About This Tool

  • Computation happens entirely in the browser; nothing you enter or upload is sent to a server.
  • SHA-1, SHA-256, SHA-384, and SHA-512 are supported. MD5 cannot be computed because the browser's standard API (Web Crypto API) doesn't support it.
  • When verifying file integrity, using SHA-256 or a stronger algorithm is recommended.
