Generate MD5, SHA-1, SHA-256, and SHA-512 hashes instantly in your browser. Live output as you type — no submit needed. 100% client-side and private.
Four algorithms, live output, compare mode — all running privately in your browser.
Generate MD5 checksums for legacy system compatibility, file integrity checks, and non-security identifiers.
Industry-standard cryptographic hash functions. SHA-256 and SHA-512 are suitable for data integrity and modern security use.
All four hash outputs update in real time as you type. No submit button, no waiting — instant feedback.
Enter two inputs side by side and instantly see which hashes match and which differ — per algorithm.
Copy any single hash to your clipboard with one click. Each algorithm row has its own copy button.
MD5 runs via a pure JS implementation; SHA hashes use the built-in Web Crypto API. No data leaves your browser.
MD5 produces a 128-bit (32 hex char) hash and is considered cryptographically broken — avoid it for security. SHA-256 produces a 256-bit (64 hex char) hash and is still considered secure for data integrity, digital signatures, and certificate fingerprints. For new work, always prefer SHA-256 or SHA-512.
No. MD5, SHA-1, SHA-256, and SHA-512 are general-purpose hash functions — they are fast by design, which makes them easy to brute-force for passwords. For password storage, use a slow, purpose-built algorithm like bcrypt, scrypt, or Argon2, which add computational cost and salt automatically.
SHA-512 produces a 512-bit (128 hex char) digest. It is used where maximum collision resistance is needed: high-security digital signatures, certificate chains, long-term archiving, and HMAC-SHA-512 in JWT tokens. It is also faster than SHA-256 on 64-bit processors due to its use of 64-bit word operations.
From hashing and JWT auth to full security audits — we help teams ship secure, production-ready products.
