Which algorithm provides asymmetric encryption?

RC4 (Rivest Cipher 4) is a symmetric stream cipher, which uses the same key for both encryption and decryption.

RSA (Rivest-Shamir-Adleman) is an asymmetric encryption algorithm, meaning it employs a pair of different keys-a public key for encryption and a private key for decryption. This property makes it suitable for secure key exchange and digital signatures.

AES (Advanced Encryption Standard) is a symmetric block cipher, meaning it utilizes a single, shared key for both encryption and decryption.

3DES (Triple Data Encryption Standard) is a symmetric block cipher that applies the DES algorithm three times, also using shared keys for encryption and decryption.
