构造器详细资料

EncodedKeySpec

public EncodedKeySpec(byte[] encodedKey)

Creates a new EncodedKeySpec with the given encoded key.

参数:

encodedKey - the encoded key. The contents of the array are copied to protect against subsequent modification.

抛出:

NullPointerException - if encodedKey is null.

方法详细资料

getEncoded

public byte[] getEncoded()

Returns the encoded key.

返回:

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.

返回:

a string representation of the encoding format.
