📖 Hash Algorithm Information

MD5

128-bit hash, 32 hex characters. Not cryptographically secure - use for checksums only.

SHA-1

160-bit hash, 40 hex characters. Deprecated - vulnerable to collision attacks.

SHA-256

256-bit hash, 64 hex characters. Recommended - secure for most applications.

SHA-512

512-bit hash, 128 hex characters. Very secure - for high-security applications.

SHA-3

Keccak algorithm, 256-bit output. Latest standard - modern alternative.

HMAC

Keyed-Hash Message Authentication Code. Authenticated hash - requires secret key.

⚡ Quick Examples

💡 Pro Tip: Use SHA-256 or SHA-512 for password hashing (with salt). Use HMAC for API authentication. MD5/SHA-1 are fine for file integrity checks only.

Free Online Hash Generator – Cryptographic Hash Tool

Generate secure cryptographic hashes using MD5, SHA-1, SHA-256, SHA-512, SHA-3, RIPEMD-160, and HMAC algorithms. Perfect for password hashing, file integrity verification, digital signatures, and API authentication. All processing happens locally in your browser — 100% private and secure.

Use Cases

  • Password Storage: Hash passwords securely (always use salt + SHA-256/SHA-512)
  • File Integrity: Verify file hasn't been corrupted or tampered with
  • API Authentication: Generate HMAC signatures for API requests
  • Data Deduplication: Create unique identifiers for data blocks
  • Digital Signatures: Hash documents before signing
  • Checksums: Verify data integrity during transfers
