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.

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).
