About Hash Generator
The Online Hash Generator computes SHA-1, SHA-256, SHA-384, and SHA-512 cryptographic hashes for any text input, entirely within your browser. No data is ever transmitted to a server — your text stays completely private. This tool uses the browser’s built-in Web Crypto API (
Cryptographic hash functions are one-way mathematical functions that convert input data of any size into a fixed-length string of hexadecimal characters. The same input always produces the same hash, but even a single character change produces a completely different hash. This property makes them ideal for data integrity verification.
Supported algorithms: SHA-1 (40 chars), SHA-256 (64 chars), SHA-384 (96 chars), SHA-512 (128 chars). Note: SHA-1 is considered cryptographically weak for security applications — use SHA-256 or higher for security-sensitive purposes.
