Frequently Asked Questions
What is DES/AES encryption and how does it work?
DES (Data Encryption Standard) and AES (Advanced Encryption Standard) are symmetric encryption algorithms. DES uses 64-bit blocks with 56-bit keys, while AES supports 128-bit blocks with 128, 192, or 256-bit keys. AES is the modern standard, replacing DES for enhanced security. Both algorithms use the same key for encryption and decryption, making them suitable for secure data storage and transmission.
Is this encryption tool secure and private?
Yes, all encryption and decryption operations are performed entirely in your browser using client-side JavaScript. Your data never leaves your device, ensuring complete privacy and security. The tool uses well-established cryptographic libraries and follows industry best practices for secure implementation.
What encryption modes are supported?
The tool supports multiple encryption modes including ECB (Electronic Codebook), CBC (Cipher Block Chaining), CTR (Counter), and GCM (Galois Counter Mode). Each mode has different security characteristics: CBC is widely used and secure, GCM provides authenticated encryption, CTR enables parallel processing, and ECB is included for legacy compatibility.
Can I use custom encryption keys?
Yes, you can enter your own encryption keys or use the built-in secure key generator to create random keys of appropriate lengths. The tool validates key lengths based on the selected algorithm and key size. For security, use the key generator to create cryptographically secure random keys.
What output formats are available?
The tool supports multiple output formats including Base64, Hexadecimal, and plain text. Base64 is ideal for text-based systems, Hexadecimal for debugging and low-level operations, and plain text for human-readable results. You can easily switch between formats based on your specific requirements.
Is this tool completely free to use?
Yes, this DES/AES encryption tool is completely free to use with no registration required. There are no usage limits, premium features, or hidden costs. All functionality including key generation, multiple algorithms, modes, and formats are available at no cost.
Can I encrypt files or just text?
This tool is designed for text-based encryption and decryption. You can encrypt any text data including configuration files, JSON, XML, CSV, or other text-based content. For binary files, you would need to first encode them as Base64 text before encryption.
Which algorithm should I choose - DES or AES?
Always choose AES for new implementations. AES-256 is considered military-grade encryption and is virtually uncrackable with current technology. DES is included only for compatibility with legacy systems. DES uses 56-bit keys which are no longer considered secure by modern standards.
