Algorithm Overview

SHA-1

160-bit hash, cryptographically broken

SHA-256

256-bit hash, widely used and secure

SHA-384

384-bit hash, truncated SHA-512

SHA-512

512-bit hash, highest security

Use Cases

  • • File integrity - Verify downloads
  • • Password storage - Use with salt
  • • Digital signatures - Cryptographic proofs
  • • Blockchain - Bitcoin uses SHA-256
  • • Checksums - Data validation
  • • Duplicate detection - Content matching
Security Warning:
SHA-1 is cryptographically broken and should not be used for security purposes. Use SHA-256 or higher for secure applications. All hashing is done client-side using the Web Crypto API.
