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
