Picocrypt

Picocrypt: Small, Simple, and Secure Encryption In an era where data breaches are common and privacy is increasingly hard to find, the tools we use to protect our information have become more complex. Many encryption suites are bloated, requiring extensive installation processes or deep technical knowledge. Enter , a breath of fresh air in the cybersecurity space that prioritizes simplicity and security without the overhead. What is Picocrypt?

3.2 Implementation Safety

“safe by default, powerful when needed”

This design follows the principle. A 2023 user study (n=42 non‑technical participants) found that 97% successfully encrypted and decrypted a file without assistance, compared to 58% for GPG with Kleopatra and 74% for VeraCrypt. picocrypt

• User can provide two passwords during creation:
  • Cipher: ChaCha20-Poly1305
  • KDF: Argon2id with salt=16B, memory=64 MB, iterations=3, parallelism=1
  • Nonce: 12B random per encryption
  • Tag: 16B (AEAD tag)
  • Password min length: 12 characters (encourage passphrases)
  • Security: PicoCrypt's security relies on the secrecy of the shared key and the complexity of the cryptographic scheme. While it provides reasonable security for casual, low-stakes communication, it should not be used for high-security or sensitive applications.

  You can protect your password with a physical file (a photo, a text file, a binary blob). An attacker needs your password and a specific file to decrypt your data. This provides excellent protection against keyloggers or forced disclosure (you cannot reveal a file you have already deleted from your RAM).
