About Cryptographic Hashes

100% Client-Side & Private: All hash generation happens locally in your browser using the Web Crypto API. Nothing is sent to any server.

What are Hash Functions? One-way cryptographic functions that convert data of any size into a fixed-size string. You cannot reverse a hash to get the original data.

MD5: 128-bit hash. Fast but cryptographically broken - NOT recommended for security purposes. Use only for checksums.

SHA-1: 160-bit hash. Deprecated for security due to collision vulnerabilities. Avoid for new applications.

SHA-256: 256-bit hash from SHA-2 family. Currently recommended standard for most security applications including SSL certificates and blockchain.

SHA-384 & SHA-512: Stronger variants (384-bit & 512-bit) from SHA-2 family for applications requiring higher security margins.

Use Cases: File integrity verification, digital signatures, blockchain, checksums, data deduplication, API keys.

Important: Never use plain hashes for password storage - always use dedicated password hashing algorithms like bcrypt, scrypt, or Argon2 with proper salting.
