ssl - 在 Tomcat 5 中启用强密码

Question

我正在尝试改进我的 webapp 允许的密码套件。

在 Tomcat 的 server.xml 中，我定义了以下连接器：

<Connector port="443" maxHttpHeaderSize="8192"
           maxThreads="3000" minSpareThreads="250" maxSpareThreads="500"
           enableLookups="false" disableUploadTimeout="true"
           acceptCount="1000" connectionTimeout="40000"
           scheme="https" secure="true" clientAuth="false" sslProtocol="TLS"
           ciphers="SSL_RSA_WITH_RC4_128_MD5, SSL_RSA_WITH_RC4_128_SHA,
           TLS_RSA_WITH_AES_128_CBC_SHA, TLS_DHE_RSA_WITH_AES_128_CBC_SHA,
           TLS_DHE_DSS_WITH_AES_128_CBC_SHA, SSL_RSA_WITH_3DES_EDE_CBC_SHA,
           SSL_DHE_RSA_WITH_3DES_EDE_CBC_SHA, SSL_DHE_DSS_WITH_3DES_EDE_CBC_SHA,
           ADH-AES256-SHA, AES256-SHA, DHE-DSS-AES256-SHA, DHE-RSA-AES256-SHA"
           keystoreFile="REDACTED" keystorePass="REDACTED" />

服务器启动得很好。一切正常。但是，当我在服务器上运行sslscan时，256 位密码显示为不受支持。

(Abbreviated, sorted output)
Accepted  SSLv3  128 bits  AES128-SHA
Accepted  SSLv3  128 bits  DHE-RSA-AES128-SHA
Accepted  SSLv3  128 bits  RC4-MD5
Accepted  SSLv3  128 bits  RC4-SHA
Accepted  SSLv3  168 bits  DES-CBC3-SHA
Accepted  SSLv3  168 bits  EDH-RSA-DES-CBC3-SHA
Accepted  TLSv1  128 bits  AES128-SHA
Accepted  TLSv1  128 bits  DHE-RSA-AES128-SHA
Accepted  TLSv1  128 bits  RC4-MD5
Accepted  TLSv1  128 bits  RC4-SHA
Accepted  TLSv1  168 bits  DES-CBC3-SHA
Accepted  TLSv1  168 bits  EDH-RSA-DES-CBC3-SHA
Rejected  SSLv3  256 bits  ADH-AES256-SHA
Rejected  SSLv3  256 bits  AES256-SHA
Rejected  SSLv3  256 bits  DHE-DSS-AES256-SHA
Rejected  SSLv3  256 bits  DHE-RSA-AES256-SHA
Rejected  TLSv1  256 bits  ADH-AES256-SHA
Rejected  TLSv1  256 bits  AES256-SHA
Rejected  TLSv1  256 bits  DHE-DSS-AES256-SHA
Rejected  TLSv1  256 bits  DHE-RSA-AES256-SHA

此外，扫描显示首选服务器密码是“SSLv3 128 位 DHE-RSA-AES128-SHA”和“TLSv1 128 位 DHE-RSA-AES128-SHA”。如果 Tomcat 更愿意使用 128 位密码，我很好，但我想为任何严格的客户提供服务。

我忽略了什么？

SSL_DHE_DSS_WITH_3DES_EDE_CBC_SHA
SSL_DHE_DSS_WITH_DES_CBC_SHA
SSL_DHE_RSA_EXPORT_WITH_DES40_CBC_SHA
SSL_DHE_RSA_WITH_3DES_EDE_CBC_SHA
SSL_DHE_RSA_WITH_DES_CBC_SHA
SSL_RSA_EXPORT_WITH_DES40_CBC_SHA
SSL_RSA_EXPORT_WITH_RC4_40_MD5
