One or more JSSE cipher suite names and/or regular expressions can be specified. Separate cipher suite names or expressions using commas, semicolons or spaces. JSSE cipher suite names can be found at https://docs.oracle.com/javase/8/docs/technotes/guides/security/StandardNames.html#ciphersuites.

The list of cipher suites to be used. For example, to use the cipher suites TLS_RSA_WITH_AES_128_CBC_SHA256 and TLS_RSA_WITH_AES_128_CBC_SHA, set the property as follows.

java.property.com.tibco.security.ssl.includeCiphers=TLS_RSA_WITH_AES_128_CBC_SHA256,TLS_RSA_WITH_AES_128_CBC_SHA

com.tibco.security.ssl.excludeCiphers

The list of cipher suites to be excluded. For example, to exclude the cipher suites TLS_RSA_WITH_AES_128_CBC_SHA256 and TLS_RSA_WITH_AES_128_CBC_SHA, set the property as follows.

java.property.com.tibco.security.ssl.excludeCiphers=TLS_RSA_WITH_AES_128_CBC_SHA256,TLS_RSA_WITH_AES_128_CBC_SHA
