how do I tell java mail to use the cipher suit I used to use in java 6?<\/strong><\/p>\nEasy, when you’re setting up your Session properties, make sure to include the following key:<\/p>\n
[java]properties.put(“mail.smtp.ssl.ciphersuites”,”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 SSL_RSA_WITH_DES_CBC_SHA SSL_DHE_RSA_WITH_DES_CBC_SHA SSL_DHE_DSS_WITH_DES_CBC_SHA SSL_RSA_EXPORT_WITH_RC4_40_MD5 SSL_RSA_EXPORT_WITH_DES40_CBC_SHA SSL_DHE_RSA_EXPORT_WITH_DES40_CBC_SHA SSL_DHE_DSS_EXPORT_WITH_DES40_CBC_SHA TLS_EMPTY_RENEGOTIATION_INFO_SCSV”);[\/java]<\/p>\n
which specifies in a space separated String a list of tokens that represent the cipher suites the SSL sockets will use. At some point that list gets split into a String[] and passed to SSLSocket.setEnabledCipherSuites.<\/p>\n
This is how my session properties look like in case you want to know:<\/p>\n
[java]
\n Properties properties = new Properties();
\n properties.put(“mail.transport.protocol”, “smtp”);
\n properties.put(“mail.smtp.auth”, true);
\n properties.put(“mail.smtp.ssl.enable”,true);
\n properties.put(“mail.smtp.port”, emailSMTPPort);
\n properties.put(“mail.smtp.host”, emailSMTPHost);
\n properties.put(“mail.smtp.ssl.ciphersuites”,”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 SSL_RSA_WITH_DES_CBC_SHA SSL_DHE_RSA_WITH_DES_CBC_SHA SSL_DHE_DSS_WITH_DES_CBC_SHA SSL_RSA_EXPORT_WITH_RC4_40_MD5 SSL_RSA_EXPORT_WITH_DES40_CBC_SHA SSL_DHE_RSA_EXPORT_WITH_DES40_CBC_SHA SSL_DHE_DSS_EXPORT_WITH_DES40_CBC_SHA TLS_EMPTY_RENEGOTIATION_INFO_SCSV”);
