我正在研究SSL 3.0和TLS 1.0的BEAST攻击。 要了解SSL 3.0支持的密码套件集，我输入以下命令：

在输出中，一些ciper规范名称包括操作模式（例如，DES-CBC-SHA的CBC），但其他的则不包括（例如AES128-SHA）。
我的问题是，当在SSL / TLS握手中选择AES128-SHA1时，每种基于块的密码套件使用什么操作模式？它是否默认为CBC模式？
答案 0 :(得分：2)
从OpenSSL documentation，您可以获得正式名称。
AES128-SHA - ＆gt; TLS_RSA_WITH_AES_128_CBC_SHA
然后，使用tables in Appendix C of the TLS specification，获取您想要的详细信息。
