如何将文本文件中的字符串转换为md5。谢谢

例如：

如果您想要的是整个文件的MD5哈希，只需执行

(Get-FileHash -Path 'X:Somewherethefile.txt' -Algorithm MD5).Hash

但是，如果您想为文件中的每一行文本获取MD5哈希值，还需要做更多的工作，因为get-FileHash不适用于单个字符串。然而，它确实可以与流一起工作，所以你可以利用它：

$stream = [System.IO.MemoryStream]::new()
$writer = [System.IO.StreamWriter]::new($stream)
$result = Get-Content -Path 'X:Somewherethefile.txt' | ForEach-Object {
$writer.Write($_)
$writer.Flush()
$stream.Position = 0
# output an object containing the string itself and the calculated MD5
[PsCustomObject]@{
String = $_
MD5    = (Get-FileHash -InputStream $stream -Algorithm MD5).Hash
}
$stream.SetLength(0)
}
$writer.Dispose()
$stream.Dispose()
# show on screen
$result
# or write to csv file
$result | Export-Csv -Path 'X:SomewhereStringsAndHashValues.csv' -NoTypeInformation

屏幕输出：

String     MD5                             
------     ---
