serializable

The RFC2945 algorithm session parameters that the client and server agree to use. In addition to the base RFC2945 parameters, one can choose an alternate hash algorithm for the private session key.

Field Detail

N

public final byte[] N

The algorithm safe-prime modulus

g

public final byte[] g

The algorithm primitive generator

s

public final byte[] s

The random password salt originally used to verify the password

hashAlgorithm

public final String hashAlgorithm

The algorithm to hash the session key to produce K. To be consistent with the RFC2945 description this must be SHA_Interleave as implemented by the JBossSX security provider. For compatibility with earlier JBossSX SRP releases the algorithm must be SHA_ReverseInterleave. This name is passed to java.security.MessageDigest.getInstance().

cipherAlgorithm

public final String cipherAlgorithm

The algorithm to use for any encryption of data.

cipherIV

public byte[] cipherIV

The cipher intialization vector bytes
