Picocrypt -

Picocrypt supports , allowing you to require both a password and a separate file (such as an image or document) to decrypt your data. This provides two-factor-like security: even if your password is compromised, the attacker would still need the keyfile.

It runs seamlessly across major operating systems including Windows, macOS, and Linux. The Architecture of Security

As of this writing, Picocrypt has been reviewed by independent security researchers (including notable figures on GitHub and the Go cryptography subreddit). The author, Evan Su, deliberately keeps the dependencies to an absolute minimum (primarily Go's standard library and golang.org/x/crypto ).

Optionally uses the Deflate algorithm to reduce file size before encryption. picocrypt

The Cryptographic Backbone: How Picocrypt Protects Your Data

Originally created by developer Evan Su, Picocrypt was built with a singular philosophy: . This minimalist approach ensures that the tool does exactly what it promises—securely encrypt your data—without unnecessary features that could introduce vulnerabilities. Picocrypt supports , allowing you to require both

Picocrypt is a free, open-source, and lightweight file encryption utility. It is designed to secure files and folders quickly without requiring complex installation processes.

Picocrypt is a lightweight, open-source encryption software designed to provide secure data protection for individuals and organizations. Developed by Jean-Philippe OCaS, Picocrypt aims to offer a simple, user-friendly, and highly secure encryption solution for files and folders.

Standard block-based encryption algorithms like AES often rely on hardware acceleration to remain performant. Picocrypt utilizes , a highly efficient stream cipher that runs quickly in software without requiring specialized CPU instruction sets. XChaCha20 employs an extended 192-bit nonce, practically eliminating the risk of nonce reuse, which can compromise security in standard ChaCha20 setups.

To encrypt data into a single protected "piece" (a .pcv file):

Picocrypt is not just another encryption tool; it is a course correction in the industry. It prioritizes mathematical rigor over features. It prioritizes portability over profit.

Picocrypt does not encrypt folders natively. Instead, it does something better. You drag a folder onto the executable, and it automatically creates an unencrypted TAR archive in memory, encrypts that archive, and outputs a .pcv file. To decrypt, it reverses the process. You get folder support without the complexity of FUSE drivers (which Cryptomator requires).
