Class EncodedKeySpec

    • Constructor Detail

      • EncodedKeySpec

        public EncodedKeySpec​(byte[] encodedKey)
        Creates a new EncodedKeySpec with the given encoded key.
        Parameters:
        encodedKey - the encoded key. The contents of the array are copied to protect against subsequent modification.
        Throws:
        NullPointerException - if encodedKey is null.
      • EncodedKeySpec

        protected EncodedKeySpec​(byte[] encodedKey,
                                 String algorithm)
        Creates a new EncodedKeySpec with the given encoded key. This constructor is useful when subsequent callers of the EncodedKeySpec object might not know the algorithm of the key.
        Parameters:
        encodedKey - the encoded key. The contents of the array are copied to protect against subsequent modification.
        algorithm - the algorithm name of the encoded key See the KeyFactory section in the Java Security Standard Algorithm Names Specification for information about standard algorithm names.
        Throws:
        NullPointerException - if encodedKey or algorithm is null.
        IllegalArgumentException - if algorithm is the empty string ""
        Since:
        9
    • Method Detail

      • getAlgorithm

        public String getAlgorithm()
        Returns the name of the algorithm of the encoded key.
        Returns:
        the name of the algorithm, or null if not specified
        Since:
        9
      • getEncoded

        public byte[] getEncoded()
        Returns the encoded key.
        Returns:
        the encoded key. Returns a new array each time this method is called.
      • getFormat

        public abstract String getFormat()
        Returns the name of the encoding format associated with this key specification.

        If the opaque representation of a key (see Key) can be transformed (see KeyFactory) into this key specification (or a subclass of it), getFormat called on the opaque key returns the same value as the getFormat method of this key specification.

        Returns:
        a string representation of the encoding format.
