将字节**转换为十六进制字符串：

# read the binary data as byte array
[byte[]]$data = [System.IO.File]::ReadAllBytes('D:\Test\blah.exe')

# write to new file as string of hex encoded characters
[System.IO.File]::WriteAllText('D:\Test\blah.hex',[System.BitConverter]::ToString($data).Replace('-',''), [System.Text.Encoding]::ASCII)

字符串
要转换回FROM十六进制字符串：

# read the textfile as single ASCII string
$hex = [System.IO.File]::ReadAllText('D:\Test\blah.hex', [System.Text.Encoding]::ASCII)

# convert to bytes and write these as new binary file
[System.IO.File]::WriteAllBytes('D:\Test\blahblah.exe', ($hex -split '(.{2})' -ne '' -replace '^', '0X'))

我的答案是基于@theo的https://stackoverflow.com/a/66303318/2394635，但有一些改进：

• 每个命令都是一行程序。
• 输入和输出文件可以直接传递给脚本
• 与其他PowerShell函数不同，它不需要文件之前就存在
• 兼容任何PowerShell版本，5或7

要将文件转换为十六进制字符串，请调用脚本：

# .\bin2hex.ps1 binfile hexfile
# write to new file as string of hex encoded characters
# $args[0] is binary, to $args[1] which is text
[.System.IO.File]::WriteAllText([io.path]::getfullpath([io.path]::combine($pwd.providerpath, $args[1])),[System.BitConverter]::ToString([byte[]][System.IO.File]::ReadAllBytes([io.path]::getfullpath([io.path]::combine($pwd.providerpath, $args[0])))).Replace('-',''), [System.Text.Encoding]::ASCII)

要将文件转换为十六进制字符串，只需执行以下命令：

[System.IO.File]::WriteAllText($ExecutionContext.SessionState.Path.GetUnresolvedProviderPathFromPSPath("file.hex"),[System.BitConverter]::ToString([byte[]][System.IO.File]::ReadAllBytes($ExecutionContext.SessionState.Path.GetUnresolvedProviderPathFromPSPath("file.bin"))).Replace('-',''), [System.Text.Encoding]::ASCII)

# convert to bytes and write these as new binary file
# $args[0] is text, to $args[1] which is binary
[System.IO.File]::WriteAllBytes([io.path]::getfullpath([io.path]::combine($pwd.providerpath, $args[1])), (([System.IO.File]::ReadAllText([io.path]::getfullpath([io.path]::combine($pwd.providerpath, $args[0])), [System.Text.Encoding]::ASCII)) -split '(.{2})' -ne '' -replace '^', '0X'))
