Crypto Protocol Version

Attribute

CryptoProtocolVersion (CPV)

Purpose

Specifies a comma-separated list of the cryptographic protocols to use when SSL is enabled using the Encryption Method connection option (EncryptionMethod=1 | 6). When multiple protocols are specified, the driver uses the highest version supported by the server. If none of the specified protocols are supported by the database server, behavior is determined by the setting of the EncryptionMethod connection option.

Valid Values

cryptographic_protocol [[, cryptographic_protocol ]...]
where:
cryptographic_protocol
is one of the following cryptographic protocols:
TLSv1.2 | TLSv1.1 | TLSv1 | SSLv3 | SSLv2
Caution: Good security practices recommend using TLSv1 or higher, due to known vulnerabilities in the SSLv2 and SSLv3 protocols.

Example

Your security environments specifies that you can use TLSv1 and SSLv3. Use the following values:
CryptoProtocolVersion=TLSv1,SSLv3

Notes

*This option is ignored if Encryption Method is set to 0 - No Encryption.
*Consult your database administrator concerning the data encryption settings of your server.

Default

TLSv1.2, TLSv1.1,TLSv1, SSLv3
