GtkHash is described as 'Currently supported hash functions include CRC32, ADLER32, GOST, MD2, MD4, MD5, MD6, SHA1, SHA2, SHA3, RIPEMD, HAVAL, TIGER, WHIRLPOOL and BLAKE2' and is an app. There are more than 25 alternatives to GtkHash for a variety of platforms, including Windows, Linux, Mac, BSD and Android apps. The best GtkHash alternative is NanaZip, which is both free and Open Source. Other great apps like GtkHash are HashCheck Shell Extension, OpenHashTab, Collision and HashMyFiles.
MD5summer is an application for Microsoft Windows 9x, NT, ME, 2000 and XP which generates and verifies md5 checksums. Its output file is compatible with the output of the Linux GNU MD5Sum and it will also read Linux generated files. MD5summer is written in Borland Delphi 7.
