主要注意一下密钥的格式

#include <openssl/pem.h>#include <openssl/err.h>bool CEncipher::CreatePubKey(){    BIO* bp = NULL;    string strPublicKey = "MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQCmm9GRVbi5+myHYztzOyWvMdo1\                          4b0fwRF3va9A8bd19oW9ZUCpALVIC4d4I1Zvkfcgnpvswf/DOHD9umT+pevmwICF\                          /mU8LNe/MT8kGh0IAIHdJVrXw/2TEWCVEgFlFfloWzCNmzOcx4BH8yIw50RjG1ED\                          5Fl5QKFrirgcU11IhQIDAQAB";    int nPublicKeyLen = strPublicKey.size();    for(int i = 64; i < nPublicKeyLen; i+=64)    {        if(strPublicKey[i] != '\n')        {            strPublicKey.insert(i, "\n");        }        i++;    }    strPublicKey.insert(0, "-----BEGIN PUBLIC KEY-----\n");    strPublicKey.append("\n-----END PUBLIC KEY-----\n");    char *chPublicKey = const_cast<char *>(strPublicKey.c_str());    if ((bp = BIO_new_mem_buf(chPublicKey, -1)) == NULL)    {             printf("BIO_new_mem_buf failed!\n");        return false;    }    pPubKey_ = PEM_read_bio_RSA_PUBKEY(bp, NULL, NULL, NULL);    if (NULL == pPubKey_)    {        ERR_load_crypto_strings();        char errBuf[512];        ERR_error_string_n(ERR_get_error(), errBuf, sizeof(errBuf));        printf("load public key failed[%s]\n", errBuf);        return false;    }    BIO_free_all(bp);    return true;}
