This is software that can protect and restore files in its own unique format. You can both protect and restore with just this one tool.
It was created as a harassment-themed toy project. However, the contents are quite serious. It creates a .spy file by simply adding a bit of information to the original file.
Features (quoted from GitHub README)
Multi-stage encryption: A robust process combining classical Vigenère cipher (byte-level XOR) and modern AES-256-GCM.
Full-width shared key: Access key generation using 16 full-width characters. Intentionally reduces convenience to create tension during input.
Self-destruct function: If the specified expiration date is exceeded by even 1 second, or if the key is entered incorrectly 3 times, the file is overwritten 3 times with random data and physically destroyed.
Evidence destruction: Upon successful restoration, the original encrypted file (.spy) is automatically physically destroyed, leaving no trace.
