Someone asked for an example of decoding with OpenSSL on the Howto base64 encode with C/C++ and OpenSSL post. So here it is: #include <string.h> #include <openssl/sha.h> #include <openssl/hmac.h> #include <openssl/evp.h> #include <openssl/bio.h> #include <openssl/buffer.h> char *unbase64(unsigned char *input, int length); int main(int argc, char **argv) {   char *output = unbase64("WU9ZTyEA\n\0", strlen("WU9ZTyEA\n\0"));   printf("Unbase64: *%s*\n", output);   free(output); } char *unbase64(unsigned char *input, int length) {   BIO *b64, *bmem;   [...]
