AES vs RSA

Advanced Encryption Standard (AES) and Rivest–Shamir–Adleman (RSA) are both widely used, highly secure encryption algorithms, but they are typically used in different ways:

Symmetric or Asymmetric

• AES is symmetric: AES uses the same key for both encryption and decryption.
• RSA is asymmetric: RSA uses a public key for encryption and a private key for decryption.

Speed

• AES is faster and better suited for encrypting large volumes of data, or for protecting streaming content.
• RSA is slower.

Usage

• RSA is typically used for secure key exchanges and digital signatures.
• Secure communications: RSA is typically used for key exchange in SSL/TLS protocols, ensuring a secure channel for data transmission between clients and servers.
• Digital signatures: RSA's asymmetric properties make it an ideal choice for creating and verifying digital signatures.
• Software protection: RSA is used for software protection.
