Free online hash generator. Generate MD5, SHA-256, and SHA-512 hashes instantly from any text input. Secure client-side hashing using Web Crypto API. Perfect for developers, file integrity checks, and password hashing.
Type or paste the text you want to hash into the input field. You can hash any string of text.
Select the hash algorithm — MD5, SHA-256, or SHA-512. SHA-256 is recommended for most purposes.
Click Generate Hash to compute the hash. Click the result to copy it to your clipboard instantly.
Q: What is a hash function?
A: A hash function takes input data and produces a fixed-size string of characters. It's deterministic (same input = same output) and one-way (can't reverse).
Q: Which algorithm should I use?
A: SHA-256 is recommended for most purposes. MD5 is faster but cryptographically broken — avoid for security. SHA-512 offers the strongest security.
Q: Is my data secure?
A: Yes! All hashing happens client-side in your browser using the Web Crypto API. Your data never leaves your device.
