SSL RC4 Cipher Suites Checker
Check if your server supports RC4 cipher suites. Disable RC4 cipher suites and use modern encryption methods like AES or ChaCha20 with TLS 1.2 or TLS 1.3.

What is SSL RC4 Cipher Suites?
The RC4 cipher suite is a type of encryption used in SSL/TLS communications that has known vulnerabilities, particularly related to weaknesses in the way it handles randomness during the encryption process. Due to its susceptibility to attacks such as the BEAST (Browser Exploit Against SSL/TLS) attack, the use of RC4 cipher suites is generally discouraged in modern secure communications.
Attackers can exploit weaknesses in RC4 to decrypt data and manipulate connections. The use of RC4 cipher suites is linked to increased risks of man-in-the-middle attacks, where attackers can intercept and alter data without detection. Due to these risks, organizations are recommended to disable RC4 cipher suites and migrate to more secure cipher suites, such as AES or ChaCha20.
To ensure strong encryption in your SSL/TLS configuration, it is essential to disable support for RC4 cipher suites and enable cipher suites that use modern encryption methods like AES or ChaCha20 with TLS 1.2 or TLS 1.3. This will help mitigate the risks associated with RC4 cipher suites.
