Lyvoxa implements professional security practices for release integrity verification using SHA256 checksums. This universal standard ensures the software you download is genuine and unmodified, with full compatibility across ArchLinux and all Linux distributions.

• SHA256: Universal cryptographic hash standard
• Cross-Platform: Supported natively on all Linux distributions
• Reliable: Industry-standard algorithm for package integrity
• ArchLinux Compatible: Works seamlessly with pacman

• Consistent Environment: GitHub Actions with locked toolchain
• Source Verification: Build from verified repository commits
• Dependency Locking: Cargo.lock ensures consistent dependencies

# Download the release package and verification files
wget https://github.com/oxyzenQ/lyvoxa/releases/download/stellar-2.0/lyvoxa-stellar-2.0-linux-x86_64.tar.gz
wget https://github.com/oxyzenQ/lyvoxa/releases/download/stellar-2.0/lyvoxa-stellar-2.0-linux-x86_64.tar.gz.sha256

# Verify SHA256 checksum (universal standard)
sha256sum -c lyvoxa-stellar-2.0-linux-x86_64.tar.gz.sha256

# Expected output:
# lyvoxa-stellar-2.0-linux-x86_64.tar.gz: OK

# ArchLinux provides sha256sum natively
sha256sum -c lyvoxa-stellar-2.0-linux-x86_64.tar.gz.sha256

# Alternative
sha256sum -c lyvoxa-stellar-2.0-linux-x86_64.tar.gz.sha256

# After extraction, verify binary properties
tar -xzf lyvoxa-stellar-2.0-linux-x86_64.tar.gz
cd lyvoxa-stellar-2.0-linux-x86_64

# Check binary architecture and linking
file bin/lyvoxa

# Verify version information
./bin/lyvoxa --version

1. Always Verify SHA256: Never skip checksum verification
2. Use Official Sources: Only download from GitHub releases
3. Verify Build Information: Check binary properties after extraction
4. ArchLinux Integration: Leverage native tools compatibility
5. Check Release Notes: Review security information in release notes

1. Reproducible Environment: GitHub Actions with locked Rust toolchain
2. Automated Verification: CI/CD pipeline automatically generates SHA256 checksums
3. Immutable Releases: Once published, releases cannot be modified
4. Audit Trail: All release activities logged in GitHub Actions

1. Stop Installation: Do not proceed with installation
2. Report Issue: Create an issue on GitHub with verification details
3. Re-download: Try downloading from official source again
4. Contact Maintainer: Reach out via GitHub or official channels

• GitHub Issues: For non-sensitive security questions
• Direct Contact: For sensitive security vulnerabilities
• Response Time: Security issues prioritized within 24 hours
