Constructor Detail- 
EncodedKeySpecpublic EncodedKeySpec(byte[] encodedKey) Creates a newEncodedKeySpecwith the given encoded key.- Parameters:
- encodedKey- the encoded key. The contents of the array are copied to protect against subsequent modification.
- Throws:
- NullPointerException- if- encodedKeyis null.
 
 - 
EncodedKeySpecprotected EncodedKeySpec(byte[] encodedKey, String algorithm)Creates a newEncodedKeySpecwith the given encoded key. This constructor is useful when subsequent callers of theEncodedKeySpecobject 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- encodedKeyor- algorithmis null.
- IllegalArgumentException- if- algorithmis the empty string- ""

Method Detail- 
getAlgorithmpublic 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
 
 - 
getEncodedpublic byte[] getEncoded() Returns the encoded key.- Returns:
- the encoded key. Returns a new array each time this method is called.
 
 - 
getFormatpublic 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 (seeKeyFactory) into this key specification (or a subclass of it),getFormatcalled on the opaque key returns the same value as thegetFormatmethod of this key specification.- Returns:
- a string representation of the encoding format.
