Note about Password Security:

  • The password is not included in the output for security reasons
  • Keep your password safe and separate from the encrypted data
  • You'll need the same password to decrypt this data later
  • If you lose the password, the data cannot be recovered

About Encryption Name:

  • The encryption name is optional and only used for identification
  • It does not affect the encryption or decryption process
  • If no name is provided, it will be saved as "Unnamed Encryption"
  • You can use it to organize and identify different encrypted files

About AES Encryption

Understanding AES

AES (Advanced Encryption Standard) stands as the gold standard for symmetric encryption algorithms. Adopted by the U.S. government and trusted worldwide, AES delivers exceptional security combined with outstanding performance for protecting sensitive information.

Core Specifications:

  • Algorithm Type: Symmetric encryption
  • Key Options: 128, 192, or 256 bits
  • Block Processing: 128 bits per block
  • Structure: Substitution-permutation network

Symmetric Encryption Explained

AES employs symmetric encryption, meaning identical keys handle both encryption and decryption operations. This approach necessitates secure key sharing between communicating parties while delivering superior performance.

Symmetric Encryption Advantages:

  • Lightning-fast processing speeds
  • Optimized for bulk data encryption
  • Straightforward implementation
  • Minimal resource consumption

Security Excellence

🛡️ Military-Grade Protection:

AES offers uncompromised security that meets the highest standards for protecting classified and sensitive information worldwide.

  • Resistant to all known cryptographic attacks
  • Approved for TOP SECRET government data
  • Continuously tested by security experts globally
  • Future-proof against quantum computing threats (AES-256)

Choose AES for mission-critical applications where data security cannot be compromised. It remains the preferred choice for modern encryption needs.

Operating Modes Overview

  • CBC (Cipher Block Chaining): Links blocks sequentially using previous ciphertext for enhanced security
  • CFB (Cipher Feedback): Transforms block encryption into stream processing
  • CTR (Counter Mode): Employs incremental counter values for parallel processing
  • OFB (Output Feedback): Generates keystream independent of plaintext
  • GCM (Galois/Counter Mode): Combines encryption with built-in authentication

Advanced Capabilities

  • Comprehensive mode selection for specialized requirements
  • Flexible padding schemes for various data formats
  • Robust key derivation via PBKDF2 or EvpKDF algorithms
