This is the size of the input data, the message Text for encryption.. Note that after AES-CTR encryption the initial vector (IV) should be stored along with the ciphertext, because without it, the decryption will be impossible. 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.

RFC 5930 AES-CTR for IKEv2 July 2010 3.IKEv2 Conventions The use of AES-CTR for the IKE SA is negotiated in the same way as AES-CTR for ESP. The Transform ID (ENCR_AES_CTR) is the same; the key length transform attribute is used in the same way; and the keying material (consisting of the actual key and the nonce) is derived in the same way. 2019-09-13 The AES Symmetric-Key Cipher - Concepts.

AES-CTR uses the AES block cipher to create a stream cipher. Data is encrypted and decrypted by XORing with the key stream produced by AES encrypting sequential counter block values. AES-CTR is easy to implement, and AES-CTR can be pipelined and parallelized.

A specification for the encryption of electronic data established by the U.S. National Institute of Standards and Technology (NIST) in 2001. You can do what you are proposing if the AES-GCM IV size is of 96 bits.
