What is an ssl error weak server ephemeral dh key, and how do I repair it?
1. Select Ignore SSL Error in Firefox
Although this may not be the safest option, the majority of the people in the community have claimed that this way works.
To make this work, you’ll need to set two security codes in Mozilla Firefox to false.
- Click the Firefox icon after opening the Mozilla Firefox browser.
- Type about:config into the search bar.
- A warning box will appear in the browser, stating that this may void your warranty. Ignore that and click on I promise I’ll be careful!
- You will be taken to a new page where you must write security.ssl3.dhe rsa aes 128 sha.
- If the Value tab is set to True, change it to False.
- After that, type security.ssl3.dhe rsa aes 256 sha into the search bar.
- Change the value from true to false once again.
2. In Tomcat Server, disable SSL 2.0
The Tomcat server may be turned on by default, especially if SSL 2.0 is used.
In this instance, enter your domain in this SSL Server Test to see if you have weak ciphers or SSL 2.0 enabled.
Then, open the server.xml file and add the following to your SSL connector to deactivate weak ciphers:
SSLEnabled=”true” sslEnabledProtocols=”TLSv1,TLSv1.1,TLSv1.2″ 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”
