cyansalt/font-cloak

font-cloak is a Node.js package that encrypts text data by shuffling font character mappings and generating a new font file with characters placed in Private Use Areas. It's designed for developers who need to obfuscate text content (like screen dimensions or sensitive data) on websites by converting it into unreadable characters that can only be displayed using the generated font. The package includes runtime functions to encode text using the generated magic string, making it useful for web applications that want to hide certain information from casual inspection while maintaining visual display through custom fonts.
