# PostQuantumApps – Trial Release (1-Year)
## Overview
This repository contains **trial versions (1-year validity)** of **PostQuantumApps**, a collection of **command-line cryptography utilities** designed to protect sensitive data against **post-quantum decryption threats**.
The tools focus on **practical, real-world usage**, offering simple CLI workflows that encapsulate complex cryptographic operations, including **post-quantum resistant key exchange, encryption, and secure file handling**.
These applications are intended for **technical users**, such as developers, researchers, security professionals, and advanced users.
---
## Included Tools (CLI)
Depending on the platform, this repository may include:
- **PQCypher** – Post-quantum secure file encryption/decryption
- **PQFileCompressAndLock** – Compression + encryption in a single step
- **PQEmbeddFileInto** – Secure steganographic embedding of files
- Additional utilities and bundles
Each tool is delivered as a **standalone command-line executable**.
---
## Trial License
- ⏳ **Trial duration:** 1 year from first execution
- 🔒 **Fully functional**, with trial limitations
- 💼 Intended for **evaluation, testing, and non-production use**

## Platform Support
- **Windows** (x64)
- **Linux** (Debian-based distributions)
- **macOS**
Each platform has its own directory and bundled binaries.
---
## Antivirus & False Positives (Important)
⚠️ **False positives may occur.**
Because these applications:
- perform cryptographic operations,
- manipulate files at a low level,
- use strong encryption techniques,
some antivirus or endpoint protection systems **may incorrectly flag them as malware**.
These are **false positives**.
No telemetry, spyware, backdoors, or network activity is included.
If needed, add the binaries to your antivirus exclusion list.
---
## Usage Responsibility
These tools are **powerful cryptographic utilities**.
By using them, you acknowledge that:
- you understand the implications of encryption,
- you are responsible for how and where the tools are used,
- encrypted data may become **irrecoverable** if keys are lost or misused.
---
## Limitation of Liability
**THE SOFTWARE IS PROVIDED “AS IS”, WITHOUT WARRANTY OF ANY KIND.**
To the maximum extent permitted by law:
- The authors and contributors **shall not be held liable** for any direct or indirect damage, data loss, financial loss, or system failure.
- This includes, but is not limited to, damages resulting from:
- incorrect use of the applications,
- misuse, misconfiguration, or user error,
- loss of encryption keys,
- incompatibilities with third-party software or systems.
You assume **full responsibility** for any outcome resulting from the use of these tools.
---
## No Recovery Guarantee
⚠️ **There is no guarantee of data recovery.**
If encrypted data is lost due to:
- forgotten passwords,
- deleted keys,
- corrupted files,
recovery may be **cryptographically impossible**.
Always test with non-critical data first.
