Description: The ElGamal algorithm is a more common encryption algorithm, which is based on the 1984 public key cryptosystem and elliptic curve cryptography system. Both digital signature can also be used for data encryption, its security relies on computational finite field discrete logarithm problem. Generated during the encryption process, the length of the ciphertext is plaintext twice, and each encryption will generate a random number K in the ciphertext.
