Configuration Parameters

Oracle Advanced Security FIPS 140-1 Settings D-3

The speciﬁed algorithm must be installed or the connection terminates. For FIPS

140-1 compliance, only DES encryption is permitted and therefore the following

parameter setting is mandatory:

SQLNET.ENCRYPTION_TYPES_SERVER=(DES|DES40)

Client Encryption Selection List

The ENCRYPTION_TYPES_CLIENT parameter speciﬁes the list of encryption algorithms

which the client is prepared to use for the connection with the server. In order for a

connection to be successful, the algorithm must ﬁrst be installed and the encryption

type must be mutually acceptable to the server.

To create a connection with a server that is conﬁgured for FIPS 140-1, the following

parameter setting is mandatory:

SQLNET.ENCRYPTION_TYPES_CLIENT=(DES|DES40)

Cryptographic Seed Value

The CRYPTO_SEED parameter contains characters which are part of the seed for the

random number generator. There are no explicit requirements for the value of this

parameter within the FIPS 140-1 standard, however it is suggested that a large set of

random characters, up to 70, is chosen as follows:

SQLNET.CRYPTO_SEED=10_to_70_random_characters

FIPS Parameter

The default setting of the FIPS_140 parameter is FALSE. Setting the parameter to

TRUE is mandatory for both client and server to ensure Oracle Advanced Security

complies with the standards deﬁned in FIPS 140-1 as follows:

SQLNET.FIPS_140=TRUE

Note: Use a text editor to set the FIPS_140 parameter in the

sqlnet.ora ﬁle. You cannot use Oracle Net Manager to set this

parameter.
