This encryption method is called symmetric encryption, also known as single key encryption. The encryption algorithms based on “symmetric key” mainly include DES, 3DES (tripledes), AES, RC2, RC4, RC5 and blowfish.

The following image, provided by wikipedia, summarises the CTR mode of operation: To use AES in CTR mode we implement a couple of additional functions. First we need a function that combines the nonce with the counter and encrypts them with the main key, to generate a block. Step 4: From Encryption Method dropdown list, select one value (AES CBC, AES ECB, AES CFB, AES CTR, AES OFB, DES, TripleDES, Rabbit, RC4, RC4Drop). Step 5: In Step 4, if you select one of AES methods like AES CBC or AES ECB or AES CFB or AES CTR or AES OFB, then you get to see Padding dropdown list.

We have chosen AES in CTR mode as the cryptographic cipher of our choice, transmitting the initialization vector and the message number in clear such that both know which to use (next). Since encryption is not enough (and integrity actually much better), we are also pondering which authentication algorithm to use.

The following are 30 code examples for showing how to use Crypto.Cipher.AES.MODE_CTR().These examples are extracted from open source projects. You can vote up the ones you like or vote down the ones you don't like, and go to the original project or source file by following the links above each example.

For more details on the AES standard, refer to the AES standard document. 3.1 AES Encryption The AES-128 encryption process involves 10 rounds of encryption along with an initial round for the 128 bit data encryption. AES comes in 128-bit, 192-bit, and 256-bit implementations, with AES 256 being the most secure. In this article, we’ll explain how AES 256 encryption works and how it can be used to protect your data. What Is AES 256-Bit Encryption? AES was developed in response to the needs of the U.S. government.
