![]() ![]() These keys will not be used for encryption of any kind. The problem is that I am able to decrypt the cipher using a a completely different key from the enryption. These keys will only be used for is authentication, including signing messages and signing during session key exchange. To decrypt the message I simply first decrypt the IV and then decrypt the cipher with the decrypted IV and the key.Ĭurrently I am using EBC to encrypt the IV, as otherwhise I would need another IV to encrypt the previous IV and so on. I know that it is not required to encrypt the IV, but I need it for my usecase. An IV is used to avert repetitions in data encryption, which makes it difficult for hackers, who use dictionary attacks, to find a way to break a cipher. Then I need to encrypt the IV with the same key. By returning out of the most inner using you can remove byte decrypted. ![]() Decrypt () The default Mode of RijndaelManaged is already CipherMode.CBC so there is no need to set it again. At the command-line, you can use the -P option (uppercase P) to print the salt, key and IV, and then exit. #Encrypto decrypt key iv passwordBut, if I decrypt with the same IV as used in encryption, I see my original plain text message. The salt is a piece of random bytes generated when encrypting, stored in the file header upon decryption, the salt is retrieved from the header, and the key and IV are re-computed from the provided password and salt. As the method is public you should validate its parameter. Now, I tried decryption with a random IV (different from the one used for encryption), and got gibberish text, instead of the original plain text message which I expected. You can use om (key) instead new Buffer (key) For variable contenting a number you can change : new Buffer (num) to Buffer. You can use the parameterless CreateEncryptor () method because you already set the Key and IV. I need to encrypt plaintext using CTR with a random IV. Read the file, encrypt the content, write encrypted content to the file. ![]()
