SQLNET.CRYPTO_CHECKSUM_TYPES_CLIENT

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

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

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

speciﬁed, the connection terminates with error message ORA-12650.

Seeding the Random Key Generator (Optional)

Setting this parameter in the sqlnet.ora ﬁle as follows is optional:

SQLNET.CRYPTO_SEED = "10-70 random characters"

The characters that form the value for this parameter can be used to seed the

random number generator that is used to generate cryptographic key material. The

more random the characters entered into this ﬁeld are, the stronger the keys are.

You set this parameter by entering from 10 to 70 random characters into the

preceding statement.
