I do not see this listed on Gpedit/admin templates/network/ssl Config setting/SSL Cipher suite order. Additionally, its important to consult your servers documentation for specifics on which protocols and algorithms it supports. Its somewhat like SSL Labs tools, only for home use. You might want to double check that. You'll have to examine the docs for the servers your interested in. IIS Crypto is a free tool that gives administrators the ability to enable or disable protocols, ciphers, hashes and key exchange algorithms on Windows Server 2008, 2012, 2016, 2019 and 2022. I can see in the handshake packet a bunch of suites being offered ("TLSCipherSuites: TLS_DHE_RSA_WITH_CAMELLIA_256_CBC_SHA { 0x00, 0x88 } etc", but I can't tell which one is being picked. Click here to choose your version and download. To find out which combinations of elliptic curves and cipher suites will be enabled in FIPS mode, see section 3.3.1 of Guidelines for the Selection, Configuration, and Use of TLS Implementations. Check Cipher Suites from Application server with openssl command SSL vs TLS Summary An SSL cipher, or an SSL cipher suite, is a set of algorithms or a set of instructions/steps that helps to establish a secure connection between two entities.
