[MS-DSCPM]§2.2.2.2（校验和）：示例中的BASE16无效 [英] [MS-DSCPM] §2.2.2.2 (Checksum): invalid BASE16 in example

问题描述

我想报告[MS-DSCPM]：期望状态配置拉模型协议中的错误，发布日期为9/15/2017。我实际上并没有使用这个协议，因此我不需要紧急回复。

I'd like to report an error in [MS-DSCPM]: Desired State Configuration Pull Model Protocol, publication date 9/15/2017. I am not actually using this protocol, so I do not require an urgent response.

第2.2.2.2节（校验和）说：

 Checksum = "Checksum" : DQUOTE Check-sumvalue DQUOTE CRLF
 Check-sumvalue = BASE16 ; specified in [RFC4648]
   / 0x00 (Null Character) 
  

示例："Checksum"：" 8eDMbsSDig15Xx + B3msvRrDa5N1njaf5smVujQjhOeI ="

Example: "Checksum":"8eDMbsSDig15Xx+B3msvRrDa5N1njaf5smVujQjhOeI="

" Checksum"：""

"Checksum":""

根据[RFC4648]，BASE16仅使用字符0123456789ABCDEF（不区分大小写）。字符串"8eDMbsSDig15Xx + B3msvRrDa5N1njaf5smVujQjhOeI ="是无效的BASE16，因为它包含"M"和"M"。和其他不允许的角色。不过，
看起来像是有效的BASE64。

According to [RFC4648], BASE16 uses only the characters 0123456789ABCDEF (case insensitive). The string "8eDMbsSDig15Xx+B3msvRrDa5N1njaf5smVujQjhOeI=" is not valid BASE16 because it contains "M" and other disallowed characters. It looks like valid BASE64, though.

ValidateChecksum PowerShell-DSC-for-Linux中的函数在BASE16中格式化校验和，然后比较字符串，所以我认为2.2.2.2节中对BASE16的引用是正确的，并且错误仅在示例中。

The ValidateChecksum function in PowerShell-DSC-for-Linux formats a checksum in BASE16 and then compares strings, so I think the reference to BASE16 in section 2.2.2.2 is correct, and the error is only in the example.

进一步说明，使用"0x00（空字符）"。看起来很可疑。在HTTP标头字段中发送空字符不是常见的做法。我想知道[MS-DSCPM]是否真的通过线路发送空字符，或者它们是否只在内存中存在
。

On a further note, the use of "0x00 (Null Character)" seems suspicious. Sending null characters in HTTP header fields is not a common practice. I wonder whether [MS-DSCPM] really sends the null characters over the wire or whether they exist only in memory.
