is a lightweight, open-source file encryption tool designed for high security and extreme simplicity. It serves as a portable alternative to more complex software like VeraCrypt or less secure options like standard 7-Zip archives. Core Features & Security
If you just want to encrypt a tax document or a private photo before uploading it to Google Drive or Dropbox, Picocrypt is perfect. picocrypt
You have family photos spanning 20 years. Hard drives rot. Picocrypt is the only consumer tool that actively protects against bit rot. You encrypt your photo archive once, store it on two drives, and sleep soundly knowing that a flipped bit in 2035 won't destroy your child's first birthday photo. is a lightweight, open-source file encryption tool designed
The Edward Snowden disclosures of 2013 triggered a widespread re‑evaluation of consumer encryption tools. In response, many projects pivoted toward stronger defaults, post‑quantum preparedness, and increased transparency. However, a parallel trend emerged: feature bloat. Tools like GnuPG (GPG) offer dozens of algorithms, compatibility modes, and configuration flags—each a potential foot‑gun for non‑expert users. You have family photos spanning 20 years
Picocrypt offers a "Paranoid" mode. This feature appends a "keyfile" (a separate file acting as a second factor) to the derivation process. This effectively allows for Two-Factor Authentication (2FA) for files: an attacker would need both the password and the specific keyfile to decrypt the data. This mitigates the risk of password theft alone.
In the event that a mathematician discovers a devastating flaw in the math of AES and Serpent simultaneously (an astronomically unlikely event), Picocrypt also applies ChaCha20. This is the stream cipher trusted by Google for TLS (HTTPS) and Cloudflare.
