<p class="MsoNormal">PWG 5100.11 (JPS2) defines the “job-password-encryption-supported” attribute. One of the keywords defined in JPS2 is ’sha’. Neither the keyword nor the description is clear as to which SHA generation is being used. Is this SHA-0 or SHA-1?
Do we need to define additional keywords to bring this up-to-date?<u></u><u></u></p>
