I want a java program to encrypt or decrypt a plaintext message/ ciphertext using RSA. Encryption: Users can enter the public key e & n value and the plaintext message. The program will output the result in hexadecimal digits. Decryption: Users can enter the Private key d & n value and the ciphertext hexadecimal digits. The program will output the result back into plaintext. Example: You want to Encrypt (e) or Decrypt (d)? e Please enter the Public key value e? 5 Please enter the Public key value n? 119 Please enter the Plaintext message? You should work hard. Encrypting.... Ciphertext in Hex: DEA32B21EB931AAFC8E You want to Encrypt (e) or Decrypt (d)? d Please enter the Private key value d? 77 Please enter the Private key value n? 119 Please enter the ciphertext in Hex? DE133BCBC335D113AF Decrypting.... Plaintext: in cryptography. The program can not use other external libraries like KeyPairGenerator.
