Abstract

n securing data can be done by way of encryption or commonly called Cryptography. The purpose of using Cryptography itself is to make the data sent difficult to read by third parties who are not responsible for stealing data. In cryptographic text, a key generator is used as an automatic generating process, namely the Linear Congruential Generator in the encryption process to make it easier to process by the Elgamal and Knapsack algorithms using a combination of cryptographic algorithms, where messages will be encoded using the ElGamal algorithm, then the results (ciphertext) will be encrypted. again using the Knapsack algorithm, ElGamal Algorithm and Knapsack meet the data integrity requirements. The results of the message decryption test will be the same as the initial plaintext (the original message). And the results of the ciphertext decryption test will be the same as the key that has been used for the text encryption process.
