The encryption cipher suite defines the type of encryption that is used for any data exchanged through an SSL connection. It is negotiated during the SSL handshake.
The following table shows the TLS1 encryption cipher suites used when the OpenAccess ODBC Client negotiates encryption with a server certificate.
| TLS_RSA_WITH_NULL_SHA | TLS_RSA_WITH_AES_256_CBC_SHA |
| TLS_RSA_WITH_AES_128_CBC_SHA | TLS_DHE_DSS_WITH_AES_128_CBC_SHA |
| TLS_DHE_DSS_WITH_AES_256_CBC_SHA | TLS_DHE_RSA_WITH_AES_128_CBC_SHA |
| TLS_DHE_RSA_WITH_AES_256_CBC_SHA |
The following table shows the encryption cipher suites used when the OpenAccess ODBC Client negotiates TLS1 without a server certificate.
| TLS_DH_anon_WITH_AES_128_CBC_SHA | TLS_DH_anon_WITH_AES_256_CBC_SHA |
The following table shows the TLS1.2 encryption cipher suites used when the OpenAccess ODBC Client negotiates encryption with a server certificate.
