Next the AES cipher object is created. Counter (CTR) mode is used. Just a few words on why I chose CTR mode. It basically turns a block cipher into a stream cipher and therefore needs no padding. This nicely avoids padding based ciphertext attacks and takes away one thing that the end programmer could screw up.

This document describes the use of AES Counter Mode (AES-CTR), with an explicit initialization vector (IV), as an IPsec Encapsulating Security Payload (ESP) [ ESP] confidentiality mechanism. This document does not provide an overview of IPsec. AES-CTR (counter) mode is another popular symmetric encryption algorithm. It is advantageous because of a few features: 1. The data size does not have to be multiple of 16 bytes. 2.

It basically turns a block cipher into a stream cipher and therefore needs no padding. This nicely avoids padding based ciphertext attacks and takes away one thing that the end programmer could screw up. ' Create a new instance of the Aes ' class. This generates a new key and initialization ' vector (IV). Using myAes As Aes = Aes.Create() ' Encrypt the string to an array of bytes. Dim encrypted As Byte() = EncryptStringToBytes_Aes(original, myAes.Key, myAes.IV) ' Decrypt the bytes to a string.

Please use AES-GCM instead, which looks a lot like AES-CTR anyway. This is in fact mentioned right on the documentation of Crypto++. The IV of CTR mode is

For increased security, the preferred crypto algorithm for the SSH session is the Advanced Encryption Standard counter mode (AES-CTR). SSH version 2 (SSHv2) supports AES-CTR encryption for 128-, 192-, and 256-bit key length. From the supported AES-CTR algorithms, the preferred algorithm is chosen based on the processing capability.

(C) AES CTR Mode Encryption. Demonstrates how to encrypt using AES CTR mode. CTR mode is special in a few ways: (1) Padding doesn't apply. Normally, a block encryption algorithm (AES, Blowfish, DES, RC2, etc.) emit encrypted output that is a multiple of the block size (16 bytes for AES as an example).

CTR mode has similar characteristics to OFB, but also allows a random access property during decryption. CTR mode is well suited to operate on a multi-processor machine where blocks can be encrypted in parallel. Furthermore, it does not suffer from the short-cycle problem that can affect OFB. AES-CTR ciphers implementation. Cipher functionality is accessed using traits from re-exported cipher crate. This crate will select appropriate implementation at Can decrypt any data block, or decrypt blocks out of order due to AES-CTR usage.
