How to Install and Uninstall ghc-cryptohash-sha256 Package on openSuSE Tumbleweed

Information for package ghc-cryptohash-sha256:
----------------------------------------------
Repository : openSUSE-Tumbleweed-Oss
Name : ghc-cryptohash-sha256
Version : 0.11.102.1-4.5
Arch : x86_64
Vendor : openSUSE
Installed Size : 73.8 KiB
Installed : No
Status : not installed
Source package : ghc-cryptohash-sha256-0.11.102.1-4.5.src
Upstream URL : https://hackage.haskell.org/package/cryptohash-sha256
Summary : Fast, pure and practical SHA-256 implementation
Description :
A practical incremental and one-pass, pure API to the [SHA-256 cryptographic
hash algorithm](https://en.wikipedia.org/wiki/SHA-2) according to [FIPS
180-4](http://dx.doi.org/10.6028/NIST.FIPS.180-4) with performance close to the
fastest implementations available in other languages.
The core SHA-256 algorithm is implemented in C and is thus expected to be as
fast as the standard [sha256sum(1)
tool](https://linux.die.net/man/1/sha256sum); for instance, on an /Intel Core
i7-3770/ at 3.40GHz this implementation can compute a SHA-256 hash over 230 MiB
of data in under one second. (If, instead, you require a pure Haskell
implementation and performance is secondary, please refer to the [SHA
package](https://hackage.haskell.org/package/SHA).)
Additionally, this package provides support for
- HMAC-SHA-256: SHA-256-based [Hashed Message Authentication
Codes](https://en.wikipedia.org/wiki/HMAC) (HMAC) - HKDF-SHA-256:
[HMAC-SHA-256-based Key Derivation
Function](https://en.wikipedia.org/wiki/HKDF) (HKDF)
conforming to [RFC6234](https://tools.ietf.org/html/rfc6234),
[RFC4231](https://tools.ietf.org/html/rfc4231),
[RFC5869](https://tools.ietf.org/html/rfc5869), et al..
=== Relationship to the 'cryptohash' package and its API
This package has been originally a fork of 'cryptohash-0.11.7' because the
'cryptohash' package had been deprecated and so this package continues to
satisfy the need for a lightweight package providing the SHA-256 hash algorithm
without any dependencies on packages other than 'base' and 'bytestring'.
The API exposed by 'cryptohash-sha256-0.11.*''s "Crypto.Hash.SHA256" module is
guaranteed to remain a compatible superset of the API provided by the
'cryptohash-0.11.7''s module of the same name.
Consequently, this package is designed to be used as a drop-in replacement for
'cryptohash-0.11.7''s "Crypto.Hash.SHA256" module, though with a [clearly
smaller footprint by almost 3 orders of
magnitude](https://www.reddit.com/r/haskell/comments/5lxv75/psa_please_use_unique_module_names_when_uploading/dbzegx3/).
