arb_hash_rs

Arbitrary block length hash function, potentially cryptographically secure. Passes BigCrush

features = ["block"]

• resize_block (Runtime funtion for truncating a block with zeros)
• const_resize_block (Const funtion for truncating a compile-time known sized block with zeros)
• pad_input (Runtime function for padding bytes to ISO/IEC 7816-4 standard)
• xor_blocks (Const function for mod-2 addition of two blocks)
• inc_block (Const function for Mod-2 addition of two blocks)

features = ["digest"]

• arb_digest (Runtime function for digest computation, running in a single thread)
• arb_digest_const (Const funtion for digest computation, running during compile time)

features = ["parallel", "digest"]

• arg_digest_parallel (Parallel computation of digest of byte array)

features = ["hash"]

• arb_hash (Const funtion for hashing some input byte array)

Notes: Rust seems to be lacking compile time arithmetic with const generics, so there are some limitations to what I can do. The funtion arb_digest_const should really allow a byte array instead of array of blocks to be input, however that would require me to split that into blocks, which I couldn't find a way to do with const generics. Anyways, if there is a flaw or bug in this library, please let me know so I can fix said bug immediately. Happy hashing!
