Encryption Parameters

For CA ACF2, the encryption processing information used to determine eligible data sets is stored in the $USERDATA field component of the key set, which is 64 bytes long.

CA Tape Encryption selects files for encryption based on a character string that is recognizable in the $USERDATA field within the CA@BES resource definition.

The DATA field must include a CA Tape Encryption parameter, in the form of BES=(string_value) or BESn=(string_value). Do not include this parameter within apostrophes or other delimiters.

You can include additional text before or after the BES= or BESn= parameter. A comma or blank must immediately precede the BES= or BESn= statement if either is not the leftmost text in the description field.

The description field can contain up to 64 alphanumeric and special characters. If you enter lowercase characters, they are converted to uppercase.

The security selection data set feature does not support the use of commas and command delimiters or imbedded blanks.
