ℹ️ About Hashing

Cryptographic hash functions are one-way — you cannot reverse a hash back to the original text. SHA-256 and SHA-512 are used in security-critical applications. SHA-1 is considered weak and should not be used for security purposes. All hashing happens locally in your browser using the Web Crypto API.
