Difference Between AES, DES, and RSA

AES, DES, and RSA are cryptographic algorithms used for secure data encryption, but they function differently.

Comparison Table

Feature AES (Advanced Encryption Standard) DES (Data Encryption Standard) RSA (Rivest-Shamir-Adleman)
Type Symmetric Symmetric Asymmetric
Key Size 128, 192, or 256 bits 56 bits 1024, 2048, or 4096 bits
Security Strong (widely used) Weak (easily broken) Strong (used for secure communications)
Performance Fast and efficient Slow and outdated Slower due to key size
Use Cases Secure communication, file encryption, financial transactions Legacy systems, older encryption protocols Digital signatures, secure key exchange

Overview of Algorithms

AES: A modern, secure encryption standard used in various applications including banking and government security.

DES: An older encryption standard that is now considered weak due to its small key size.

RSA: A widely used asymmetric encryption algorithm, particularly for secure key exchanges and digital signatures.
