It is free. It is auditable. It fixes bitrot. It uses gold-standard algorithms. And it fits on a floppy disk (metaphorically).

A: No. Because the code is open source, any backdoor would be visible. The algorithms (Argon2, XChaCha20) are public domain standards accepted by the global crypto community.

A: Roughly 500 bytes for headers (negligible), plus parity overhead (if enabled). A 1GB file with 5% parity becomes a 1.05GB .pcv file. It is free

This deep-dive article will explore what Picocrypt is, how it demolishes the competition, why it uses the "right" cryptography, and how you can integrate it into your daily digital hygiene routine. Picocrypt is a free, open-source, cross-platform file encryption utility designed to provide "simple, secure, and safe" encryption. Written primarily in Go, it is a single, standalone executable (roughly 3-4 MB) that requires no installation, no dependencies, and no administrative privileges. It uses gold-standard algorithms

When a piece of software contains hundreds of thousands of lines of code, it inevitably contains bugs, backdoors, or unintended vulnerabilities.
