Generate MD5, SHA-1, SHA-256 and SHA-512 hashes from text or files. Instant results — everything runs in your browser, nothing is uploaded.
| Algorithm | Output | Bits | Status |
|---|---|---|---|
| MD5 | 32 hex chars | 128 | Broken (use for checksums only) |
| SHA-1 | 40 hex chars | 160 | Deprecated (avoid for security) |
| SHA-256 | 64 hex chars | 256 | Secure ✓ |
| SHA-512 | 128 hex chars | 512 | Secure ✓ |
MD5 (Message Digest 5) produces a 128-bit (32-character hex) hash. It is fast and widely used for file integrity checks and checksums, but it is not suitable for passwords or security applications due to known collision vulnerabilities.
SHA-1 produces a 160-bit (40-character) hash and is now deprecated. SHA-256 (256-bit, 64 chars) and SHA-512 (512-bit, 128 chars) are part of the SHA-2 family and are considered cryptographically secure. SHA-512 offers a larger output and may be faster on 64-bit systems.
No. MD5 is not safe for storing passwords — preimage attacks and rainbow tables make it trivial to reverse. Use bcrypt, Argon2 or PBKDF2 for passwords. MD5 is still fine for non-security purposes like file checksums.
No. All hashing runs entirely in your browser using the Web Crypto API (for SHA algorithms) and a pure JavaScript MD5 implementation. Your text and files never leave your device.
