salsa20_set_iv: Deleted size argument.

parent 588e0e8f
2012-03-31 Niels Möller <nisse@lysator.liu.se>
* salsa20.c: (salsa20_set_iv): Deleted size argument, only one
size allowed.
* nettle-internal.c (salsa20_set_key_hack): Updated salsa20_set_iv
call.
* testsuite/salsa20-test.c (test_salsa20): Deleted iv_length
argument, updated all calls.
* salsa20.h (SALSA20_BLOCK_SIZE): New constant.
(_SALSA20_INPUT_LENGTH): New constant.
* salsa20.c: Use these constants.
