Online MD5, SHA-1, SHA-256 Hash Generator
Generate cryptographic hashes for any text string or file. Supports SHA-1, SHA-256, SHA-384, and SHA-512.
Use the built-in Verify tool to compare a file's checksum against a known hash to ensure data integrity and detect tampering.
Password Hashing
Developers use hashes to store passwords securely. A hash is a one-way function; you can turn "password123" into a hash, but you cannot reverse the hash back to the password.
File Checksums
When downloading software (like Linux ISOs), developers provide a SHA-256 hash. Hashing your downloaded file and comparing it ensures the file wasn't corrupted or hacked during download.
Client-Side Only
We use the Web Crypto API. Your files and passwords are processed entirely in your browser's memory. No data is ever sent to our servers.
Hashing Algorithms Guide
SHA-1 (160-bit)
Older and faster, but considered cryptographically broken due to collision vulnerabilities. Still used for checksums (Git) but not for security.
SHA-256 (256-bit)
The industry standard. Used by Bitcoin, SSL certificates, and most secure applications today. It offers a perfect balance of speed and security.
