1, RSA algorithm: RSA algorithm is one of the earliest widely used asymmetric encryption algorithms. It uses the difficulty of prime number decomposition to realize encryption and decryption by generating public key and private key.

2.DSA algorithm: DSA algorithm is a digital signature algorithm, which is based on discrete logarithm problem and used for digital signature and verification.

3.ECC algorithm: ECC algorithm (elliptic curve cipher) is an encryption algorithm based on elliptic curve.

4.ElGamal algorithm: ElGamal algorithm is an encryption algorithm based on discrete logarithm problem, which is widely used in digital signature and encrypted communication.

These algorithms are representative of asymmetric encryption algorithms, and they have their own advantages and disadvantages in different scenarios. We should choose the appropriate algorithm to encrypt and decrypt the data according to the actual needs.
