Decrypt rsa 1024 python pycrypto8/24/2023 ![]() ![]() ![]() The encryptor object has an internal state when used in the CBC mode, so if you try to encrypt the same text with the same encryptor once again - you will get different results. Again, since the API is low-level, the encrypt method expects your input to consist of an integral number of 16-byte blocks (16 is the size of the basic AES block). We create a new AES encryptor object with, and give it the encryption key and the mode. I won't get into all the details, but unless you have some special requirements, CBC should be good enough for you. The next thing the code does is set the block mode of AES. What's useful about this technique is that you don't have to worry about manually padding your password - SHA-256 will scramble a 32-byte block out of any password for you. So be wary of brute-force password guessing, and pick a relatively strong password ( kitty probably won't do). Keep in mind that this 32-byte key only has as much entropy as your original password.
