BASE64算法基于C++实现

1.参与生成的字符表

const wchar_t alph[] =
{
	'A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P','Q','R','S','T','U','V','W','X','Y','Z',
	'a','b','c','d','e','f','g','h','i','j','k','l','m','n','o','p','q','r','s','t','u','v','w','x','y','z',
	'0','1','2','3','4','5','6','7','8','9',CHAR_63,CHAR_64
};

包含26个大写字母与26个小写字母与数字与+/两个符号

2.符号定义

const wchar_t CHAR_63 = '+';
const
