HashCalc
Hash CRC and HMAC calculator for Windows
HashCalc is a focused Windows utility for checking file integrity and generating cryptographic values from files, plain text, and hexadecimal strings. Its main purpose is simple: select an input, choose the calculation type, and compare the result with a known value, such as a checksum published by a software developer.
The program supports two main modes, Hash/Checksum and HMAC, giving it more flexibility than a basic checksum viewer.
