Zest hash, 4096 bit block hash:

Features of this crate:

Contains an implementation of zest4096, a fast block hash based off of chacha20, as well as helper functions which uses it.

Contains a fully functional CSPRNG with associated tools, Symmetric 4096 bit encryption (using the hash in GCM mode), Digests of byte slices, etc.

Disclaimer:

The security level of this hash function, and associated tools have not been tested. Use at your own risk.

Hashes of 64 element arrays of identical 64 bit values (such as all 0, all 1, etc) will result in undesireable output.
