pub fn blake2b<const LEN: usize>(payload: &[u8], key: &[u8]) -> [u8; LEN]Expand description
BLAKE2b
Note that the output can not be more than 64. If the requested output is larger than 64, the 64-byte output value is written to the first 64 bytes of the output.
The payload and key are truncated at 2^32 bytes.
The key may be an empty slice.
