what base64 encoding

If you use the Base64_encode and Base64_decode methods directly, the resulting string may not be applicable to the URL address. The following methods can be used to resolve the problem:URL-safe string encoding: function Urlsafe_b64encode ($string) {$

PHP-safe URL string base64 encoding and decoding. If base64_encode and base64_decode are used directly, the generated string may not apply to the URL address. The following method can solve this problem: URL-safe string encoding: if base64_encode

The process of converting a picture to a Base64 string is to first serialize the picture file into binary data using BinaryFormatter, and then use the ToBase64String method of the Convert class. The process of converting a Base64 string to a picture

In the Delphi 10.1 Berlin version, there are several Base64 encoded units that can be used, such as Indy, Messagedigest_5, and CnBase64, which I now use with my own system.netencoding.var string; Digest:tbytes; base64:tbase64encoding; begin

The following is a detailed description of how BASE64 is encoded.The so-called Base64, that is to choose 64 characters----lowercase letter A-Z, uppercase letter A-Z, number 0-9, the symbol "+", "/" (plus the "=" as the pad word, is actually 65

I. ORIGIN of BASE64 coding Why would there be Base64 code? Because some network transport channels do not support all bytes, for example, traditional messages only support the transfer of visible characters, such as ASCII code control characters

BASE64 can be used to encode binary byte sequence data into text consisting of an ASCII character sequence. The complete BASE64 definition is visible RFC1421 and RFC2045. The encoded data is slightly longer than the original data, which is 4/3 of
