Creates a DESedeKeySpec object using the first 24 bytes in
key
, beginning at offset
inclusive,
as the key material for the DES-EDE key.
The bytes that constitute the DES-EDE key are those between
key[offset]
and key[offset+23]
inclusive.
key | the buffer with the DES-EDE key material. The first
24 bytes of the buffer beginning at offset inclusive
are copied to protect against subsequent modification. | |
offset | the offset in key , where the DES-EDE key
material starts. |
NullPointerException | if key is null. | |
InvalidKeyException | if the given key material, starting at
offset inclusive, is shorter than 24 bytes |
