Online Hash Generator
Generate MD5, SHA-1, SHA-256, and SHA-512 hashes from text or files. 100% private, all processing in your browser
Frequently Asked Questions
MD5 outputs 128 bits and is fast but proven vulnerable to collisions; SHA-1 outputs 160 bits with lower security; SHA-256 and SHA-512 belong to the SHA-2 family with high security, recommended for security use.
No. All hash computation is done locally in your browser. Your text and file data never leave your device, fully protecting your privacy.
Both text input and file upload are supported. Text input computes the hash in real time, while file upload generates a hash of the entire file content.
Not recommended. MD5 is proven vulnerable to collisions and is unsuitable for password storage or other security scenarios. Use SHA-256 or stronger; for password storage, use a dedicated slow hash algorithm with a salt.
Currently it handles a single text or file at a time. For batch processing, enter text or select files one at a time.
