[英]`SecKey` object creation for RSA failing, Error Domain Code=-50 "RSA private key creation from data failed swift-iOS
I'm not able to create SecKey
object from below private key, I did try many answers available here but nothing is helping. 我无法从私钥下面创建SecKey
对象,我确实尝试了许多可用的答案,但没有任何帮助。
My swift piece of code is as below: 我的快速代码如下:
var error: Unmanaged<CFError>?
guard let keyData = Data(base64Encoded: key) else {
return nil
}
var keyAttributes: CFDictionary {
return [kSecAttrKeyType: kSecAttrKeyTypeRSA,
kSecAttrKeyClass: kSecAttrKeyClassPrivate,
kSecAttrKeySizeInBits: keySize] as CFDictionary
}
guard let secKey = SecKeyCreateWithData(keyData as CFData, keyAttributes, &error) else {
print(error.debugDescription) //Error Domain Code=-50 "RSA private key creation from data failed swift-iOS
return nil
}
The expected result is secKey
should have valid value and above guard
should not fail. 预期结果是secKey
应该具有有效值,并且上述guard
措施不应失败。
Note: Public key conversion to the respective secKey
is working perfectly fine (the problem is with the only private key while decryption). 注意:将公钥转换为相应的secKey
可以正常工作(问题在于解密时只有唯一的私钥)。 I have tried removing \\r\\n
from the above key. 我尝试从上述键中删除\\r\\n
。
After searching a lot, found this Apple thread helpful. 经过大量搜索后,发现此Apple线程很有帮助。 I'm able to manage this ASN.1 parsing using SwiftyRSA library. 我可以使用SwiftyRSA库管理此ASN.1解析。
let privateKeySwifty = try PrivateKey(pemEncoded: privateKey)
let secPrivateKey = try PrivateKey(reference: privateKeySwifty.reference)
After digging deeper, I can see, there was a need to stripe the header of keyData
( ASN.1 Parsing ). 深入研究之后,我看到,有必要keyData
的标题( ASN.1 Parsing )。
