دربارهٔ این افزونه
A comprehensive browser sidebar designed for developers, security professionals, and anyone needing reliable cryptographic functions. Unlike online hash generators that send your data to external servers, HashGen processes everything safely locally in your browser using Firefox's built-in Web Crypto API.
🔒 Security-First Design
Privacy Protection:
• Zero data collection: We don't track you or your data.
• No network dependencies: Works completely offline.
• Local processing only: Your sensitive data never leaves your browser.
Secure Implementation:
• Uses standardized Web Crypto API instead of risky custom implementations.
• Excludes vulnerable algorithms (MD5 not included due to collision attacks).
• Follows Mozilla security best practices.
• No dangerous APIs.
⚡ Core Features
Cryptographic Hashing:
• SHA-256 (current industry standard).
• SHA-384 & SHA-512 (high-security variants).
• SHA-1 (legacy compatibility with appropriate warnings).
Encoding Support:
• Base64 encoding and decoding.
• Proper Unicode handling.
• Error validation for invalid inputs.
Productivity Tools:
• Sidebar interface: Always accessible while browsing.
• Text Selection: Grab highlighted text from any webpage.
• Auto-copy: Automatically copy results to clipboard.
• Auto-encode: Hash text as you type.
• Keyboard shortcut (Ctrl+Shift+H) for quick access.
• Context menu integration for selected text.
🎯 Professional Use Cases
For Developers:
• Quick hash generation during development.
• Testing cryptographic functions.
• Data format validation.
For Security Professionals:
• File integrity verification.
• Password hash generation (for testing).
• Security protocol development.
For IT Administrators:
• Checksum verification.
• Configuration file processing.
• System documentation.
🔧 Technical Excellence
Algorithm Selection:
Algorithms carefully selected based on security and practicality. SHA-256 serves as the default for most use cases, with SHA-384/512 available for higher security requirements. MD5 was explicitly excluded due to well-documented cryptographic weaknesses.
Performance:
• Leverages native browser cryptography for maximum speed.
• Efficient memory usage.
• Responsive interface with instant results.
Compatibility:
• Works with Firefox 109.0+.
• No external dependencies.
• Clean, intuitive interface.
📋 Permissions Justification
• HashGen requests minimal permissions essential for functionality.
• No unnecessary permissions are requested, and the extension explicitly declares no data collection in the manifest.
🌟 Why Choose HashGen
• Trustworthy: Open source, transparent functionality.
• Private: Your data never leaves your computer.
• Reliable: Uses browser's built-in cryptographic functions.
• Convenient: Always available in your sidebar.
• Secure: Follows industry best practices.
HashGen embodies the principle that security tools should be both powerful and privacy-respecting. Whether you're a developer testing hash functions or a security professional verifying data integrity, HashGen provides the tools you need while protecting your privacy.
