No install, no dependencies, completely open source (MIT License), and only 2,000 lines of code. The Cryptography Behind the Curtain Picocrypt does not invent new cryptography (a cardinal sin). Instead, it selects the absolute best primitives and glues them together perfectly.
Because Picocrypt uses the Go standard library for crypto, it does not rely on OpenSSL, Libsodium, or any external DLLs. This eliminates an entire class of supply-chain attacks where hackers compromise a dependency library. picocrypt
