The PWENCODE procedure enables you to encode passwords. Encoding obfuscates the data. Unlike encryption, encoding is a reversible permutation of the data and uses no keys.

Encoded passwords can be used in place of plaintext passwords in SAS programs that access relational database management systems (RDBMSs) and various servers. Examples are SAS/CONNECT servers, SAS/SHARE servers, SAS Integrated Object Model (IOM) servers, SAS Metadata Servers, and more.
