Default Setting
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.
