Hash Generator (MD5/SHA-1/SHA-256)
How it works: Generates cryptographic hashes using the Web Crypto API. SHA-256 is recommended for most use cases. Hashing is one-way—you cannot reverse a hash hashing (though use proper password hashing algorithms like bcrypt for production).
Overview
Generate cryptographic hashes for text or files with our Hash Generator. Compute MD5, SHA-1, or SHA-256 hashes entirely in your browser with no uploads required. Perfect for verifying file integrity, checking download authenticity, generating checksums, or creating unique identifiers. Simply paste text or select a file, choose your hash algorithm, and get the hexadecimal digest instantly. The tool uses the Web Crypto API for SHA algorithms and a lightweight library for MD5, ensuring fast and accurate results. All processing happens locally—your files and text never leave your device. Ideal for developers, system administrators, security professionals, or anyone needing to verify data integrity. Copy the hash output with one click for easy comparison or documentation.

FAQ
Do you upload files to a server?
No. Hashing happens locally via Web Crypto (MD5 via a tiny library).
Which hash should I pick?
SHA-256 is strongest here. MD5/SHA-1 are legacy and not collision-safe.
What's the output format?
We show a lowercase hexadecimal digest.
