Crypto.Hash.Algorithms

Class representing hashing algorithms.

The interface presented here is update in place and lowlevel. the Hash module takes care of hidding the mutable interface properly.

SHAKE128 (128 bits) extendable output function. Supports an arbitrary digest size, to be specified as a type parameter of kind Nat.

Note: outputs from SHAKE128 n and SHAKE128 m for the same input are correlated (one being a prefix of the other). Results are unrelated to SHAKE256 results.

SHAKE256 (256 bits) extendable output function. Supports an arbitrary digest size, to be specified as a type parameter of kind Nat.

Note: outputs from SHAKE256 n and SHAKE256 m for the same input are correlated (one being a prefix of the other). Results are unrelated to SHAKE128 results.

Fast cryptographic hash.

It is especially known to target 64bits architectures.

Known supported digest sizes:

• Blake2b 160

• Blake2b 224

• Blake2b 256

• Blake2b 384

• Blake2b 512

Fast and secure alternative to SHA1 and HMAC-SHA1

It is espacially known to target 32bits architectures.

Known supported digest sizes:

• Blake2s 160

• Blake2s 224

• Blake2s 256

Skein256 with the digest size given as a type parameter of kind Nat, in bits. Skein256 256 is Skein256_256; the sizes with a type of their own above are there for their names, and this one also takes the sizes that have none.

A size that is not a whole number of bytes is rounded up to the next one, as the implementation underneath does.

The output is produced in counter mode, a block of it per Threefish call, so one large digest is a good deal cheaper than the same number of bytes taken from repeated small ones: on an Apple M4, 512 KiB arrives at 947 MB/s in one digest against 172 MB/s as 8192 separate Skein256_256 ones.

Note the digest size goes into the configuration block, so it changes the value the message is hashed from: a longer digest is not an extension of a shorter one. That is the opposite of how SHAKE128 behaves.
