SAS System Options for Encryption |
Specifies the key length that is used by the encryption algorithm
for encrypted client/server data transfers.

NETENCRYPTKEYLEN= 0 | 40 | 128

-
0
-
specifies that the maximum key length that
is supported at both the client and the server is used.
-
40
-
specifies a key length of 40 bits for the
RC2 and RC4 algorithms.
-
128
-
specifies a key length of 128 bits for the
RC2 and RC4 algorithms. If either the client or the server does not support
128-bit encryption, the client cannot connect to the server.
The
NETENCRYPTKEYLEN= option supports only the RC2 and RC4 algorithms. The SASProprietary,
DES, TripleDES, SSL, and AES algorithms are not supported.
By default, if you try to connect a computer that is capable of only
a 40-bit key length to a computer that is capable of both a 40-bit and a 128-bit
key length, the connection is made using the lesser key length. If both computers
are capable of 128-bit key lengths, a 128-bit key length is used.
Using longer keys consumes more CPU cycles. If you do
not need a high level of encryption, set NETENCRYPTKEYLEN=40 to decrease CPU
usage.
