is a lightweight, open-source file encryption tool designed for high security and extreme simplicity
Decryption is just as easy: drag the .pcv file into the window, enter the password, and click . File associations allow you to double-click a .pcv file to open it directly in decrypt mode on Windows and macOS.
Picocrypt combats this by using , the winner of the Password Hashing Competition. Argon2id is a memory-hard function, meaning it deliberately requires a significant amount of computer memory and processing power to calculate a password hash. This makes it financially and technologically impractical for attackers to use specialized hardware (like GPUs or ASICs) to crack your password. 3. Reputed Components and No External Dependencies
The audit specifically called out concerns with the original approach of using a SHA3-512 hash of the Argon2id master key for integrity checking. Picocrypt-NG 2.0 addressed this by replacing the SHA3-512 hash with , a more robust construction for verifying header integrity. picocrypt
It does not protect against:
: The combination of Deniability, portable execution, and high-tier encryption provides physical and digital safety nets for high-risk users. ⚠️ Current Status & Considerations
: It is a portable application, meaning you can run it directly from a USB drive on Windows, macOS, or Linux without leaving traces on the host system. is a lightweight, open-source file encryption tool designed
: This feature strips identifying file "headers" from the encrypted volume. If intercepted, the file appears as a stream of random or corrupted bytes, making it impossible for a bad actor to prove it is an encrypted archive without the password. Reed-Solomon Error Correction
Magnetic degradation and bit rot frequently destroy older backup archives stored on physical media. Picocrypt mitigates this by integrating directly into the encrypted volume container. This addition allows the software to fully recover and accurately reconstruct data even if up to 3% of the underlying file volume encounters physical corruption or bad sectors. Additional Capabilities
Picocrypt is a small, cross-platform, open-source file encryption tool designed to provide maximum security with a minimalist user experience. Created by Evan Su (HACKERALERT), it aims to make high-grade encryption accessible to non-technical users who might find tools like VeraCrypt too complex. Argon2id is a memory-hard function, meaning it deliberately
Do you need assistance generating a or setting up a keyfile ?
Picocrypt (and its NG fork) represents a rare breed of software: tools that are simultaneously simple enough for beginners and secure enough for security professionals. Whether you're creating encrypted backups of your hard drives, protecting sensitive documents before uploading to cloud storage, or establishing a secure long-term archive of important data, Picocrypt delivers without complexity.
PicoCrypt is an example of paper-based cryptography, which has been used throughout history to protect communication. Other examples include:
