Before, all of information was put on a paper, in recording, and or other device whereas now we only need the computer to produce unlimited information on a digital data. Data security is not the main attention today. The digital data that people can access easily are proportional with Cyber Crime increase such as Piracy, data manipulation, and speculation happening today. Cryptography Technic is one of the best choice to improve data security. Cryptography is data manipulation technic so peoples can only see the data in the form of unknown codes. RSA algorithm is one of the asymmetric key algorithm, so the key used in ecnryption is different with key used for Decryption. Realibility parameters of this cryptography algorithm is the prime values used so the large the keys is more difficult to solve. Key Generation process is also part of algorithm used. This research uses Monte Carlo Algorithm for Random Numbers Generation, and Miller Rabin Algorithm as Primality Test Algorithm of the numbers. Combining these algorithms in Keys Generation surely improve the Large Prime Number Generation Success rate thus improving data security. The algorithm is applied to files with different formats and sizes. The result of encryption from this application maybe restored to its original form by using the decryption process with successful recovery percentage of 100 percent.} }
