A version of Plum Cave that employs the "ChaCha20 + Twofish-256 CBC + HMAC-SHA3-512" authenticated encryption scheme for data encryption and ML-KEM-1024 for quantum-resistant key exchange.

Petoron Crypto Archiver (PCA) Key features: AES-256-CFB encryption with unique IV per archive Argon2id key derivation (256MB RAM / time_cost=3 / parallelism=4) HMAC-SHA512 integrity and anti-tampering check No compression, no fingerprinting, no trace of original data Works with both single files and entire directories Fully CLI-based, portable, and open format (.pca) https://github.com/01alekseev/PCA

...Key features: AES-CFB encryption with per-file IV Argon2id key derivation with 256MB RAM resistance TTL (time to live) built directly into the encrypted file HMAC-SHA512 integrity verification Self-deleting mode (--autowipe) and one-time access marking (--onetime) No file metadata, no recovery, no password resets Philosophy: If you lose the password - it’s over. If time expires - it’s gone. PTBC doesn’t forgive, doesn’t forget, and doesn’t leak. https://github.com/01alekseev/PTBC

Petoron Quantum Standard (PQS) v1.2 A fully custom, offline encryption standard - built entirely from scratch. PQS v1.2 is a minimalistic, self-contained encryption engine for secure file protection, with zero reliance on external cryptographic libraries. PBKDF2-HMAC-SHA256 (200k iterations, adjustable) for password hardening. Key separation via BLAKE2s - independent keys for encryption and MAC. BLAKE2s-MAC authentication - 16-byte tag, any modification = instant rejection. Streaming keystream generator - secure, large-scale XOR without key reuse. Fake padding (HEAD/TAIL) - obfuscates binary boundaries and payload structure. ...
