Picocrypt Instant

Here’s a deep feature concept for Picocrypt — a lightweight, secure encryption tool — that goes beyond standard file encryption and adds advanced utility for power users and security professionals.

Picocrypt solves all three: No install, no dependencies, completely open source (MIT License), and only 2,000 lines of code. picocrypt

5.3 Nonce Handling

XChaCha20’s 192‑bit nonce is generated via crypto_rand() (OS‑level CSPRNG). Even encrypting billions of files under the same key, the probability of nonce collision is astronomically low. Picocrypt does not implement stateful nonce tracking—a deliberate simplification given the nonce space. Here’s a deep feature concept for Picocrypt —

Decrypting: Double click the .pcv file. Enter password. Click "Decrypt." Done. completely open source (MIT License)
