Encrypt=({Value=|Name=}[,Algorithm=])

    The Encrypt qualifier decrypts the file of an after-image journal
    backup.

    Specify a key value as a string or the name of a predefined key.
    If no algorithm name is specified the default is DESCBC. For
    details on the Value, Name and Algorithm parameters type HELP
    ENCRYPT at the OpenVMS prompt.

    This feature requires the OpenVMS Encrypt product to be installed
    and licensed on your system.

    This feature only works for a newer format backup file which
    has been created using the Format=New_Tape qualifier. You must
    specify the Format=New_Tape qualifier with this command if you
    use the Encrypt qualifier.
