The ordering of a ciphersuite is very important because it decides which algorithms are going to be selected in priority. Each level shows the list of algorithms returned by its ciphersuite. If you have to pick ciphers manually for your application, make sure you keep the ordering. | The ordering of a ciphersuite is very important because it decides which algorithms are going to be selected in priority.

The ciphersuite numbers listed come from the IANA [https://www.iana.org/assignments/tls-parameters/tls-parameters.xhtml#tls-parameters-4 TLS Cipher Suite Registry]. Previous versions of these recommendations included draft numbers for ECDHE-ECDSA-CHACHA20-POLY1305 (0xCC,0x14) and ECDHE-RSA-CHACHA20-POLY1305 (0xCC,0x13). | |||
