RSA failed to decrypt.

[Romij Uddin]

Hello ,

I have used following code to generate key.

    CryptoPP::AutoSeededRandomPool rng;

    CryptoPP::InvertibleRSAFunction parameters;

    parameters.GenerateRandomWithKeySize( rng, 1024 );

    CryptoPP::RSA::PrivateKey privateKey( parameters );

    CryptoPP::RSA::PublicKey publicKey( parameters );

 

This code works fine for encryption/deception on single application.

But when i tried to send encrypted message,

from one computer to another computer. Then it failed to decrypt.

And error message is following :

terminate called after throwing an instance of 'CryptoPP::InvalidCiphertext'

  what():  RSA/OAEP-MGF1(SHA-1): invalid ciphertext

fish: “./CryptoPP” terminated by signal SIGABRT (Abort)

How to fix such thing?

You'll probably need to share how you are sending the encrypted message. Maybe you simply need to use a base64 encoder to get crazy characters out of the data you send.
