About Hash Generator
A cryptographic hash function converts any input into a fixed-length string (the hash). Even a single character change in the input produces a completely different hash. Common uses include verifying file integrity, storing passwords securely, and generating checksums. SHA-256 and SHA-512 use the browser's native Web Crypto API for fast, secure hashing. MD5 and SHA-1 are provided for legacy compatibility — they are not recommended for security-sensitive use.
