EncryptionTypes (ET)

Purpose

Specifies a comma-separated list of the encryption algorithms to use if Oracle Advanced Security encryption is enabled using the Encryption Level connection property.

Valid Values

encryption_algorithm [[, encryption_algorithm ]...]

where:

encryption_algorithm
is a encryption algorithm specifying an algorithm in the following table:

AES256 | RC4_256 | AES192 | 3DES168 | AES128 | RC4_128 | 3DES112 | RC4_56 | DES | RC4_40

Encryption Algorithm Description
3DES112 Two-key Triple-DES (with an effective key size of 112-bit).
AES128 AES with a 128-bit key size.
AES192 AES with a 192-bit key size.
AES256 AES with a 256-bit key size.
DES DES (with an effective key size of 56-bit).
DES168 Three-key Triple-DES (with an effective key size of 168-bit).
RC4_128 RC4-128 with a 128-bit key size.
RC4_256 RC4 with a 256-bit key size.
RC4_40 RSA RC4 with a 40-bit key size.
RC4_56 RSA RC4 with a 56-bit key size.

Example

Your security environments specifies that you can use RC4 with a 256-bit key size, AES with a 192-bit key size, or two-key Triple-DES with an effective key size of 112-bit. Use the following values: 

EncryptionTypes=RC4_256,AES192,3DES112

Notes

  • This option is ignored if Encryption Level is set to 0 (Rejected).
  • Consult your database administrator concerning the data encryption settings of your Oracle server.
  • This connection option can affect performance.

Default

On the GUI tab: all check boxes are selected.

In the connection string: no encryption methods are specified. The driver sends a list of all of the encryption methods to the Oracle server.
