Security Features in AESCrypt v3.5

  1. AES-256-GCM Encryption:

    • This version implements AES-256 encryption in Galois/Counter Mode (GCM), providing both confidentiality and integrity. GCM is designed to be efficient and secure, ensuring that encrypted data is protected against unauthorized access while also preventing tampering.

  2. Key Derivation with Argon2id:

    • Utilizes Argon2id for key derivation, which is resistant to both GPU and side-channel attacks. The key derivation function (KDF) parameters are adjustable, allowing for customization of time cost, memory cost, and parallelism to enhance security based on user requirements.

  3. Improved Password Hashing:

    • The implementation now includes strong password hashing using Argon2id, ensuring that user-provided passwords are transformed into secure keys. This adds an extra layer of protection against brute-force attacks.

  4. HMAC for Data Integrity:

    • An HMAC (Hash-based Message Authentication Code) is computed and stored alongside encrypted data. This ensures that any modifications to the encrypted content can be detected during decryption, thus providing a safeguard against data integrity breaches.

  5. Secure Deletion of Original Files:

    • The original files are securely deleted after encryption, ensuring that sensitive data cannot be recovered through standard file recovery methods. The file contents are overwritten with random bytes before deletion.

  6. Salt and IV Generation:

    • A unique salt and initialization vector (IV) are generated for each encryption operation, enhancing security by ensuring that identical plaintexts do not result in identical ciphertexts.

  7. User-Generated Passwords:

    • Users can generate strong, random passwords using a built-in function, which uses a secure method to ensure that passwords are unpredictable and resistant to guessing attacks.

  8. User Interface Enhancements:

    • The graphical user interface (GUI) includes warnings and instructions to guide users through the encryption and decryption processes, ensuring that best practices are followed.

  9. Batch Encryption:

    • The ability to encrypt entire folders at once, allowing users to secure multiple files efficiently while ensuring each file is independently encrypted with robust security measures.

  10. Secure Memory Clearing Feature

  • In order to enhance security, AESCrypt 3.5 Argon implements a feature that ensures sensitive information, such as passwords, is securely cleared from memory after use. This helps prevent unauthorized access to sensitive data that may linger in memory.
