PurrCrypt is an innovative approach to steganographic encryption that uses pet-related onomatopoeia as a disguise. Instead of utilizing actual audio recordings, this method cleverly masks encryption processes with the sounds associated with pets, like 'meow' or 'woof'. Users are encouraged to vocalize these sounds during encryption, which enhances the personal connection to the technology, albeit without affecting the performance of the algorithm. Feedback highlights a mix of appreciation and disappointment among users, with some wishing for real sound integration. The application is also noted for being developed in Rust, a programming language favored for its reliability and performance in system-level applications.
