I was wondering if TLS 1.2 is supported by "camel-ftp" library for Java. The version used is 2.17.0.redhat-630262. Or should we upgrade the version to the latest for getting TLS 1.2 support? The Java version is 8.
The SSL support is provided by the underlying JDK. Java 8 has TLS V1.2, so this is available to camel -ftp (sftp endpoint). If you set securityProtocol to TLS, you will get the TLS protocols.
You may want to ensure that only the TLS V1.2 protocols are enabled in your jre/lib/security/java.security file, as the older, weaker, TLS versions are enabled by default.
