Apple证书无效,PKCS7_verify

Question

我下载了AppleRootCertificate.cer,现在我尝试检查我的应用程序内收据证书是否有效(与苹果一样).

我喜欢他的WWDS视频中的苹果.

    BIO *b_receipt = BIO_new_mem_buf((void *)[receipt bytes], (long)[receipt length]);
    BIO *b_x509 = BIO_new_mem_buf((void *)[certificateData bytes], (long)[certificateData length]);

    // Convert receipt data to PKCS #7 Representation
    PKCS7 * p7 = d2i_PKCS7_bio(b_receipt, NULL);

    // Create the certificate store for matching white Apple cerif.
    X509_STORE * store = X509_STORE_new();
    X509 * appleRootCA = d2i_X509_bio(b_x509, NULL);
    X509_STORE_add_cert(store, appleRootCA);

    // Verify the Signature

    BIO * b_receiptPayload = BIO_new(BIO_s_mem());
    int result = PKCS7_verify(p7, NULL, store, NULL, b_receiptPayload, 0);
    NSLog(@"Result == %i", result); 

但结果始终为0而不是1.

我做错了什么？

Answer 1

正如#noloader所建议我打印错误ERR_get_error().

当我得到:Error:0D0C50A1:lib(13):func(197):reason(161),我谷歌它发现我需要在上面添加这一行:

 OpenSSL_add_all_algorithms();

这解决了我所有的问题:D
