Hello, I want to decrypt a ciphertext which has been encrypted using the ElGamal-algorithm. I know the parameters a, b which represent the ciphertext, the paramter x (private key), the parameter g (Group Generator) and the modulus p.
I found the functions Decrypt() (from a base class) and the function SymmetricDecrypt() but they both do not take the ciphertext splitted in a and b. Does anybody know how to decrypt the message using crypptopp? The elgamal example in validate2.cpp is not helpful in this case. Thanks in advance, Thorsten
