digitalleaves / asymmetriccrypto Goto Github PK

Hello,

I just upgraded a project where we use AsymmetricCrypto to Swift 5 and we are now getting several warnings "withUnsafeMutableBytes is deprecated...", e.g.::

It would be great if you could handle this.

Thanks.

Hello,

I just upgraded to Swift 3 and also upgraded AssymetricCrypto. However, I am using getPublicKeyData which is now fileprivate so my code will not build. I can easily fix this by simply removing fileprivate, but I wanted to know if there is another way to get the public key data that I should be using. What I am currently doing:

AsymmetricCryptoManager.sharedInstance.createSecureKeyPair({ (success, error) in
   if success {
      let cryptoImportExportManager = CryptoExportImportManager()
      let publicKeyData = AsymmetricCryptoManager.sharedInstance.getPublicKeyData()
      publicKeyPem = cryptoImportExportManager.exportRSAPublicKeyToPEM(publicKeyData!, keyType: kSecAttrKeyTypeRSA as String, keySize: 2048)
                    
   } else {
      Log.error?.message("Error creating key pair: \(error.debugDescription)")
}

Perhaps you can remove fileprivate, unless there is a better way to do the above?

Thanks.

Hey Ignacio, I just stumbled upon your repo and find this to be a good wrapper for the Security framework. I noticed in your blog post that the license adopted for this code is the MIT license. Do you mind adding this to the repo for clarity? Cheers.

I wish to use my public key to decrypt a string but I can't find any way to do so.
The asymetric crypto uses a generator for the keys.

Is there any way to make it work with my keys?

Currently, i'm trying to implement this library to generate public key in my iOS device, and save it in my database through API.

When i send this public key from this library, i modify publicKeyData using https://github.com/DigitalLeaves/CryptoExportImportManager

But, when i encrypt from my backend (GoLang), and i tried to decode the encrypted message from my backend with this code:

   let encryptedData = Data(base64Encoded: encryptedMessage, options: [])
    
    AsymmetricCryptoManager.sharedInstance.decryptMessageWithPrivateKey(encryptedData!) { (success, result, error) -> Void in
        if success {
            print("result: \(result)")
        } else {
            print("Error decoding base64 string: \(error)")
        }
    }

it got error decoding base64 string: Optional(com.myProjects.AsymmetricCryptoException.unableToDecrypt)

After several research, i found, Golang encrypt using EncryptPKCS1v15 (https://github.com/golang/go/blob/master/src/crypto/rsa/pkcs1v15.go)
which make the iOS app failed to decrypt it because it only has PKCS1.

What should i do to decrypt with PKCS1v15 padding ?
