There are a variety of reasons why AES is more widely used: AES is a standard. AES has been vetted by cryptanalysts more extensively than Camellia. As a result, we can have greater confidence in the security of AES than in Camellia. Therefore, on the merits, there may be good reasons to choose AES over Camellia. AES is a government standard (FIPS). ...

As a bonus feature, AES has hardware support in Intel processors which implement the AES instruction set, with AMD support coming soon in their Bulldozer based processors. The AES instructions set consists of six instructions. Four instructions, namely AESENC, AESENCLAST, AESDEC, AESDECLAST, are provided for data encryption and decryption (the ...

The reason why you see that is because Camellia is the highest-preference cipher in NSS (Chrome and Firefox). Servers that support Camellia and use the client-preferred cipher suite will use Camellia. NSS's rationale for this ordering is: National ciphers such as Camellia are listed before international ciphers such as AES and RC4 to allow servers ...

Camellia is a symmetric block cipher; the same key is used for both encryption and decryption. And, as a block cipher, it can be used in any of the standard modes (CBC, CTR, CFB, GCM, even ECB, although use of ECB for any block cipher is not encouraged).

This depends on your intended use. If the hardware environment supports processor instructions for AES, that would be the preferred choice, as it will have higher performance and less side channel leakage. If you do not have these instructions, then from a technical standpoint each should have equivalent levels of security with a given bit size. Ciphersuite ...

From a technical side, there are three general scenarios that should be handled differently: Scenario 1: You control the configuration of the server your client software will connect to, and expect to retain that control for the life time of your client software. In such case, you only have to (and probably should) enable a single cipher suite, both client ...
