Password-lock any file — encryption and unlock data stay inside the file. Open only with your password or PIN.
Pick one file or one folder (same picker pattern as GriGsi Space). Folder contents are packed, then encrypted as one .ggef file.
Upload your .ggef file and enter the same PIN/password. GriGsi hashes your input and compares it to the hash stored inside the file — only then it decrypts.
