CompTIA A+ 220-1102 Practice Question

AES (Advanced Encryption Standard) - This is correct. AES is the widely adopted standard for securing data in transit and at rest. It is known for its robustness, efficiency, and ability to handle large amounts of data securely. AES uses symmetric encryption and offers key lengths of 128, 192, or 256 bits, providing high levels of security. It is commonly used in modern cryptographic applications, including HTTPS, VPNs, and encrypted file storage.

Blowfish - Blowfish is a symmetric encryption algorithm that is secure and fast, but it is less widely adopted compared to AES. It is used in specific applications but has largely been replaced by AES in modern systems.

RSA - RSA is an asymmetric encryption algorithm used for secure key exchange, digital signatures, and encrypting small amounts of data. It is often combined with AES for hybrid encryption systems but is not typically used for encrypting large volumes of data due to its slower performance.

3DES (Triple Data Encryption Standard) - 3DES is a symmetric encryption algorithm that applies the DES algorithm three times to each data block. While secure, it is less efficient and slower compared to AES and has been largely deprecated in favor of AES.
