Base64 java字符串，带有。用c语言解码#

我从客户机中得到了以下字符串——它由基于java的SSO第三方组件的证书编码和签名

对于java到c#base64的转换，我知道需要将“-”替换为“+”，将“"”替换为“/”，如果需要，还需要添加额外的填充，在字符串末尾使用“=”，使其成为解码的正确长度-

解码可在以下位置完成：和

使用UTF-8编码

解码为

{"alg":"RS256","typ":"JWT"}

{"exp":1452051851,"iat":1452051791,"iss":"https://oauth/api/openid/v1/token","aud":"ea661167-a4b0-4d48-b0e1-5dc930399083","sub":"1d5fb0b7-7cc3-424d-853d-1a9acc386a39","at_hash":"Azvy-5BhGcA7A6R2j2A0ag","c_hash":"yw1t6zMqYSlNHM3BBbrzeg"}

及

解码为

哇，谢谢！-成功了，我以前应该测试一下
