【PowerShell】文字列のハッシュ値を得る

MemoryStreamクラスとStreamWriterクラスを使いストリームを作成し、Get-FileHashコマンドレットを使う。

PS > $ss = [System.IO.MemoryStream]::new()
PS > $sw = [System.IO.StreamWriter]::new($ss)
PS > $sw.write("鈴木みのり")
PS > $sw.Flush()
PS > $ss.Position = 0
PS > Get-FileHash -InputStream $ss -Algorithm MD5 | Select-Object Hash
Hash
