Nettet21. okt. 2013 · Since RSA is quite slow, the usual way to encrypt large messages is using hybrid encryption. In hybrid encryption you use a fast symmetric encryption algorithm (like AES) for encrypting the data with a random key. The random key is then encrypted with RSA and send along with the symmetric key encrypted data. EDIT: NettetDecrypt the ciphertext to produce the numeric plaintext again. Convert the numeric plaintext back into a string. Judging by your code, you are producing your numeric plaintext (which, for some reason, is called ciphertext) by taking all of the characters in the plaintext string and multiplying them together.
