About File Hashes

  • MD5: 128-bit hash. Fast but not cryptographically secure. Good for file integrity checks.
  • SHA-1: 160-bit hash. Deprecated for security, but still used for compatibility.
  • SHA-256: 256-bit hash. Recommended for most use cases. Cryptographically secure.
  • SHA-384: 384-bit hash. Higher security than SHA-256.
  • SHA-512: 512-bit hash. Highest security. Used for critical applications.

Privacy: All hash generation happens in your browser using the Web Crypto API. Your files never leave your device.

Common Use Cases for File Hashes

Verifying downloads: Software developers often publish SHA-256 checksums alongside their releases. After downloading, generate the hash of your local copy and compare it to the published value. If they match, your download is intact and has not been tampered with.

Detecting duplicate files: Two files with identical hashes are guaranteed to have identical content, regardless of filename. This makes hash comparison useful for deduplication in large file collections.

Digital forensics and compliance: In legal and regulatory contexts, file hashes serve as digital fingerprints that prove a file has not been altered since a specific point in time.

How FileShot Keeps This Private

All hash calculations run entirely in your browser using the Web Crypto API. Your file data never leaves your device ? not even temporarily. This means there is zero risk of your files being intercepted, logged, or stored during the hashing process. No account is required and no data is collected.
