    crypto: testmgr - add test vectors for blake2b · a1afe274
    David Sterba authored
    Test vectors for blake2b with various digest sizes. As the algorithm is
    the same up to the digest calculation, the key and input data length is
    distributed in a way that tests all combinanions of the two over the
    digest sizes.
    
    Based on the suggestion from Eric, the following input sizes are tested
    [0, 1, 7, 15, 64, 247, 256], where blake2b blocksize is 128, so the
    padded and the non-padded input buffers are tested.

             ---------------------------------------------------
    len=0   | klen=0       klen=1       klen=32      klen=64
    len=1   | klen=32      klen=64      klen=0       klen=1
    len=7   | klen=64      klen=0       klen=1       klen=32
    len=15  | klen=1       klen=32      klen=64      klen=0
    len=64  | klen=0       klen=1       klen=32      klen=64
    len=247 | klen=32      klen=64      klen=0       klen=1
    len=256 | klen=64      klen=0       klen=1       klen=32
    
    Where key:
    
    - klen=0: empty key
    - klen=1: 1 byte value 0x42, 'B'
    - klen=32: first 32 bytes of the default key, sequence 00..1f
    - klen=64: default key, sequence 00..3f
    
    The unkeyed vectors are ordered before keyed, as this is required by
    testmgr.
