Encode or decode URLs to handle special characters, ensuring links are correctly transmitted over the network.

Convert characters to HTML entities (like &) or back to plain text. Useful for web security and character escaping.

Convert text to Unicode escape sequences (e.g., \uXXXX) and vice versa for internationalization support.

Transform text data into Base64 format or decode Base64 strings back to original plain text.

Encrypt and decrypt text locally using symmetric (AES-GCM) or asymmetric (RSA-OAEP) algorithms.

Generate and verify digital signatures client-side using HMAC-SHA256 and RSA-PSS keys.
