Windows 相当于 linux cksum 命令

Question

我正在寻找一种计算 crc 校验和跨平台的方法。

cksum适用于 Linux、AIX、HP-UX Itanium、Solaris，在 Windows 中是否也有等效的 linux cksum命令？

%cksum run.sh
1491301976 652 run.sh

注意：没有第三方工具

Answer 1

在 Windows（命令提示符）中，您可以使用 CertUtil，语法如下：

CertUtil [Options] -hashfile InFile [HashAlgorithm]

对于 cmd 中的语法解释类型：

CertUtil -hashfile -?

例子：

CertUtil -hashfile C:\myFile.txt MD5

默认为 SHA1，它支持：MD2、MD4、MD5、SHA1、SHA256、SHA384、SHA512。 不幸的是，没有像 Unix shell 那样的 CRC32。

Answer 2

看起来好像有一个不受支持的 MS 校验和工具。 它的功能很简单，但似乎可以满足您的要求。 它于 2012 年 8 月发布。它被称为“Microsoft File Checksum Integrity Verifier”。

Answer 3

为避免烦人的非校验和行： CertUtil -v -hashfile "your_file" SHA1 | FIND /V "CertUtil" 这将只显示不包含CertUtil 的行

Answer 4

打开 Windows PowerShell，并使用以下命令：

Get-FileHash C:\Users\Deepak\Downloads\ubuntu-20.10-desktop-amd64.iso

Answer 5

这是用于 Windows 的 *nix cksum 命令行实用程序的 C# 实现https://cksum.codeplex.com/

Answer 6

2019 年，Microsoft 为 Windows 10 提供了以下解决方案。该解决方案适用于 SHA256 校验和。

https://docs.microsoft.com/en-us/powershell/module/microsoft.powershell.utility/get-filehash?view=powershell-6

按 Windows 键。 键入 PowerShell。 选择 Windows Powershell。 按回车键。 粘贴命令

Get-FileHash C:\\Users\\Donald\\Downloads\\File-to-be-checked-by-sha256.exe | 格式列表

将 File-to-be-checked-by-sha256.exe 替换为要检查的文件的名称。

将路径替换为文件所在的路径。 按回车键。 Powershell显示以下内容

算法：SHA256 哈希：123456789ABCDEFGH1234567890...路径：C:\\Users\\Donald\\Downloads\\File-to-be-checked-by-sha256.exe

Answer 7

结合@Cassian 和@Hllitec 的答案以及来自https://stackoverflow.com/a/42706309/1001717的答案，这里是我的解决方案，我将（仅！）校验和值放入变量中以进行进一步处理：

for /f "delims=" %i in ('certutil -v -hashfile myPackage.nupkg SHA256 ^| find /i /v "sha256" ^| find /i /v "certutil"') do set myVar=%i

要测试输出，您可以使用 var 添加管道回显命令：

for /f "delims=" %i in ('certutil -v -hashfile myPackage.nupkg SHA256 ^| find /i /v "sha256" ^| find /i /v "certutil"') do set myVar=%i | echo %myVar%

有点跑题，但仅供参考：我在将 NuGet 包上传到 Artifactory 之前使用了它。 顺便提一句。 作为替代方案，您可以使用 JFrog CLI，它会自动计算校验和。

linux中的cksum命令算法https://www.opennet.ru/man.shtml?topic=cksum&category=1&russian=5

Powershell 实现：

function UNSIGNED($u) {
    return $u -band 0xffffffff
}

function memcrc32($b){
