About:
Sha3sum provides a comprehensive suite of command-line utilities for computing checksums using the Keccak family of algorithms. It supports the complete SHA-3 standard, as well as SHAKE and RawSHAKE for variable-length and raw hashing applications. This tool is essential for developers and security professionals needing to verify data integrity using modern, secure hashing primitives.
Key Features:
  • Implements SHA-3, Keccak, SHAKE, and RawSHAKE algorithms
  • Provides both a unified sha3sum command and individual algorithm utilities
  • Strict adherence to NIST FIPS 202 standards
  • High-performance C implementation with libkeccak dependency
Use Cases:
  • Verifying file integrity and authenticity after download
  • Generating secure checksums for archival and data validation
  • Creating custom-length hashes for cryptographic applications using SHAKE
Alternatives:
  • openssl – OpenSSL includes sha3 commands but Sha3sum is a dedicated, lightweight utility focused solely on Keccak-family hashing.
