However, 128 bit encryption should be enough for daily use. To use the 256 bit AES ciphers, it is necessary to install the JCE Unlimited Strength Jurisdiction Policy Files. In 2014, specified in this article SSL Weak Ciphers is obsolete You need use ciphers="TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256,TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA, TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA384,TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA, TLS_ECDHE_RSA_WITH_RC4_128_SHA,TLS_RSA_WITH_AES_128_CBC_SHA256,TLS_RSA_WITH_AES_128_CBC_SHA, TLS_RSA_WITH_AES_256_CBC_SHA256,TLS_RSA_WITH_AES_256_CBC_SHA,SSL_RSA_WITH_RC4_128_SHA" The remaining issue is vulnerability to the "BEAST" attack, which is not possible to mitigate with the Java SSL implementation. We removed those two ciphers, and moved up to a "B" grade. TLS_DHE_RSA_WITH_AES_128_CBC_SHA, SSL_DHE_RSA_WITH_3DES_EDE_CBC_SHA According to the results, the following ciphers are weak, resulting in a "C" grade. We tested these ciphers against SSL Labs' "SSL Server Test" tool (. I recommend deleting quotes and retyping them manually. Notice the difference in the slant on the quotes. Think, this is typo - SSLv3 is working for me.īe careful when using these instructions, since some of the quotation marks in the solution are the wrong characters. In the example i see SSL, but in the first code snippet there is are SSLv3. Using “sslProtocols†by itself resolved my problem. I found it unnecessary to specify “sslProtocol†or “sslEnabledProtocols†with “sslProtocolsâ€Â. If you are trying to disable a specific SSL or TLS version in Tomcat 6 and you are unable to do so using “sslEnabledProtocolsâ€Â, check your version of Tomcat 6. How to Disable Weak Ciphers and SSL 2.0 in Apache.Next, open your server.xml file add the following to your SSL connector: You can do this using an OpenSSL command or by just entering your public domain name at First, verify that you have weak ciphers or SSL 2.0 enabled. If you have a Tomcat server (version 4.1.32 or later), you can disable SSL 2.0 and disable weak ciphers by following these instructions. Tomcat has several weak ciphers enabled by default. You also need to disable weak ciphers or you will fail a PCI compliance scan. In order for merchants to handle credit cards, the Payment Card Industry Data Security Standard (PCI-DSS) requires web sites to “use strong cryptography and security protocols such as SSL/TLS or IPSEC to safeguard sensitive cardholder data during transmission over open, public networks.” That means you must use SSL on your web site if your visitors are transferring their credit card numbers to your server.
