What is SHA-256 and what is it for?
SHA-256 (Secure Hash Algorithm 256) is part of the SHA-2 family and produces a 256-bit hash, represented by 64 hexadecimal characters. It is considered secure for cryptographic use and has no known collision vulnerabilities.
It is widely used in SSL/TLS certificates, digital signatures, blockchain (including Bitcoin), file integrity verification and secure password storage (with salt). It replaced MD5 and SHA-1 in most modern systems.
This tool uses the Web Crypto API built into modern browsers — the calculation is done locally, without network traffic.
