Constructor Detail

### PK11SymKey

    protected PK11SymKey(byte[] pointer)

Method Detail

### getType

    public SymmetricKey.Type getType()

  Specified by:
    `getType` in interface `SymmetricKey`

### getOwningToken

    public CryptoToken getOwningToken()

  Specified by:
    `getOwningToken` in interface `SymmetricKey`

### getStrength

    public int getStrength()

  Returns key strength, measured as the number of bits of secret material. NOTE: Due to a bug in the security library (333440), this may return a wrong answer for PBE keys that have embedded parity (like DES). A DES key is 56 bits of information plus 8 bits of parity, so it takes up 64 bits. For a normal DES key, this method will correctly return 56, but for a PBE-generated DES key, the security library bug causes it to return 64.

  Specified by:
    `getStrength` in interface `SymmetricKey`

### getLength

    public int getLength()

  Returns the length of the key in bytes, as returned by PK11_GetKeyLength().

  Specified by:
    `getLength` in interface `SymmetricKey`

### getKeyData

    public byte[] getKeyData()
                      throws SymmetricKey.NotExtractableException

  Specified by:
    `getKeyData` in interface `SymmetricKey`
  Throws:
    `SymmetricKey.NotExtractableException`

### getKeyType

    public KeyType getKeyType()

### getAlgorithm

    public java.lang.String getAlgorithm()

  Specified by:
    `getAlgorithm` in interface `SymmetricKey`

### getEncoded

    public byte[] getEncoded()

  Specified by:
    `getEncoded` in interface `SymmetricKey`

### getFormat

    public java.lang.String getFormat()

  Specified by:
    `getFormat` in interface `SymmetricKey`
