Data Encryption and Integrity Parameters

Data Encryption and Integrity Parameters A-7

SQLNET.ENCRYPTION_TYPES_CLIENT

This parameter speciﬁes a list of encryption algorithms used by this client or server

acting as a client. This list is used to negotiate a mutually acceptable algorithm with

the other end of the connection. If an algorithm that is not installed is speciﬁed on

this side, the connection terminates with error message ORA-12650.

SQLNET.CRYPTO_CHECKSUM_TYPES_SERVER

This parameter speciﬁes a list of data integrity algorithms this server or client to

another server uses, in order of intended use. This list is used to negotiate a

mutually acceptable algorithm with the other end of the connection. Each algorithm

is checked against the list of available client algorithm types until a match is found.

If an algorithm is speciﬁed that is not installed on this side, the connection

terminates with error message ORA-12650.

Table A–7 SQLNET.ENCRYPTION_TYPES_CLIENT Parameter Attributes

Attribute Description

Syntax SQLNET.ENCRYPTION_TYPES_CLIENT = (valid_

encryption_algorithm [,valid_encryption_

algorithm])

Valid Values

■ RC4_256: RSA RC4 (256-bit key size).

■ AES256: AES (256-bit key size).

■ AES192: AES (192-bit key size).

■ 3DES168: 3-key Triple-DES (168-bit effective key size).

■ RC4_128: RSA RC4 (128-bit key size).

■ AES128: AES (128-bit key size).

■ 3DES112: 2-key Triple-DES (112-bit effective key size).

■ RC4_56: RSA RC4 (56-bit key size).

■ DES: Standard DES (56-bit key size).

■ RC4_40: RSA RC4 (40-bit key size).

■ DES40: DES40 (40-bit key size).

Default Setting If no algorithms are deﬁned in the local sqlnet.ora ﬁle, all

installed algorithms are used in a negotiation.

Usage Notes You can specify multiple encryption algorithms.
