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

    The Encrypt qualifier encrypts the backup file of the after image
    journal.

    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 see HELP
    ENCRYPT.

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

    This feature only works for a newer format backup file which
    has been created using /FORMAT=NEW_TAPE. Therefore you have
    to specify /FORMAT=NEW_TAPE with this command if you also use
    /ENCRYPT.

    Synonymous with Format=Old_File and Format=New_Tape qualifiers.
    See the description of those qualifiers.
