Aes 256 bits gcm
In this video you will learn how to use the shared key generated using #ECDH to encrypt and decrypt messages using the symmetric key #AES256 algorithm with a As we covered, you can actually safely run AES in GCM or CCM with 128-bit keys and be fine. You’re getting equivalent of 3072-bit RSA in terms of the security level. But we typically suggest going with 256-bit keys so that you maintain maximum computational hardness for the longest period of time. GCM requires an IV, it is used both by AES-CTR and by AES-GMAC, so no matter what you are doing with GCM, you need to pass an IV. It is required to be unique not necessarily random. Usually, implementations take a 96-bit IV and this is the recommended way to use GCM according to NIST. (UDP), we use AES-256 GCM mode to encrypt these compressed data streams.

If all of your systems support AES-256-GCM, and have the resources to run it, and have a higher security need, then use AES-256-GCM. For example, I have systems that do not support anything newer than SSL3, RC4 and MD5, with 1024-bit certs.

This Recommendation specifies an algorithm called Galois/Counter Mode (GCM) for authenticated encryption with associated data. GCM is constructed from an approved symmetric key block cipher with a block size of 128 bits, such as the Advanced Encryption Standard (AES This new attack, by Alex Biryukov, Orr Dunkelman, Nathan Keller, Dmitry Khovratovich, and Adi Shamir, is against AES-256 that uses only two related keys and 2 39 time to recover the complete 256-bit key of a 9-round version, or 2 45 time for a 10-round version with a stronger type of related subkey attack, or 2 70 time for an 11-round version. 256-bit AES uses 14 rounds, so these attacks are not effective against full AES. To prevent nonce reuse in a client-server protocol, either use different keys for each direction, or make sure that a bit is masked in one direction, and set in the other. The crypto_kx_*() API can be used to do so.

GCM provides authentication, removing the need for an HMAC SHA hashing function. It is also slightly faster than CBC because it uses hardware acceleration (by threading to multiple processor cores). AES-128 provides more than enough security margin for the foreseeable future. But if you're already using AES-256, there's no reason to change.” About.
