我需要在Mac上對數據進行數字簽名,然後在iOS上驗證它。所以我用DER格式生成RSA密鑰對和公開密鑰證書,並打開ssl(嘗試使用SecKeyGeneratePair生成,但難以導入公鑰到iOS,而SecKeyRawVerify仍然無法使用相同結果),並在我的數據上簽名Mac應用程序。然後,如果我在iOS上驗證此數據,驗證失敗並顯示-9809錯誤代碼,但是如果在mac驗證上執行相同的代碼,則成功。SecKeyRawVerify在mac上驗證但在iOS上失敗-9809
這裏是我的驗證碼:
NSString* certPath = [[NSBundle mainBundle] pathForResource: @"Public" ofType:@"der"];
NSData* certificateData = [NSData dataWithContentsOfFile: certPath];
SecCertificateRef certificateFromFile = SecCertificateCreateWithData(NULL, (__bridge CFDataRef)certificateData); // load the certificate
SecPolicyRef secPolicy = SecPolicyCreateBasicX509();
SecTrustRef trust;
OSStatus statusTrust = SecTrustCreateWithCertificates(certificateFromFile, secPolicy, &trust);
SecTrustResultType resultType;
OSStatus statusTrustEval = SecTrustEvaluate(trust, &resultType);
SecKeyRef publicKey = SecTrustCopyPublicKey(trust);
NSString* licensingPolicyString = @"ZKL3YXtqtFcIeWRqSekNuCmtu/nvy3ApsbJ+8xad6cO/E8smLHGfDrTQ3h/38d0IMJcUThsVMyX8qtqILmPeTnBpZgJetBjb8kAfuPznzxOrIcYd27/50ThWv6guLqZL7j1apnfRZHAdMiozvEYH62sma1Q9qTl+W7qxEAxWs2AXDTQcF7nGciEM6MEohs8u879VNIE1VcPW8ahMoe25wf8pvBvrzE0z0MR4UFE3ZSWIeeQsiaUPYFwHbfQAOifaw/qIisjL5Su6WURoaSupWTMdQh3ZNyqZuYJaT70u8S7NgF3BzG8uBiYOUYsf6UayvkABmF0UuMdcvhPQefyhuXsiYWxsb3dFeGNoYW5nZSI6dHJ1ZSwiYWxsb3dTaGFmZXIiOnRydWUsInBvbGljeSBuYW1lIjp0cnVlfQ==";
size_t signedHashBytesSize = SecKeyGetBlockSize(publicKey);
NSData* messageData = [[NSData alloc] initWithBase64EncodedData:[licensingPolicyString dataUsingEncoding: NSUTF8StringEncoding] options:0];
NSData* signatureData = [messageData subdataWithRange:NSMakeRange(0, signedHashBytesSize)];
NSData* rawMessageData = [messageData subdataWithRange: NSMakeRange(signedHashBytesSize, messageData.length - signedHashBytesSize)];
uint8_t sha1HashDigest[CC_SHA1_DIGEST_LENGTH];
CC_SHA1([rawMessageData bytes], (CC_LONG)[rawMessageData length], sha1HashDigest);
OSStatus verficationResult = SecKeyRawVerify(publicKey, kSecPaddingPKCS1SHA1, sha1HashDigest, CC_SHA1_DIGEST_LENGTH, [signatureData bytes], [signatureData length]);
CFRelease(publicKey);
CFRelease(trust);
CFRelease(secPolicy);
CFRelease(certificateFromFile);
if (verficationResult == errSecSuccess) NSLog(@"Verified");
是否有適用於Mac和iOS在數字簽名驗證一些區別?我沒有在蘋果的文檔中找到任何有關它的信息。
即使更改填充,我也有同樣的問題。你是如何在OS X上籤署數據的?你是否使用變換明確地設置了填充? 'SecTransformSetAttribute(簽名者, kSecPaddingKey, kSecPaddingPKCS1Key, &錯誤);' – Maurizio
我直接在'SecKeyRawSign(privateKeyRef, kSecPaddingPKCS1設置填充, (常量uint8_t *)[[自getHashBytes:明文]字節], CC_SHA1_DIGEST_LENGTH , (uint8_t *)signedHashBytes, &signedHashBytesSize );'和'SecKeyRawVerify'中的相同 –
