Generate MD5, SHA-1, SHA-256, and SHA-512 hashes from any text
This hash generator computes cryptographic hash values for any text string using MD5, SHA-1, SHA-256, and SHA-512 algorithms. All computation happens entirely in your browser using the Web Crypto API (for SHA algorithms) and a JavaScript implementation of MD5 — no data is transmitted to any server.
Hashes are one-way functions that produce a fixed-length output from any input. They are commonly used for verifying data integrity, storing passwords securely, and creating unique identifiers.
Type or paste any text into the input field and click "Generate Hashes". The MD5, SHA-1, SHA-256, and SHA-512 hash values will be displayed in labeled boxes. Click the "Copy" button next to any hash to copy it to your clipboard.
MD5 produces 128-bit hashes and is considered cryptographically broken for security purposes, but is still used for checksums. SHA-1 (160-bit) is also deprecated for security use. SHA-256 and SHA-512 are part of the SHA-2 family and are currently considered secure. SHA-256 produces a 256-bit hash and SHA-512 produces a 512-bit hash.
No. This tool runs entirely client-side in your browser. SHA hashes are computed using the built-in Web Crypto API (SubtleCrypto), and MD5 is computed using a JavaScript implementation. Your text never leaves your computer, making this safe for sensitive data.
