Base64系列第四篇 C/C++中使用Base64编码解码(从chromium库中抽取)

#include "./base64.h" #include <string.h> bool Base64Encode(const std::string& input, std::string* output) { std::string temp; temp.resize(modp_b64_encode_len(input.size())); // makes room for null byte // null terminates result since result is base64 text! int input_size = static_cast<int>(input.size()); int output_size= modp_b64_encode(&(temp[0]), input.data(), input_size); if (output_size < 0) return false; temp.resize(output_size); // strips off null byte output->swap(temp); return true; } bool Base64Decode(const std::string& input, std::string* output) { std::string temp; temp.resize(modp_b64_decode_len(input.size())); // does not null terminate result since result is binary data! int input_size = static_cast<int>(input.size()); int output_size = modp_b64_decode(&(temp[0]), input.data(), input_size); if (output_size < 0) return false; temp.resize(output_size); output->swap(temp); return true; }
