My question is this: Are there any crypto hash implementations beyond 512 bits of output?
Could you give me the link?
Thank you so much for your time.
Greetings.
You can use any hash function with a stream cipher or block cipher in streaming mode like CTR/OFB to produce arbitrary length output beyond 512 bits.
Another method is using extendable-output functions (XOFs). XOF is a hash function that its output can be extended to any length. Keccak (SHA-3), Skein and BLAKE3 have extendable output mode.
There are many implementations of SHAKE128/SHAKE256 (SHA-3's XOF).
