description = """
|
|
When used in conjunction with the Hash-based Message Authentication Code (HMAC),
|
|
the BLAKE2b and BLAKE2s implementations in `blake2` crate versions prior to
|
|
v0.8.1 used an incorrect block size (32-bytes instead of 64-bytes for BLAKE2s,
|
|
and 64-bytes instead of 128-bytes for BLAKE2b), causing them to miscompute the
|
|
`MacResult`.
|
|
|
|
The v0.8.1 release of the `blake2` crate uses the correct block sizes.
|
|
|
|
Note that this advisory only impacts usage of BLAKE2 with HMAC, and does not
|
|
impact `Digest` functionality.
