AES is a symmetric key encryption cipher, and it is generally regarded as the "gold standard” for encrypting data. AES is NIST-certified and is used by the US government for protecting "secure” data, which has led to a more general adoption of AES as the standard symmetric key cipher of choice by just about everyone.

This version supports 128 bits key encryption only. This is AES, also known by its original name Rijndael, was selected by the NIST in 2000 to find a successor for the dated Data Encryption Standard(DES). AES is a block cipher, that means encryption happens on fixed-length groups of bits. In our case the algorithm defines 128 bit blocks.
AES-CTR Encryption/Decryption. 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.
However, strictly speaking, AES-GCM uses AES-CTR under the hood. If you must use AES-CTR, the same rules apply as for AES-CBC: encKey 2018-01-26 · 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.
Developers can misuse cryptography when they don't fully understand the options. Let's look at how this applies to AES (Advanced Encryption Standard).

Counter mode uses the forward transformation for both encryption and decryption.
RFC 5297 SIV-AES October 2008 1.3.4.Robustness versus Performance SIV cannot perform at the same high throughput rates that other authenticated encryption schemes can (e.g., [] or []) due to the requirement for two passes of the data, but for situations where performance is not a limiting factor -- e.g., control plane applications -- it can provide a robust alternative, especially when
AES¶ AES (Advanced Encryption Standard) is a symmetric block cipher standardized by NIST.
