PicoCrypt does not compromise on security. It intentionally chooses modern cryptographic primitives over older, legacy standards. 1. XChaCha20-Poly1305
You're referring to PicoCrypt, a simple, paper-based cryptographic scheme.
Picocrypt is a free, open-source file encryption software designed to provide users with a straightforward and efficient way to protect their files from unauthorized access. Developed with a focus on simplicity and security, Picocrypt allows users to encrypt files using strong encryption algorithms, ensuring that only authorized individuals can access the encrypted data.

This article explores what makes PicoCrypt a standout choice for securing your files, how it works, and why it might be the ideal encryption solution for your needs. What is PicoCrypt?
Picocrypt deliberately avoids older cryptographic primitives like AES-CBC in favor of modern, high-speed, and structurally sound algorithms.
The name "pico" implies its defining characteristic—smallness. Unlike traditional encryption utilities that require complex installation processes, background system services, and hundreds of megabytes of disk space, Picocrypt is a single executable file that measures just a few megabytes. It requires no installation, leaves no footprints in your system registry, and can be run directly from a USB thumb drive on Windows, macOS, or Linux. PicoCrypt does not compromise on security

The PicoCrypt scheme consists of:
: The developer has stated that the core cryptography is finished and does not require frequent updates.
Picocrypt uses the cipher for encryption, which is widely considered a modern and highly secure alternative to AES-256. Alongside this, it employs Argon2id for key derivation, the winner of the Password Hashing Competition, which makes it exceptionally resistant to brute-force and side-channel attacks. For users with extreme security requirements, a "paranoid mode" is available that cascades XChaCha20 with Serpent encryption, providing an additional layer of defense in depth.
