Base64関数

本ページには広告が含まれています。

文字列をBASE64にエンコード・デコードします。

BASE64とは、バイナリデータを一定の規則に基づいてテキスト(文字)データに置き換える変換方式の一つで、64種類の英数字のみを用いてデータを表現する方式。 電子メールの添付ファイル(MIME)などでよく用いられます。

構文
  1. UString = Base64.encodestr( str )
  2. UString = Base64.decodestr( str )
引数
str 必須
encodestr
エンコードしたい文字列
decodesr
デコードしたい文字列
戻り値
Base64.encodestr
エンコードした文字列
Base64.decodestr
