Frequently Asked Questions

General Questions

Q: Is my data safe when using this tool? A: Yes, all encryption and decryption operations are performed entirely within your browser. No data is transmitted to external servers or stored anywhere.
Q: Which encryption algorithm should I choose? A: For most users, AES is recommended due to its excellent security and performance. Choose TripleDES for legacy compatibility, Rabbit for high-speed applications, or RC4 for lightweight needs.
Q: Can I use this tool for commercial purposes? A: Yes, this tool is free for both personal and commercial use. However, ensure compliance with your organization's security policies and regulatory requirements.

Technical Questions

Q: What key sizes are supported? A: The tool supports variable key sizes depending on the algorithm. AES supports 128, 192, and 256-bit keys, while other algorithms have their own specifications.
Q: Is the tool compatible with other encryption software? A: Yes, the tool uses standard encryption algorithms that are compatible with other implementations. However, ensure identical parameters (key, IV, padding) for successful decryption.
Q: How do I handle large files? A: While optimized for performance, very large files may require chunked processing. Consider breaking large datasets into smaller segments for optimal performance.

Security Questions

Q: How secure are the encryption algorithms? A: All supported algorithms are industry-standard and widely used. AES is approved by the NSA for classified information, while others have extensive cryptographic analysis and real-world usage.
Q: What happens if I forget my encryption key? A: Encryption keys cannot be recovered. If you lose your key, the encrypted data cannot be decrypted. Always maintain secure backups of your encryption keys.
Q: Can the tool be used offline? A: Once loaded, the tool can function offline as all processing is client-side. However, initial loading requires an internet connection.

Integration Examples

JavaScript Integration

// Example of integrating encryption functionality
