Hello Herbert (cc: list), This is an attempt at implementing LRW for the new blockcipher API. Please review, test and comment. I intend to implement ABL also (arbitrary block length), an unencumbered wide block cipher mode (it is based on GMC (Galois/Counter Mode) which is explicitly claimed to be patent free and has the same creators). The mode has been dropped by its creators (I don't know why) and is not formally publised, see: http://grouper.ieee.org/groups/1619/email/pdf00005.pdf http://grouper.ieee.org/groups/1619/email/rtf00000.rtf It fulfills the same function as the patent-encumbered EME, CMC and XCB.
