Heimdall

In Norse mythology, Heimdall is the gatekeeper of Bifröst, the rainbow road connecting Midgard, realm of the humans, to Asgard, the realm of gods.

In iOS, Heimdall serves as a gatekeeper between Security framework and the UI, offering a nice wrapper around the C APIs for encrypting, decrypting, signing and verifying messages.

Furthermore, Heimdall also helps maintain the public-private RSA key-pair in Keychain, allowing both creating as well as deleting the key pairs.

Requirements

Heimdall requires Swift 3 and works with only Xcode 8 and above

Installation

CocoaPods

Heimdall is available as a CocoaPod, simply add the following line to your Podfile

pod 'Heimdall', '~> 1.1.0'

Also, make sure your podfile includes the following line, which is necessary to support Swift frameworks

use_frameworks!

Carthage

Simply include the following line in your Cartfile

github "henrinormak/Heimdall"

Note that Heimdall produces two frameworks in the Carthage build directory - Heimdall.framework and CommonCrypto.framework, you only need to include/embed Heimdall.framework into your project.

Subproject

As Heimdall makes use of CommonCrypto and has it wrapped in a pseudo-module, the easiest way to use Heimdall is to include the entire project as a subproject in your workspace.

To do this, include Heimdall.xcodeproj (found in Heimdall folder) into your Xcode workspace. Then specify the Heimdall target as a Target Dependency for your main application target.

Target Dependency selection in Xcode

Finally, make sure Heimdall is listed under the Embedded Binaries section in Xcode

Embedded Binaries under application target settings

Directly

Although not recommended, you can also add Heimdall directly, by including Heimdall.swift in your project.

Usage

Using Heimdall is simple, for public-private key-pair, you just have to create an instance, which can be used for encryption/decryption, signing/verifying.

With this method you can locally encrypt data to be stored on disk or in a database, without putting everything in the Keychain.

if let heimdall = Heimdall(tagPrefix: "com.example") {
    let testString = "This is a test string"

    // Encryption/Decryption
    if let encryptedString = heimdall.encrypt(testString) {
        println(encryptedString) // "cQzaQCQLhAWqkDyPoHnPrpsVh..."

        if let decryptedString = heimdall.decrypt(encryptedString) {
            println(decryptedString) // "This is a test string"
        }
    }

    // Signatures/Verification
    if let signature = heimdall.sign(testString) {
        println(signature) // "fMVOFj6SQ7h+cZTEXZxkpgaDsMrki..."
        var verified = heimdall.verify(testString, signatureBase64: signature)
        println(verified) // True

        // If someone meddles with the message and the signature becomes invalid
        verified = heimdall.verify(testString + "injected false message",
                                    signatureBase64: signature)
        println(verified) // False
    }
}

Note on encryption/decryption

As RSA imposes a limit on the length of message that can be enrcypted, Heimdall uses a mix of AES and RSA to encrypt messages of arbitrary length. This is done in the following manner:

  1. A random AES key of suitable length is generated, the length is based on the size of the RSA key pair (either 128, 192 or 256 bits) *
  2. The message is encrypted with this AES key
  3. The key is encrypted with the public part of the RSA key pair (and padded to the correct block size) *
  4. The payload is built, containing the encrypted key, followed by the encrypted message. During decryption, the first block is always assumed to be the RSA encrypted AES key, this is why Heimdall can only decrypt messages encrypted by other Heimdall instances (or code that is compatible with Heimdall's logic) *

Complex use case

A more complex use case involves exchanging encrypted messages between multiple Heimdall instances, which can be situated on multiple different hosts.

First step is to share your public key with another party:

let localHeimdall = Heimdall(tagPrefix: "com.example")
if let heimdall = localHeimdall, publicKeyData = heimdall.publicKeyDataX509() {

    var publicKeyString = publicKeyData.base64EncodedString()

    // If you want to make this string URL safe,
    // you have to remember to do the reverse on the other side later
    publicKeyString = publicKeyString.replacingOccurrences(of: "/", with: "_")
    publicKeyString = publicKeyString.replacingOccurrences(of: "+", with: "-")

    println(publicKeyString) // Something along the lines of "MIGfMA0GCSqGSIb3DQEBAQUAA..."

    // Data transmission of public key to the other party
}

Second step, acting as the recipient (the one that wants to send the encrypted message), you receive the public key extracted and create a matching Heimdall instance:

// On other party, assuming keyData contains the received public key data
if let partnerHeimdall = Heimdall(publicTag: "com.example.partner", publicKeyData: keyData) {
    // Transmit some message to the partner
    let message = "This is a secret message to my partner"
    let encryptedMessage = partnerHeimdall.encrypt(message)

    // Transmit the encryptedMessage back to the origin of the public key
}

Finally, having received the encrypted message, the party that sent out the public key can decrypt it using the original Heimdall instance they had:

// Initial host receives encryptedMessage
if let heimdall = localHeimdall {
    if let decryptedMessage = heimdall.decrypt(encryptedMessage) {
        println(decryptedMessage) // "This is a secret message to my partner"
    }
}

The workflow should be mirrored on all hosts, extracting their public keys and sharing those to all other parties. The public keys can be used to construct special Heimdall instances that are only able to encrypt messages and verify signatures.

Contributing and Current Work

Contributions to the codebase are very welcome, for ideas on what is needed, have a look through the open issues. In addition, any suggestions regarding the following topics are welcome:

  • Security, interacting with the Keychain, making sure the results are kept securely etc.
  • Tests, adding tests would also likely increase security
  • Additional configurability, perhaps allowing non-permanent keys
  • Error handling, currently most of the API simply returns nils whenever an error occurs, this should be changed and proper error reporting should be implemented
  • Reducing the number of optionals in the public API of the Heimdall instances.

  • Android Compatibility

    Android Compatibility

    Hello there, I'm working on exchanging encrypted data between my iOS and Android apps. Intra-platform communication is working perfectly for both iOS and Android. Now the exchange between iOS and Android is running into a decryption problem on the iOS side using Heimdall. I followed the Heimdall logic while writing the Android app as you can see below, but it seems some encoding or padding discrepancies caused the problem. Could any of the mentioned have caused the problem?

    String stringToShare = "Test String to Share";
        String userPublicKi = "MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEA1dOgSE2sPXDaHurcDygJsZojtA4HX3kV+2Msc0HpImSLpza5pJ5nz957Zp2XRprxImatAEx6kkKjII8PBKXyu74jEHqFP9ObzkDc/ZzhVk8/2xEUkAGokozM7SLp9US4lULJ0pXA1/MuVpZ20cGngJDYWVotSg90LbHAjVewVk497qLf9nK/UxoYzMpqWmPDjUCRQeNQVaMglSrRLTXcbWYlzm+MLlvbopagtF43nERlQ4e7xQRSS5k5EkeXOzOGCXNWMK/jTM3+cCIL2lGjWUWjMEZCIymv9nFBgeSPcDHiCjcWy25GfEJq6E5U4ke5YwLaYhxjWHXuVcdkefkTPwIDAQAB";

KeyGenerator keyGen = null;
        try {

            // Generate AES Random secret key
            keyGen = KeyGenerator.getInstance("AES");
            keyGen.init(256);
            SecretKeySpec secretKey = new SecretKeySpec(keyGen.generateKey().getEncoded(), "AES");

            // Get UTF8 encoded data from string to encrypt
            byte[] encodedData = serializedUserAccountToShare.getBytes("UTF-8");

            byte[] encryptedMessage = encryptAES(secretKey, encodedData);

            byte[] encryptedKey = encryptStringWithKey(new String(secretKey.getEncoded(), "UTF-8"), userPublicKi);

            ByteArrayOutputStream outputStream = new ByteArrayOutputStream( );
            outputStream.write(encryptedKey);

            // Testing part of the decryption on the Android side
            String decrypted = new String(decryptAES(secretKey.getEncoded(), encryptedMessage));

    and the functions I used in the process:

  • Improve AES encryption logic

    Improve AES encryption logic

    Two big changes, making sure initialisation vector is not null, indeed using random bytes that are stored along with the encrypted AES key.

    Second, make sure the AES key size is determined correctly, also leaving room for the included IV in the first block.

  • intermittent failure decrypting... (???)

    intermittent failure decrypting... (???)

    Not really sure how to perfectly describe my problem =(. I am using the latest version available via cocoapods and latest Swift. I am encrypting both text, e.g. String = "foo" and also images after base64 encoding them e.g. let _imageData = UIImageJPEGRepresentation(image, compressionFactor) let _encodedString = _imageData!.base64EncodedStringWithOptions(NSDataBase64EncodingOptions())

    I use a 2048 size key e.g. Heimdall(tagPrefix: key, keySize: 2048) and when I encrypt and decrypt I use urlEncode: false since the data is stored in a back end that doesn't need url encoding. I decrypt simply by: if let clearText = my_Heimdall_instance.decrypt(encrypted_text, urlEncoded: false) as String? { ...} So far so good. It's a chat application. it works great! except every now and again, seemingly without any pattern, decryption fails and returns nil. It's almost random and happens once every 20 to 100 messages. Sometimes with plain text messages, sometimes with images. I suspect some weird boundary condition (padding?) but I can't figure it out! The encrypted content looks normal and the length seems reasonable

    Any ideas?? [there may be a small reward for the first person to solve it!]

    Thanks! =)

    ps: FWIW, here is an example of an encrypted message that failed to decrypt. It's a few simple words as a String: jNCNYe8NPgqs3jspfGGiOwa/AkRb5PBWSp0FFvVdvMrMU50/0ti8j4SpYF+/OlcaeorpItuqEymU/mNB9PhHaV7IhxTPk8STcEs0o8KynHq1l7bHQ6gkHCMwhTxgNBeB+Mvctv5Pxxxg3+ESUmCKMH4G9+skC63Mamcm5BIRqokoL3lxnHaz77j0N09jP0rAkBY0jwN0myGrp2JV1cqLzzkWkTOYFkzgReMqRgrf3c2c9/vrRCPLk9umGGFq/YfCZXfpFja6C3OwPulgoKFxu/qX2hYAUZdJrZ0ao1/bL+xkSLvnOw/dXaR3FAxggFhzvbb/7+AVbnW3clvOF2gzLN05igEB6vxQuX0rQ9QLRop5hgR157LepY+EJtwBnSocPeYJ94MqoV0IeuFuevhuOXycAcyGwTHosdQX4pl7JzRs1oZR7wLJJgV4UDYF/uVXhp3X744+doefZsOvMnjddA==

  • Use the same PEM files for every Heimdall instance

    Use the same PEM files for every Heimdall instance

    Good day Henri,

    Thank you for responding to my tweet! I am trying to use the same PEM keys for every instance of Heimdall that I create. All I need to do is encrypt a timestamp with the PRIVATE key to make a simple signature. I haver the PEM of the Public key as well if I need it. I do not mind having to re-make the keys, but I definitely need the private key in a PEM format for the Android version (so if I generate a new key in a new format, I will need to make sure I can convert the new key to a PEM format as well).

    Could you please give me an example where the SAME key (preferably a set of PEM keys) are ALWAYS used in Heimdall and result in the same encrypted string? When I do the following:

        if let heimdall = Heimdall(tagPrefix: "www.example.com"){
        if let encryptedString = heimdall.encrypt("test") {
            print("Encrption: [\(encryptedString)]")
        } else {
            print("Encryption error")
        }
    } else {
        print("Init error")
    }

    I get a different String every time. I have tried putting the PEM Strings in as parameters:

        if let heim = Heimdall(publicTag: "...", privateTag: "...")

    but I get the same result - different Strings every time I run it.

  • Heimdall fails to decrypt it's own data after upgrading to Xcode 11/iOS 13 SDK

    Heimdall fails to decrypt it's own data after upgrading to Xcode 11/iOS 13 SDK

    The problem is simple but I'm having trouble reproducing it in a standalone project so I'm wondering if you have any ideas off the top of your head. I have a project that was previously building with Xcode 10.1 and used Heimdall to encrypt and decrypt data. After upgrading to Xcode 11, encryption still works but decryption does not. Or perhaps encryption reports a success but actually generates malformed data.

    Here is what I'm doing in my app. I have no idea why this works fine in a minimal example project but fails in my app. Maybe you've encountered similar when building with Xcode 11? Thanks in advance!

    let hd = Heimdall(publicTag: "pubTag", privateTag: "privTag")!
let encrypted = hd.encrypt("hello")!
let decrypted = hd.decrypt(encrypted)! // crash - decrypted string is nil

    Just to provide some more info. The input String is 5 bytes, but the Data returned from the internal call to self.decrypt is 16 bytes for some reason, and not a valid UTF-8 String which is why the method ultimately returns nil.

  • Add support for keychain access groups

    Add support for keychain access groups

    This PR adds support for keychain access group as a parameter when initializing an instance. This is most usable when using Heimdall with app extensions, for example: if one would have a messaging client where push notifications are bundled with data which is encrypted according to a key generated and saved by the "main app", an app extension could be used to decrypt the data using the same key before presenting the push notification.

  • Access option for RSA keypair in Keychain

    Access option for RSA keypair in Keychain

    Slightly refactored PR from #43. @colinmorelli, if possible, please review this. My main concern is the fact that the access flag can not be changed once set without regenerating the key. If this is a problem, then it needs to be addressed (for example, someone wanting to change the access as part of some switch in the app, without revoking the keypair).
