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.

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.
