Hash Generator

About the Hash Generator

The Hash Generator computes SHA-1, SHA-256, SHA-384, and SHA-512 cryptographic hashes for any input string. Type or paste your text and instantly see all four hash values. Hash generation uses the browser's native Web Crypto API — no external libraries required.

Cryptographic hash functions produce a fixed-length digest from any input. The same input always produces the same hash; even a one-character change produces a completely different output. Hashes are used to verify file integrity (checksums), store passwords securely, generate content-addressable identifiers (like Git commit hashes), and create message authentication codes (MACs).

SHA-256 is currently the most widely used hash algorithm and is recommended for new applications. SHA-1 is provided for compatibility with legacy systems but is no longer considered cryptographically secure for new use cases. All hashing runs entirely in your browser using the Web Crypto API — your input data is never transmitted.
