An automated test showed that my keycloak installation was allowing insecure TLSv1.2 ciphers. I attempted to set the ciphers using the https-cipher-suites property in keycloak.conf, but then when using those ciphers I get a “SSL\_ERROR\_NO\_CYPHER\_OVERLAP”. Is there a specific way I ought to be formatting my ciphers? Are there certain ciphers that keycloak will not use? The documentation on this property are sparse.
