For example, negotiation order is the same regardless of whether tls_version has a value of TLSv1,TLSv1.1,TLSv1.2,TLSv1.3 or TLSv1.3,TLSv1.2,TLSv1.1,TLSv1. TLSv1.2 does not work with all ciphers that have a key size of 512 bits or less. To use this protocol with such a key, set the ssl_cipher system variable on the server side or use the --ssl-cipher client option to specify the cipher name explicitly: AES128-SHAAES128-SHA256AES256-SHAAES256-SHA256CAMELLIA128-SHACAMELLIA256-SHADES-CBC3-SHADHE-RSA-AES256-SHARC4-MD5RC4-SHASEED-SHA For better security, use a certificate with an RSA key size of at least 2048 bits. If the server and client do not have a permitted protocol in common, and a protocol-compatible cipher in common, the server terminates the connection request. Examples: If the server is configured with tls_version=TLSv1.1,TLSv1.2: Connection attempts fail for clients invoked with --tls-version=TLSv1, and for older clients that support only TLSv1. Similarly, connection attempts fail for replicas configured with MASTER_TLS_VERSION = 'TLSv1', and for older replicas that support only TLSv1. If the server is configured with tls_version=TLSv1 or is an older server that supports only TLSv1: Connection attempts fail for clients invoked with --tls-version=TLSv1.1,TLSv1.2. Similarly, connection attempts fail for replicas configured with MASTER_TLS_VERSION = 'TLSv1.1,TLSv1.2'. MySQL permits specifying a list of protocols to support. This list is passed directly down to the underlying SSL library and is ultimately up to that library what protocols it actually enables from the supplied list. Please refer to the MySQL source code and the OpenSSL SSL_CTX_new() documentation for information about how the SSL library handles this.Monitoring Current Client Session TLS Protocol and Cipher To determine which encryption TLS protocol and cipher the current client session uses, check the session values of the Ssl_version and Ssl_cipher status variables: mysql> SELECT * FROM performance_schema.session_status WHERE VARIABLE_NAME IN ('Ssl_version','Ssl_cipher');+---------------+---------------------------+| VARIABLE_NAME | VARIABLE_VALUE |+---------------+---------------------------+| Ssl_cipher | DHE-RSA-AES128-GCM-SHA256 || Ssl_version | TLSv1.2 |+---------------+---------------------------+ If the connection is not

The negotiation process depends on factors such as the SSL library used to compile the server and client, the TLS protocol and encryption cipher configuration, and which key size is used: For a connection attempt to succeed, the server and client TLS protocol configuration must permit some protocol in common. Similarly, the server and client encryption cipher configuration must permit some cipher in common. A given cipher may work only with particular TLS protocols, so a protocol available to the negotiation process is not chosen unless there is also a compatible cipher. If TLSv1.3 is available, it is used if possible. (This means that server and client configuration both must permit TLSv1.3, and both must also permit some TLSv1.3-compatible encryption cipher.) Otherwise, MySQL continues through the list of available protocols, using TLSv1.2 if possible, and so forth. Negotiation proceeds from more secure protocols to less secure. Negotiation order is independent of the order in which protocols.

Than 1024 bits. Add the keyword "rsa2048" to disallow connections with servers having keys smaller than 2048 bits.Note: Prior to Chilkat v9.5.0.55, it was not possible to explicitly list allowed cipher suites. The deprecated means for indicating allowed ciphers was both incomplete and unprecise. For example, the following keywords could be listed to allow matching ciphers: "aes256-cbc", "aes128-cbc", "3des-cbc", and "rc4". These keywords will still be recognized, but programs should be updated to explicitly list the allowed ciphers.secure-renegotiation: Starting in Chilkat v9.5.0.55, the keyword "secure-renegotiation" may be added to require that all renegotions be done securely (as per RFC 5746).best-practices: Starting in Chilkat v9.5.0.55, this property may be set to the single keyword "best-practices". This will allow ciphers based on the current best practices. As new versions of Chilkat are released, the best practices may change. Changes will be noted here. The current best practices are:If the server uses an RSA key, it must be 1024 bits or greater.All renegotations must be secure renegotiations.All ciphers using RC4, DES, or 3DES are disallowed.Example: The following string would restrict to 2 specific cipher suites, require RSA keys to be 1024 bits or greater, and require secure renegotiations: "TLS_DHE_RSA_WITH_AES_256_CBC_SHA256, TLS_RSA_WITH_AES_256_CBC_SHA, rsa1024, secure-renegotiation"topSslProtocolstring SslProtocolSelects the secure protocol to be used for secure (SSL/TLS) connections.
