Hash Generator
Compute cryptographic hash digests for any text input. Supports MD5, SHA-1, SHA-256, SHA-384, and SHA-512. Results are shown in hex and base64. All computation happens in your browser.
Hash Algorithms
MD5: 128-bit (16 bytes) — NOT cryptographically secure, use for checksums only SHA-1: 160-bit (20 bytes) — deprecated for security SHA-256: 256-bit (32 bytes) — recommended SHA-512: 512-bit (64 bytes) — highest security
Examples
"hello world"
Result: MD5: 5eb63bbbe01eeed093cb22bb8f5acdc3 SHA-256: b94d27b99...
Same input always produces same hash (deterministic).
Frequently Asked Questions
Can I reverse a hash to get the original text?
No. Hash functions are one-way. There is no way to reverse a hash to the original input (without brute force or rainbow tables for weak inputs).
Should I use MD5 for passwords?
Never. MD5 is broken for password hashing. Use bcrypt, Argon2, or PBKDF2 for passwords. MD5 is only safe for file integrity checksums.
