About Cryptographic Hashes

Cryptographic hash functions generate fixed-size outputs from variable-size inputs. They're one-way functions used for data integrity verification, password storage, and digital signatures.

  • SHA-256: Part of SHA-2 family, produces 256-bit (64 hex characters) hash
  • SHA-1: Produces 160-bit (40 hex characters) hash (deprecated for security)

FAQ

A hash is a fixed-size string generated from input data. The same input always produces the same hash, but it's computationally infeasible to reverse the process.

Use SHA-256 for security-critical applications. SHA-1 is deprecated due to collision vulnerabilities but still used for non-security purposes like Git commits.

Yes! All hashing happens in your browser using the Web Crypto API. Your data never leaves your device.
