This article provides information and recommendation for the Cipher error after applying a RC4 third-party SSL certificate.
This issue is related to a JAVA vulnerability with RC4 Cipher suite. RC4 Cipher Suite is considered a weak Cipher algorithim by industry standards and was removed in JAVA version 1.8.0_60 and above. See article below:
If you generated a certificate using RC4 Cipher algorithm, this will cause the Cipher error when accessing VMAN via SSL (port 8443). See sample error below:
cmmq0015 uses an unsupported protocol.
VMAN 6.3.1 JAVA version does not support RC4 Cipher suite as per the JAVA.
Generate a certificate that VMAN Cipher suite supports. See the following list of Cipher suites supported:
Note: A simple RSA_SHA (SHA256withRSA) is supported and commonly used.
