for example company B send an encrypted email with company A's public key (RSA/PGP/SSH/openSSL/...) the employer receive the encrypted email and send it to his boss who have the private key to decrypt message. the boss give decrypted email back to employer to work on it. question is can employer compare encrypted email with decrypted version and find out what is private key ? if it is possible then is there anyway to protect cracking private key from decrypted messages and comparing with encrypted messages/public key ?
