Free MD5 Hash Generator
Generate MD5 hash from any text string. Free online MD5 hash generator. Works entirely in your browser with no sign-up required.
Hash Generator
Generate and verify cryptographic hashes (MD5, SHA-1, SHA-256, SHA-384, SHA-512) from text or files with HMAC, batch, and chain support.
Algorithm Selection
Input
SHA-256 Hash
Enter text or upload a file to generate hash
Checksum Verification
Paste a known hash below to compare with the generated hash and verify integrity.
Algorithm Reference
128-bit hash. Fast but cryptographically broken since 2004. Collision attacks are trivial on modern hardware.
Speed: Very Fast
Output: 32 hex chars
Use cases: Non-security checksums, deduplication, legacy systems.
160-bit hash. Deprecated for security after the SHAttered collision in 2017.
Speed: Fast
Output: 40 hex chars
Use cases: Git commit hashes (legacy), non-security fingerprints.
256-bit hash from the SHA-2 family. The most widely used secure hash today.
Speed: Moderate
Output: 64 hex chars
Use cases: Digital signatures, TLS certificates, blockchain, password hashing (with salt).
384-bit truncated variant of SHA-512. Offers extra margin against length-extension attacks.
Speed: Moderate
Output: 96 hex chars
Use cases: Government/military standards (Suite B), TLS cipher suites.
512-bit hash. Fastest SHA-2 variant on 64-bit CPUs. Maximum security margin.
Speed: Moderate (fast on 64-bit)
Output: 128 hex chars
Use cases: Large file integrity, high-security applications, password storage.

Security Tips
- Never use MD5 or SHA-1 for password hashing or security-critical applications.
- For passwords, use dedicated algorithms like bcrypt, scrypt, or Argon2 (not available in browser).
- Always use HMAC when authenticating messages to prevent length-extension attacks.
- SHA-256 is the recommended minimum for general-purpose cryptographic hashing.
- All hashing is performed locally in your browser. No data is sent to any server.
