APK SHA-256 Verifier
Private, browser-based SHA-256 checksum calculator for APK files
APK SHA-256 Verifier calculates and compares SHA-256 checksums entirely in the browser. Selected files remain on the device and are processed in 4 MB chunks; no upload or account is required. Paste an expected 64-character digest to receive match, difference, or invalid-format feedback, or compare two existing hashes without loading a file. A matching checksum confirms byte-for-byte identity with the reference, but it does not prove an APK is safe or authentic. The project includes deterministic tests, privacy and security documentation, and is released under the MIT License. -

ReHash - A Versatile Hash Calculator
Console-based Hash Calculator, written by D. Reichl
Author's words: "ReHash is an easy-to-use console-based hash calculation tool written in C++. It supports many algorithms and output formats and it can be fully configured using some of the many command-line arguments which can be passed to the tool." This is a nice, straightforward hash sum calculator. Since the files from the original project are very old and there seems to be no maintainance any more, I've "forked" the project here, updated the source and VC++ project files a bit, and provide fresh-built binaries for Win32. Original project: https://sourceforge.net/projects/rehash Copyright and License do of course remain the same. -

file digest
A command-line utility for calculating and verifying file checksums.
Digest is a command-line utility which can be used to calculate and verify checksums of any files, similar to md5sum or RHash, but using modern hash algorithms. Supported algorithms: BLAKE, BLAKE2, Grøstl, JH, Kupyna, MD5, SHA-1, SHA-2, SHA-3, Skein, SM3, Streebog, Whirlpool. Usage: digest [-c] <algorithm> <filename(s)> For example, if you want to calculate the checksums using skein512/256 algorithm, use this command: digest skein512/256 * > checksums.skein To verify the checksums: digest -c skein512/256 checksums.skein You can get a full list of supported algorithms and test the performance of different algorithms on your PC using the command: digest test <iterations> <filename> This will calculate hash sum of <filename> multiple times (number of times is specified by <iterations>) and output the results with precise timings. Note: if you have a 64-bit operating system, use 64-bit binary of the utility, because it is significantly faster for large files. -
