Re: Using AES-256/SHA instead of 3DES/MD5 AES is a newer and more secure encryption algorithm than 3DES. Of course not all devices currently support AES whereas 3DES is fairly common.
secure tls_rsa_with_aes_256_cbc_sha256 ; secure tls_rsa_with_aes_256_cbc_sha Mar 31, 2009 · All were coded in C++, compiled with Microsoft Visual C++ 2005 SP1 (whole program optimization, optimize for speed), and ran on an Intel Core 2 1.83 GHz processor under Windows Vista in 32-bit mode. x86/MMX/SSE2 assembly language routines were used for integer arithmetic, AES, VMAC, Sosemanuk, Panama, Salsa20, SHA-256, SHA-512, Tiger, and TLS Cipher Suites in Windows 10 v1809. 10/09/2018; 3 minutes to read; In this article. Cipher suites can only be negotiated for TLS versions which support them. In last year general plan Announcing SSL Labs Grading Changes for 2017 there is a statement if server uses only Forward Secrecy ciphers the grade will go down to B. This hasn't happened yet, but currently implemented ssllabs test there is a warning that servers only supporting non-forward secrecy ciphers grade will be reduced to B from March 2018. P.S. I am aware of AES-GCM/CCM, but this scheme would work with the basic AES, SHA and HMAC algorithms that are found in most crypto packages. This solution might also be slower, but that too is out of the scope for the question. RFC 4492 describes elliptic curve cipher suites for Transport Layer Security (TLS). However, all those cipher suites use SHA-1 as their MAC algorithm. This document describes sixteen new CipherSuites for TLS/DTLS which specify stronger digest algorithms. Eight use HMAC with SHA-256 or SHA-384 and eight use AES in Galois Counter Mode (GCM). Sha-256 is a function of algorithm Sha-2 (as 384, 512, and more recently 224 bits versions), which is the evolution of Sha-1, itself an evolution of Sha-0.Sha-2 algorithm was developed by NSA to answer the security problem of Sha-1, since the theorical discover of a 2^63 operations for collisions.

SHA-256 (256 bit) is part of SHA-2 set of cryptographic hash functions, designed by the U.S. National Security Agency (NSA) and published in 2001 by the NIST as a U.S. Federal Information Processing Standard (FIPS). A hash function is an algorithm that transforms (hashes) an arbitrary set of data elements, such as a text file, into a single
