WebJul 11, 2024 · If you have an RSA public key ( e, N) (in the case of RSA2048 N will be 2048 bits) and private key d then you can only encrypt messages m whose integer representation is less than N. Recall that in RSA encryption is defined as c = m e mod N where c is the resulting ciphertext, and decryption is defined as m = c d mod N. WebCryptography is the study of secure communications techniques that allow only the sender and intended recipient of a message to view its contents. The term is derived from the Greek word kryptos, which means hidden.

WebApr 10, 2024 · A encrypts the plain text message using B’s public key. When the encrypted message reaches B, B uses his private key to decrypt the message and read it. Consider another person C, who got hold of the encrypted message sent by A to B. C cannot do anything with it unless he has B’s private key.
