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

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

    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 the Format=New_Tape qualifier. Therefore you
    have to specify the Format=New_Tape qualifier with this command
    if you also use the Encrypt qualifier.

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