我正在寫一個批處理文件，我需要它來驗證文件的MD5散列，然後繼續處理腳本。例如：在批處理中驗證MD5哈希值？
@echo off
if MD5 equ 79054025255fb1a26e4bc422aef54eb4 (
echo MD5 identical!
) else (
echo MD5 does not match.
)
謝謝！

標準的Windows工具CERTUTIL可用於生成MD5（及其他）散列。
例如：
certutil -hashfile yourFile MD5
然而，輸出（之前的版本的Windows 10）將不會被格式化爲連續的十六進制數字單個字符串。
npocmaka在他的批處理實用程序中使用了CERTUTIL來生成單個MD5字符串。
以類似的方式，我也用CERTUTIL我的工具：HASHSUM.BAT - Unix工具一樣的md5sum，shasum一個批處理文件，仿真等
HASHSUM.BAT確實比計算MD5單個文件多，但它也很方便使用你想要的東西。
例如：
echo 79054025255fb1a26e4bc422aef54eb4 yourFileName | hashsum /c /ns
REM - There must be exactly two spaces between the MD5 hash and the filename
會產生輸出像
---------- <stdin> ----------
OK: yourFileName
或
---------- <stdin> ----------
*FAILED: yourFileName
或者你可以把輸出的總量控制
echo 79054025255fb1a26e4bc422aef54eb4 yourFileName | hashsum /c /q && (
echo MD5 identical!
) || (
echo MD5 does not match.
)
或者，如果你真的想要的，你可以自己捕捉的MD5值，並做比較：
for /f %%N in ('hashsum /a md5 yourFileName') do set "MD5=%%N"
if %MD5% equ 79054025255fb1a26e4bc422aef54eb4 (
echo MD5 identical!
) else (
echo MD5 does not match.
)
我張貼的代碼爲當前版本HASHSUM.BAT的1.4，但我不承諾保持此代碼最新。我建議你從DOSTIPS site where I originally posted it獲得代碼。在那裏你可以看到所有HASHSUM.BAT功能的更全面的討論，以及一些更多的使用例子。

::::HASHNUM.BAT history
::::
:::: v1.4 2016-12-26 - Convert /A value to upper case because some Windows
:::: versions are case sensitive. Also improve JScript file
:::: read performance by reading 1000000 bytes instead of 1.
:::: v1.3 2016-12-17 - Bug fixes: Eliminate unwanted \r\n from temp file by
:::: reading stdin with JScript instead of FINDSTR.
:::: Fix help to ignore history.
:::: v1.2 2016-12-07 - Bug fixes: Exclude FORFILES directories and
:::: correct setlocal/endlocal management in :getOptions
:::: v1.1 2016-12-06 - New /V option, and minor bug fixes.

:::
:::HASHSUM [/Option [Value]]... [File]...
:::
::: Print or check file hashes using any of the following standard
::: hash algorithms: MD5, SHA1, SHA256, SHA384, or SHA512.
:::
::: HASHSUM always does a binary read - \r\n is never converted to \n.
:::
::: In the absence of /C, HASHSUM computes the hash for each File, and writes
::: a manifest of the results. Each line of output consists of the hash value,
::: followed by a space and an asterisk, followed by the File name. The default
::: hash alogrithm is sha256. File may include wildcards, but must not contain
::: any path information.
:::
::: If File is not given, then read from standard input and write the hash
::: value only, without the trailing space, asterisk, or file name.
:::
::: Options:
:::
::: /? - Prints this help information to standard output.
:::
::: /?? - Prints paged help using MORE.
:::
::: /V - Prints the HASHNUM.BAT version.
:::
::: /A Algorithm
:::
::: Specifies one of the following hash algorithms:
::: MD5, SHA1, SHA256, SHA384, SHA512
:::
::: /P RootPath
:::
::: Specifies the root path for operations.
::: The default is the current directory.
:::
::: /S - Recurse into all Subdirectories. The relative path from the root
::: is included in the file name output.
::: This option is ignored if used with /C.
:::
::: /I - Include the RootPath in the file name output.
::: This option is ignored if used with /C.
:::
::: /T - Writes a space before each file name, rather than an
::: asterisk. However, files are still read in binary mode.
::: This option is ignored if used with /C.
:::
::: /C - Read hash values and file names from File (the manifest), and verify
::: that local files match. File may include path information with /C.
:::
::: If File is not given, then read hash and file names from standard
::: input. Each line of input must have a hash, followed by two spaces,
::: or a space and an asterisk, followed by a file name.
:::
::: If /A is not specified, then the algorithm is determined by the
::: File extension. If the extension is not a valid algorithm, then
::: the algorithm is derived based on the length of the first hash
::: within File.
:::
::: Returns ERRORLEVEL 1 if any manifest File is not found or is invalid,
::: or if any local file is missing or does not match the hash value in
::: the manifest. If all files are found and match, then returns 0.
:::
::: /NE - (No Errors) Suppresses error messages when using /C.
:::
::: /NM - (No Matches) Suppresses listing of matching files when using /C.
:::
::: /NS - (No Summary) Suppresses summary information when using /C.
:::
::: /Q - (Quiet) Suppresses all output when using /C.
