Field Detail

### keyProxy

    protected org.mozilla.jss.pkcs11.KeyProxy keyProxy

Constructor Detail

### PK11PrivKey

    protected PK11PrivKey(byte[] pointer)

Method Detail

### verifyKeyIsOnToken

    public void verifyKeyIsOnToken(PK11Token token)
                            throws NoSuchItemOnTokenException

  Make sure this key lives on the given token.

  Throws:
    `NoSuchItemOnTokenException`

### getOwningToken

    public CryptoToken getOwningToken()

  Returns a new CryptoToken where this key resides.

  Returns:
    The PK11Token that owns this key.

### getUniqueID

    public byte[] getUniqueID()
                       throws TokenException

  Description copied from interface: `PrivateKey`
  Returns the unique ID of this key. Unique IDs can be used to match certificates to keys.

  Throws:
    `TokenException`
  See Also:
    `TokenCertificate.getUniqueID()`

### getKeyType

    public KeyType getKeyType()

### getType

    public PrivateKey.Type getType()

  Description copied from interface: `PrivateKey`
  Returns the type (RSA or DSA) of this private key.

### getAlgorithm

    public java.lang.String getAlgorithm()

  Specified by:
    `getAlgorithm` in interface `java.security.Key`

### getStrength

    public int getStrength()

  Returns the size in bits of the modulus of an RSA Private key. Returns -1 for other types of keys.

### fromPrivateKeyInfo

    public static PK11PrivKey fromPrivateKeyInfo(java.security.spec.PKCS8EncodedKeySpec spec,
                                                 CryptoToken token)
                                          throws TokenException

  Imports a PrivateKeyInfo, storing it as a temporary PrivateKey on the given token. The key will be a temporary (session) key until it is imported into a KeyStore, at which point it will be made a permanent (token) object.

  Throws:
    `TokenException`

### fromPrivateKeyInfo

    public static PK11PrivKey fromPrivateKeyInfo(byte[] pki,
                                                 CryptoToken token)
                                          throws TokenException

  Imports a PrivateKeyInfo, storing it as a temporary PrivateKey on the given token. The key will be a temporary (session) key until it is imported into a KeyStore, at which point it will be made a permanent (token) object.

  Throws:
    `TokenException`

### fromPrivateKeyInfo

    public static PK11PrivKey fromPrivateKeyInfo(byte[] pki,
                                                 CryptoToken token,
                                                 byte[] publicValue)
                                          throws TokenException

  Imports a PrivateKeyInfo, storing it as a temporary PrivateKey on the given token. The key will be a temporary (session) key until it is imported into a KeyStore, at which point it will be made a permanent (token) object.

  Parameters:
    `publicValue` - An encoding of the public key, as used by the NSS pk11wrap code. Don't use this unless you know what you're doing.
  Throws:
    `TokenException`

### getDSAParams

    protected java.security.spec.DSAParameterSpec getDSAParams()
                                                        throws TokenException

  Throws:
    `TokenException`

### getEncoded
