Picocrypt is a "finished" piece of software and is in a maintenance-only stage. This does not mean the software is old, outdated, or abandonware, but that the focus is on fixing bugs and ensuring the software continues to work smoothly as opposed to actively developing new features. As well, my time as the developer is limited considering that Picocrypt brings me no monetary benefit and is entirely a gift of my time and skill to the community.

These are high-priority issues and the main purpose of this repository's issue tracker. Make the issue with a short description, and then once the issue is created, add a comment with as many details as possible. Ping me (@HACKERALERT) in the comment so that I can get to it as soon as possible. Keep in mind that I define "bug" as something wrong with Picocrypt's code itself. If it's not Picocrypt's fault, it's not a bug.

Usually these issues are not directly caused by Picocrypt's code. Create the issue and in a separate comment, provide details about the environment you're running in (like OS, DE, etc.). **Do not ping me initially.** Let the issue sit for at least *3 days* to allow other users to potentially help you resolve the issue.

Usually these issues are not directly caused by Picocrypt's code. If you're on Windows, see [here](https://github.com/Picocrypt/Picocrypt/issues/91). If you're on Linux, install some packages and try again (see [here](https://github.com/Picocrypt/Picocrypt/tree/main/src#1-prerequisites)). Picocrypt only targets Windows 11, Ubuntu 24/Debian 12, and macOS 15 or later, so *do not create an issue if your OS is older than those; that is your problem, not mine*. If none of the points above help, create the issue and in a separate comment, provide details about the environment you're running in (like OS, DE, etc.). **Do not ping me initially.** Let the issue sit for at least *5 days* to allow other users to potentially help you resolve the issue.

Picocrypt is mature software; I do not intend to add any new features. Generally, do not create any feature requests unless it's very minor and can be implemented with low effort and minimal impact on reliability and security. What is considered "minor" is subjective, but here is an example: "the ability to decrypt a volume entirely in-memory" is pretty significant, while "auto start encryption on pressing the Enter key" is relatively minor. A proof-of-concept link to code or a fork would be appreciated.

Picocrypt prioritizes correctness and reliability over performance, so many parts of the code are written sequentially and don't use concurrency. This is intentional and need not be pointed out. Unless performance is absolutely atrocious to the point where it is indicative of a potential bug, do not make issues about performance.

# Future
<ul>
<li>Migrate golang.org/x/crypto to standard library imports (https://github.com/golang/go/issues/65269)</li>
<li>Figure out how to remove use of temporary files completely</li>
</ul>
# v1.48 (Released 04/15/2025)
<ul>
<li>✓ Allow pressing 'Enter' key to press Start/Process button</li>
<li>✓ Update "Encrypt" button to "Zip and Encrypt" if multiple files</li>
<li>✓ Give user estimated required free disk space in status label</li>
<li>✓ Encrypt previously unencrypted temporary zip files</li>
<li>✓ Add `.incomplete` to filenames while work is in progress</li>
<li>✓ Use `encrypted-*.zip.pcv` output name instead of `Encrypted.zip.pcv`</li>
<li>✓ Use 0700 permissions when auto unzipping and creating folders</li>
</ul>

## Windows
Picocrypt for Windows is as simple as it gets. To download the latest, standalone, and portable executable for Windows, click <a href="https://github.com/Picocrypt/Picocrypt/releases/latest/download/Picocrypt.exe">here</a>. If Microsoft Defender or your antivirus flags Picocrypt as a virus, please do your part and submit it as a false positive for the betterment of everyone.
If you use Picocrypt frequently, you can download an installer <a href="https://github.com/Picocrypt/Picocrypt/releases/download/1.47/Install-Picocrypt.exe">here</a> for easier launching. It does not require any admin permissions to install and it also bundles a software OpenGL renderer for compatibility, so if the portable executable isn't working, this installer likely will.
## macOS
Picocrypt for macOS is very simple as well. Download Picocrypt <a href="https://github.com/Picocrypt/Picocrypt/releases/latest/download/Picocrypt.dmg">here</a>, open the container, and drag Picocrypt to your Applications. You may need to manually trust the app from a terminal and control-click on the app if macOS prevents you from opening it:
