### keyProxy

    protected org.mozilla.jss.pkcs11.KeyProxy keyProxy

Constructor Detail

### PK11PubKey

    protected PK11PubKey(byte[] pointer)

Method Detail

### verifyKeyIsOnToken

    public void verifyKeyIsOnToken(PK11Token token)
                            throws NoSuchItemOnTokenException

  Make sure this key lives on the given token.

  Throws:
    `NoSuchItemOnTokenException`

### getKeyType

    public KeyType getKeyType()

### getAlgorithm

    public java.lang.String getAlgorithm()

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

### fromRaw

    public static PK11PubKey fromRaw(PrivateKey.Type type,
                                     byte[] rawKey)
                              throws InvalidKeyFormatException

  Deprecated. This method works for RSA keys but not DSA or EC keys. Use fromSPKI() instead.

  Creates a PK11PubKey from its raw form. The raw form is a DER encoding of the public key. For example, this is what is stored in a SubjectPublicKeyInfo.

  Parameters:
    `type` - The type of private key to be decoded.
    `rawKey` - The bytes of the raw key.
  Throws:
    `InvalidKeyFormatException` - If the raw key could not be decoded.
  See Also:
    `fromSPKI(byte[])`

### fromSPKI

    public static PK11PubKey fromSPKI(byte[] spki)
                               throws InvalidKeyFormatException

  Creates a PK11PubKey from a SubjectPublicKeyInfo.

  Parameters:
    `spki` - The BER-encoded SubjectPublicKeyInfo.
  Throws:
    `InvalidKeyFormatException` - If the SPKI could not be decoded.

### getEncoded

    public byte[] getEncoded()

  Returns a DER-encoded SubjectPublicKeyInfo representing this key.

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

### getFormat

    public java.lang.String getFormat()

  The name of the primary encoding format of this key. The primary encoding format is X.509 SubjectPublicKeyInfo, and the name is "X.509".

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