Checksum verify with GtkHash

GtkHash is a desktop utility for computing message digests or checksums. Most well-known hash functions are supported, including MD5, SHA1, SHA2 (SHA256/SHA512), SHA3 and BLAKE2.

It's designed to be an easy to use, graphical alternative to command-line tools such as md5sum.
