C# CRC-16 Checksum Algorithm

Implementation of fletcher-16, fletcher-32, and fletcher-64 checksums in Python3 for working with string and bytes data

Generate SHA1, SHA-224, SHA-256, SHA-384, SHA-512, SHA-3-224, SHA-3-256, SHA-3-384, SHA-3-512 and MD5 checksums/hash values for a given file.

nHash is a lightweight and easy-to-use hashing tool for Windows and Linux that allows users to quickly and securely generate cryptographic hash values for files and text. It supports a variety of popular hash algorithms, including MD5, SHA-1, SHA-256, and more, making it an essential tool for verifying file integrity and ensuring data privacy.

A Python CRC library for calculation and C-code generation

CRC16-MODBUS Checksum calculator, Kotlin

A simple utility that calculates the CRC-32 checksum for each of the given files or for data from standard input. It aims to work in the same way as the md5sum utility.

Functions for computing checksums

Fast, hardware-accelerated CRC calculation in PHP for all known CRC-32 and CRC-64 variants using SIMD intrinsics, which can exceed 100GiB/s for CRC-32, and 50GiB/s for CRC-64, on modern systems. Much faster (up to >200X) than PHP's internals.
