URL-Safe Base64 Encoding

최신 업데이트:2022-03-01 18:00:57

URL-Safe Base64 Encoding is suitable for scenarios where Base64 encoded results are transferred with the URL method. The basic process of this encoding method is first encoding content into a character string in Base64 format, then checking the resultant character string, substituting hyphens (-) for the plus signs (+) in the character string, and substituting the underscores (_) for the forward slashes (/).
