nameprep造句

• It does not reverse the Nameprep processing, since that is merely a normalization and is by nature irreversible.
• "' Nameprep "'is the process of case-folding to lowercase and removal of some generally invisible code points before it is suitable to represent a domain name, or other such canonical name.
• Nameprep is defined in RFC 3491, " Nameprep : A Stringprep Profile for Internationalized Domain Names ( IDN ) ", as a profile of Stringprep, which is described in RFC 3454, " Preparation of Internationalized Strings ( " stringprep " ) ."
• Nameprep is defined in RFC 3491, " Nameprep : A Stringprep Profile for Internationalized Domain Names ( IDN ) ", as a profile of Stringprep, which is described in RFC 3454, " Preparation of Internationalized Strings ( " stringprep " ) ."
• Note that for DNS use, the domain name string is assumed to have been normalized using Nameprep and ( for top-level domains ) filtered against an officially registered language table before being punycoded, and that the DNS protocol sets limits on the acceptable lengths of the output Punycode string.
• There are good reasons for this, such as the fact that fonts differ in which characters are lookalikes, and the fact that any decision on which character to map to will obviously provide a bias towards users of one script, but it has potentially grave implications for security if not considered by the designers and administrators of systems based on nameprep ( the best known example of this being VeriSign's handling of IDNA names in . com and . net ).
