PTBC
irreversible encryption with time self-destruction
...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.
