PCA Files

Petoron Crypto Archiver (PCA) v1.0

This is the first public release of PCA - a minimal, zero-trace archiver designed to encrypt any file or folder into a fully sealed .pca binary archive.

Built upon the cryptographic foundation of PTBC (Petoron Time Burn Cipher), PCA focuses on permanent protection, no time decay, and total irreversibility.

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)

Philosophy:

• If you lose the password - it’s over
• If the file is modified - decryption fails
• If leaked - no one can read without the key
  PCA doesn’t compress, doesn’t forgive, and never forgets :))
