The PWENCODE Procedure

PROC PWENCODE Statement

PROC PWENCODE IN='password' <OUT=fileref> <METHOD=encoding-method>;

IN='password'

specifies the password to encode. The password can contain up to a maximum of 512 characters, which include alphanumeric characters, spaces, and special characters. If the password contains embedded single or double quotation marks, use the standard SAS rules for quoting character constants (see "SAS Constants in Expressions" in SAS Language Reference: Concepts for details).

Options

OUT=fileref

specifies a fileref to which the output string is to be written. If the OUT= option is not specified, the output string is written to the SAS log.

METHOD=encoding-method

specifies the encoding method. Here are the supported values for encoding-method:

Supported Encoding Methods
Encoding Method	Description	Supported Data Encryption Algorithm
sas001	Uses base64 to encode passwords.	None
sas002, which can also be specified as sasenc	Uses a 32-bit key to encode passwords. This is the default.	SASProprietary, which is included in SAS software.
sas003	Uses a 256-bit key to encode passwords.	AES (Advanced Encryption Standard), which is supported in SAS/SECURE*.

* SAS/SECURE is an add-on product that requires a separate license. For details about SAS/SECURE, the SASProprietary algorithm, and the AES algorithm, see Encryption in SAS.

If the METHOD= option is omitted, the default encoding method, sas002, is used automatically.
