# Security
Security is Picocrypt's sole focus. I was in need of a secure, reliable, and future-proof encryption tool that didn't require bloatware and containers, but I couldn't find one, so I created Picocrypt. Picocrypt uses XChaCha20-Poly1305, which is a revision of the eSTREAM winner, Salsa20. XChaCha20-Poly1305 has been through a significant amount of cryptanalysis and was selected by security engineers at Google to be used in modern TLS suites. It's considered to be the future of encryption, and makes Picocrypt more secure than Bitlocker, NordLocker, and 7-Zip. It's used by Cloudflare, Google, and many other forward-thinking companies.
For key derivation, Picocrypt uses Argon2ID, winner of the PHC (Password Hashing Competition), which was completed in 2015. Argon2ID is even slower than Scrypt and Bcrypt (for those that don't understand crypto, this is a good thing), making GPU, ASIC, and FPGA attacks impracticle due to the huge amount of RAM that is used and written to during the key derivation.

Both XChaCha20-Poly1305 and Argon2ID are well recognized within the cryptography community and both are mature and future-proof. Let me get this clear: <i>I did not write the crypto for Picocrypt</i>. Instead, I followed cryptography's number one rule: <i>Don't roll your own crypto</i>. Picocrypt uses two Python libraries, <code>argon2-cffi</code> and <code>pycryptodome</code>, both of which are well known and popular within the Python community. For people who want to know how Picocrypt handles the crypto, or for the paranoid, here is a breakdown of how Picocrypt protects your data:
