-
NONE
-
specifies that no encryption is used.
-
RC2
-
specifies to use the RC2 encryption algorithm
that was developed by RSA Security. The RC2 algorithm uses a block cipher
to encrypt 64-bit blocks. The RC2 key size is variable and can range from
8 to 256 bits. A single message can be expanded to 8 bytes. RC2 encryption
is an alternative to Data Encryption Standard (DES) encryption.
-
RC4
-
specifies to use the RC4 encryption algorithm
that was developed by RSA Security. The RC4 algorithm uses a stream cipher
to encrypt 1 byte at a time. The RC4 key size is variable and can range from
8 to 2,048 bits.
-
DES
-
specifies to use the Data Encryption Standard
(DES) encryption algorithm that was developed by IBM. The DES algorithm uses
a block cipher to encrypt 64-bit blocks. DES uses a 56-bit key.
-
TRIPLEDES
-
specifies to use the TRIPLEDES encryption
algorithm, which processes the DES encryption algorithm sequentially three
times on the data. TRIPLEDES uses a different 56-bit key for each iteration
of the encryption. A single message can be expanded to 8 bytes.
-
SASPROPRIETARY
-
specifies to use basic encryption services
in all operating environments. The SASPROPRIETARY algorithm uses a 32-bit
key and can expand a single message by one-third. No additional product license
is required. This is the default.
Note: In a configuration file or at SAS
invocation, the syntax for SAS system options is specific to your operating
environment. For more information, see the SAS documentation for your operating
environment. ![[cautionend]](../../../../common/63294/HTML/default/images/cautend.gif)
The SAS IOM supports encrypted communication
with the metadata server. Use the METAENCRYPTALG and METAENCRYPTLEVEL system
options to define the type and level of encryption that SAS clients use when
they communicate with the metadata server.
If you specify an encryption algorithm other than SASPROPRIETARY
(alias SAS), you must have a product license for SAS/SECURE software. For
more information, see the
SAS Intelligence Platform: Security Administration Guide.
