      "This package provides a practical incremental and one-pass,
pure API to the SHA-512 hash algorithm (including HMAC support) with
performance close to the fastest implementations available in other
languages.  The implementation is made in C with a haskell FFI wrapper
that hides the C implementation.  NOTE: This package has been forked
off cryptohash-0.11.7 because the cryptohash package has been
deprecated and so this package continues to satisfy the need for a
lightweight package providing the SHA512 hash algorithm without any
dependencies on packages other than base and bytestring.  Consequently,
this package can be used as a drop-in replacement for cryptohash's
\"Crypto.Hash.SHA512\" module, though with a clearly smaller
footprint.")

Hi N0lim,

Nice.

Could you turn it into a patch for Guix proper?  Please take a look at
<https://guix.gnu.org/manual/devel/en/html_node/Submitting-Patches.html>
and do ask here or on #guix on IRC if anything’s unclear.

In particular:

> (define-module (n0lim ghc-cryptohash-sha512)

… packages in Guix are in the (gnu packages …) name space.  You’ll find
that one of the gnu/packages/haskell*.scm files is probably suitable for
this package.

Thanks in advance!

Ludo’.
