#️⃣ Hash Generator

Our free Hash Generator computes cryptographic hashes for any text input using MD5, SHA-1, SHA-256, SHA-384, and SHA-512. All computation happens in your browser — no data is ever sent to a server. Essential for developers, security professionals, and anyone verifying data integrity.

Example: The string 'Hello World' produces: MD5 = b10a8db16... (32 chars), SHA-1 = 0a4d55a8d... (40 chars), SHA-256 = a591a6d40... (64 chars), SHA-512 = 861844d67... (128 chars). Each algorithm produces a different length and value for the same input.

Use cases: (1) File integrity — verify downloaded files against published checksums. (2) Password storage — hash with salt (bcrypt/argon2 recommended over raw SHA). (3) Duplicate detection — hash content to find duplicates. (4) API development — verify request integrity with HMAC.

Security tips: MD5 and SHA-1 are cryptographically broken — don't use for security. SHA-256 is the minimum standard today. For passwords, use argon2, bcrypt, or PBKDF2 — not raw SHA-256. For file verification, SHA-256 is the industry standard (not MD5).

Related: Use with our Base64 Encoder for binary-to-text encoding. The Password Generator creates strong passwords to hash. The JSON Formatter structures data before hashing. The Text Cleaner normalizes input for consistent checksums.

All major operating systems include hashing tools: Linux/macOS: shasum -a 256 file, md5 file. Windows: certutil -hashfile file SHA256. Our browser tool provides the same functionality without the terminal — just paste and hash.
