Constructor Detail

OPKey

public OPKey(OPKey key)

Create a key object.

Parameters:

key - OPKey object.

OPKey

public OPKey(int keySet,
             int keyId,
             int keyType,
             byte[] material)

Create a key object.

Parameters:

keySet - the key set number. This number must in the range [0..255].

keyId - the key identifier. This number must be in the range [1..255].

keyType - the type of the key. Legal values must be in the range [0..255].

Method Detail

getKeyType

public int getKeyType()

getKeyType

public int getKeyType(int enc)

getMaterial

public byte[] getMaterial()

The key material.

Returns:

the key material. The returned array is shared with this instance.

getByteLength

public int getByteLength()

The key length in bytes.

Returns:

the key length in bytes (e.g. 128 for a 1024 bit RSA key)

getKeySet

public int getKeySet()

The key set version.

Returns:

the key set version. This value is in the range [1..255]

getKeyId

public int getKeyId()

The key identifier.

Returns:

the key identifier (or index). This value should be in the range [1..255].

isDESKey

public boolean isDESKey()

Reports whether this key is a DES key or not.

Returns:

true if this key is a DES key, false otherwise
