implement in java RSA cryptosystem with a 1024-bit key strength (this means that p will be 512 bits and q will be 512 bits). You need to do 3 separate programs. One of them will be a key generation algorithm, the second will be the encryption, and the third will be the decryption.
The key generation program will be responsible for generating both the public and private key and will write it on separate files. The syntax that Im looking for is as follows:
Keygen
Public key: N,e Private key: N,d,p,q Where N is p*q, p and q are the secret primes, e is the public exponent and d is the private exponent. Please note that you are RESPONSIBLE for making sure that your program generates p and q that are ALWAYS primes.
The Encryption program is responsible for encrypting any plaintext decimal message that the user provides as an argument given a public key and outputs the ciphertext to the user to stdout/or whatever the compiler you are using. The syntax for the encryption would be as follows: Encrypt
The Decryption program is responsible for decrypting any ciphertext decimal message that the user provides as an argument given a private key and outputs the plaintext to the user to stdout/or whatever the compiler you are using. The syntax for the decryption would be as follows: Decrypt
