1.RSA非对称的,首先提供一个供测试用的证书和私钥的数据

因为尝试私钥没有导入成功,暂且不管,关于这一点待会再说验证交互成功的替换方案
2.先来看下openssl的RSA实现方案,openssl本身提供了许多的padding方式,
因为CryptoAPI只提供了PKCS1和OAEP两种补齐方式,默认使用的PKCS1,那这里就用PKCS1来验证吧

}
2)有了公钥,私钥对象,接下来做非对称加密和解密就简单些了
CryptoAPI的 默认补齐方式是PKCS1,我先以为就是NO_PADDING,结果发现CryptoAPI貌似就没有对NO_PADDING的支持
[cpp] view plaincopyprint?
void evelop(EVP_PKEY* evp_pubKey,BYTE ** out,unsigned int &cOut,const BYTE * in,unsigned int cIn){ OpenSSL_add_all_algorithms(); bool hasErr = true ; EVP_PKEY_CTX* ctx = EVP_PKEY_CTX_new(evp_pubKey,NULL); if (!ctx) goto err; if (EVP_PKEY_encrypt_init(ctx)<=0) goto err; if (EVP_PKEY_CTX_set_rsa_padding(ctx, RSA_PKCS1_PADDING) <= 0) goto err; if (EVP_PKEY_encrypt(ctx,NULL,&cOut,in,cIn)<=0) goto err; *out =(BYTE *) OPENSSL_malloc(cOut); if (!out) goto err; if (EVP_PKEY_encrypt(ctx,*out,&cOut,in,cIn)<=0) goto err; cout << "加密成功!" << endl; hasErr = false ; err: EVP_PKEY_CTX_free(ctx); if (!hasErr) return ; return ; } void develop(EVP_PKEY* priKey,BYTE ** out,unsigned int &cOut, BYTE * data,unsigned int cData){ OpenSSL_add_all_algorithms(); bool hasErr = true ; EVP_PKEY_CTX* ctx = EVP_PKEY_CTX_new(priKey,NULL); if (!ctx) goto err; if (EVP_PKEY_decrypt_init(ctx) <= 0) goto err; if (EVP_PKEY_CTX_set_rsa_padding(ctx, RSA_PKCS1_PADDING) <= 0) goto err; if (EVP_PKEY_decrypt(ctx, NULL, &cOut, data, cData) <= 0) goto err; *out =(BYTE *) OPENSSL_malloc(cOut); if (!out) goto err; if (EVP_PKEY_decrypt(ctx, *out, &cOut, data, cData) <= 0) goto err; hasErr = false ; err: EVP_PKEY_CTX_free(ctx); if (!hasErr) return ; cout << "err in develop" << endl; const char *file,*data1,*efunc,*elib,*ereason,*p; int line,flags; unsigned long errn; errn=ERR_peek_error_line_data(&file,&line,&data1,&flags); printf("ERR_peek_error_line_data err : %ld,file :%s,line :%d,data :%s\n" ,errn,file,line,data1); } void evelop(EVP_PKEY* evp_pubKey/*公钥对象*/,BYTE** out/*加密结果*/,unsigned int &cOut/*加密结果大小*/,const BYTE* in/*明文*/,unsigned int cIn/*明文大小*/){OpenSSL_add_all_algorithms();bool hasErr = true;EVP_PKEY_CTX* ctx = EVP_PKEY_CTX_new(evp_pubKey,NULL);if(!ctx)goto err;if(EVP_PKEY_encrypt_init(ctx)<=0)goto err;if (EVP_PKEY_CTX_set_rsa_padding(ctx, RSA_PKCS1_PADDING) <= 0)//设置补齐方式goto err;if(EVP_PKEY_encrypt(ctx,NULL,&cOut,in,cIn)<=0)//得到加密的长度,一般都是跟密钥一样长,1024位的RSA密钥就是128字节goto err;*out =(BYTE*) OPENSSL_malloc(cOut);if(!out)goto err;if(EVP_PKEY_encrypt(ctx,*out,&cOut,in,cIn)<=0)//得到加密结果goto err;cout << "加密成功!" << endl;hasErr = false;
err:EVP_PKEY_CTX_free(ctx);if(!hasErr)return;return;
}void develop(EVP_PKEY* priKey,BYTE** out,unsigned int &cOut, BYTE* data,unsigned int cData){OpenSSL_add_all_algorithms();bool hasErr = true;EVP_PKEY_CTX* ctx = EVP_PKEY_CTX_new(priKey,NULL);if(!ctx)goto err;if (EVP_PKEY_decrypt_init(ctx) <= 0)goto err;if(EVP_PKEY_CTX_set_rsa_padding(ctx, RSA_PKCS1_PADDING) <= 0)//与加密同样的PKCS1补齐goto err;if (EVP_PKEY_decrypt(ctx, NULL, &cOut, data, cData) <= 0)//解密结果大小goto err;*out =(BYTE*) OPENSSL_malloc(cOut);//分配内存if (!out)goto err;if (EVP_PKEY_decrypt(ctx, *out, &cOut, data, cData) <= 0)//得到解密结果goto err;hasErr = false;
err://输出一些错误信息,偶尔错误信息得不到,只得到一些文件名和所在行,就跑到源代码去找...麻烦死了,如果有好的方案求回复~EVP_PKEY_CTX_free(ctx);if(!hasErr)return;cout << "err in develop" << endl;const char*file,*data1,*efunc,*elib,*ereason,*p;int line,flags;unsigned long errn;errn=ERR_peek_error_line_data(&file,&line,&data1,&flags);printf("ERR_peek_error_line_data err : %ld,file :%s,line :%d,data :%s\n",errn,file,line,data1);}
3)自己测试下上面的代码吧,应该是没问题的
2.CryptoAPI的RSA非对称加密
[cpp] view plaincopyprint?
PCCERT_CONTEXT importCryptoCert(string base64Cert){ PCCERT_CONTEXT pCertContext = NULL; int len; BYTE * certEncoded = Base64::base64_decode(base64Cert,len); if (pCertContext = CertCreateCertificateContext( X509_ASN_ENCODING | PKCS_7_ASN_ENCODING, certEncoded, len)) { printf("A new certificate has been created.\n" ); } else { printf("A new certificate could not be created.\n" ); } return pCertContext; } PCCERT_CONTEXT importCryptoCert(string base64Cert){PCCERT_CONTEXT pCertContext = NULL; int len;BYTE* certEncoded = Base64::base64_decode(base64Cert,len);//BASE64解码,很多方式,先前博文中有代码if(pCertContext = CertCreateCertificateContext(X509_ASN_ENCODING | PKCS_7_ASN_ENCODING, certEncoded, len)) //直接就通过字节数组导入成证书上下文对象了{printf("A new certificate has been created.\n");}else{printf("A new certificate could not be created.\n");}return pCertContext;
}
little-endian 排列的字节数组,openssl则与其相反
CryptoAPI的说明,remark最后一句话,很小的字....
[cpp] view plaincopyprint?
void encryptByPubKey(HCRYPTPROV hProv,PCCERT_CONTEXT cert,BYTE * text,unsigned long &len){ HCRYPTKEY hKey; CERT_PUBLIC_KEY_INFO pubKeyInfo = cert->pCertInfo->SubjectPublicKeyInfo; if (!CryptImportPublicKeyInfoEx(hProv,X509_ASN_ENCODING,&pubKeyInfo,CALG_RSA_KEYX,0,NULL,&hKey)) { printf("CryptImportPublicKeyInfoEx error:0X%x.\n" ,GetLastError()); return ; } if (!CryptEncrypt(hKey,NULL,true ,0,text,&len,128)) { printf("CryptEncrypt error:0X%x.\n" ,GetLastError()); return ; } for (int i = 0 ; i < len / 2;i++) { BYTE temp = text[i]; text[i] = text[len - i - 1]; text[len - i - 1] = temp; } printByte(text,len); } void encryptByPubKey(HCRYPTPROV hProv,PCCERT_CONTEXT cert,BYTE* text,unsigned long &len){HCRYPTKEY hKey;CERT_PUBLIC_KEY_INFO pubKeyInfo = cert->pCertInfo->SubjectPublicKeyInfo;//拿到公钥信息if(!CryptImportPublicKeyInfoEx(hProv,X509_ASN_ENCODING,&pubKeyInfo,CALG_RSA_KEYX,0,NULL,&hKey))//导入,获取公钥对象{printf("CryptImportPublicKeyInfoEx error:0X%x.\n",GetLastError());return;}if(!CryptEncrypt(hKey,NULL,true,0,text,&len,128))//加密,padding参数为0,默认就是PKCS1的,不用管了,最后一个参数为128,是对于1024位RSA密钥,明文text得分配128个字节{printf("CryptEncrypt error:0X%x.\n",GetLastError());return;}
//以下将密文倒序,如果你在openssl倒序了,那这里就不用了,反正CryptoAPI和openssl本身的排列方式就是反的for(int i = 0 ; i < len / 2;i++){BYTE temp = text[i];text[i] = text[len - i - 1];text[len - i - 1] = temp;}printByte(text,len);
}
3.以上只试了CryptoAPI加密openssl解密,因为私钥没导入成功的关系,也没时间再去尝试了,暂且换一种替代方案来测试
如果CryptoAPI解密了CryptoAPI加密的,那这个也是等价的,那干脆直接从windows密钥库获取公私钥,用CryptoAPI直接做加密解密
[cpp] view plaincopyprint?
void decryptByPriKey(PCCERT_CONTEXT cert,BYTE * encText,unsigned long len){ for (int i = 0 ; i < len / 2;i++) { BYTE temp = encText[i]; encText[i] = encText[len - i - 1]; encText[len - i - 1] = temp; } HCRYPTPROV_OR_NCRYPT_KEY_HANDLE hKeyProv; DWORD *dwKeyType; BOOL bFreeKeyProv = FALSE; if (!CryptAcquireCertificatePrivateKey(cert, 0, 0, &hKeyProv, dwKeyType, &bFreeKeyProv)) { printf("CryptAcquireCertificatePrivateKey error:0X%x.\n" ,GetLastError()); return ; } HCRYPTKEY hKey; if (!CryptGetUserKey(hKeyProv,AT_KEYEXCHANGE,&hKey)) { printf("CryptGetUserKey error:0X%x.\n" ,GetLastError()); return ; } if (!CryptDecrypt(hKey,NULL,true ,0,encText,&len)){ printf("CryptDecrypt error:0X%x.\n" ,GetLastError()); return ; } printByte(encText,len); } void decryptByPriKey(PCCERT_CONTEXT cert,BYTE* encText,unsigned long len){//将结果再反序一次,用于CryptoAPI自己解密for(int i = 0 ; i < len / 2;i++){BYTE temp = encText[i];encText[i] = encText[len - i - 1];encText[len - i - 1] = temp;}HCRYPTPROV_OR_NCRYPT_KEY_HANDLE hKeyProv;DWORD *dwKeyType;BOOL bFreeKeyProv = FALSE; if(!CryptAcquireCertificatePrivateKey(cert, 0, 0, &hKeyProv, dwKeyType, &bFreeKeyProv)) //获取证书对应的私钥句柄{ printf("CryptAcquireCertificatePrivateKey error:0X%x.\n",GetLastError());return;} HCRYPTKEY hKey;if(!CryptGetUserKey(hKeyProv,AT_KEYEXCHANGE,&hKey))//通过句柄获取私钥对象{printf("CryptGetUserKey error:0X%x.\n",GetLastError());return;}if(!CryptDecrypt(hKey,NULL,true,0,encText,&len)){//解密,也可以把padding参数换成CRYPT_DECRYPT_RSA_NO_PADDING_CHECKprintf("CryptDecrypt error:0X%x.\n",GetLastError());return;}printByte(encText,len);
}
如果到此都没有什么问题,整个交互就算完成了.
