I'm encrypting a file using AES-256 in CBC mode. I'm padding to the 16-byte input multiple by using the PKCS#7 limit. The problem I'm currently having is that if I'm transferring or reading the ...
I have a fairly simple Python program using PyCrypto to use AES+CBC to encrypt a stream of input. In order to adhere to the 16-byte input size multiple, I've implemented PKCS#7 by hand. (While I know ...
So for block ciphers you need a fixed size block. If the plaintext length is not a multiple of the block length then you need to pad it. One way you could do this is that for the last block you just ...
Is the initial AES key (expanded to the key schedule) byte padded if less than e.g. 16 bytes? Is there a safe way of determining if decryption was successful (i.e. used the correct key)?
How to remove padded value in Decrypted Message? I am using AES Algorithm.. ex: this is the decrypted message.. "abcdefghijklmn " there is a 2 space in that decrypted message which is equivalent ...
