Hash Generator

Generate SHA-1, SHA-256, SHA-384, and SHA-512 hashes from text.

About Hash Functions

Cryptographic hash functions produce a fixed-size output from any input. They are one-way functions - you cannot reverse a hash to get the original input.

SHA-1

160 bits - Legacy, not recommended for security

SHA-256

256 bits - Widely used, secure

SHA-384

384 bits - High security

SHA-512

512 bits - Maximum security
