... vault is encrypted and decrypted automatically from there. No second password to remember per file or folder. What it does: Fully offline no cloud, no server, no account required Three encryption layers by default (AES-256-GCM, ChaCha20, rotor cipher), a fourth can be enabled with one click Argon2id key derivation to harden against brute-force attacks RCX files send a file so only one specific, pre-confirmed contact can open it, verified once through a secret word, never needed ...

... runs from the Spartan Scytale (650 BC) all the way to modern cryptography, with four new entries: Diffie-Hellman (1976), RSA (1977), AES (2001) and ChaCha20 (2008). It finally tells the public-key story, not just the classical ciphers. MORE IN THE TOOL New cipher
