Virgil Crypto Library Objective-C/Swift
Virgil Crypto Library Objective-C/Swift is a small, flexible and convenient wrapper for a variety of crypto algorithms. It can be used in a small microcontroller as well as in a high load server application. Also, it provides a bunch of custom hybrid algorithms that combine different crypto algorithms to solve common complex cryptographic problems in an easy way. That eliminates a requirement for developers to have strong cryptographic skills.
- Asymmetric Key Generation
- Encryption/Decryption of data and streams
- Generation/Verification of digital signatures
- Double Ratchet algorithm support
- Post-quantum algorithms support: Round5 (encryption) and Falcon (signature)
- Crypto for using Virgil Core SDK
VirgilCrypto is provided as a set of frameworks. These frameworks are distributed via Carthage and CocoaPods.
All frameworks are available for:
- iOS 9.0+
- macOS 10.9+
- tvOS 9.0+
- watchOS 2.0+
CocoaPods is a dependency manager for Cocoa projects. You can install it with the following command:
$ gem install cocoapods
To integrate VirgilCrypto into your Xcode project using CocoaPods, specify it in your Podfile:
target '<Your Target Name>' do use_frameworks! pod 'VirgilCrypto', '~> 5.5.0' end
Then, run the following command:
$ pod install
Carthage is a decentralized dependency manager that builds your dependencies and provides you with binary frameworks.
You can install Carthage with Homebrew using the following command:
$ brew update $ brew install carthage
To integrate VirgilCrypto into your Xcode project using Carthage, create an empty file with name Cartfile in your project's root folder and add following lines to your Cartfile
github "VirgilSecurity/virgil-crypto-x" ~> 5.5.0
Linking against prebuilt binaries
To link prebuilt frameworks to your app, run following command:
$ carthage update
This will build each dependency or download a pre-compiled framework from github Releases.
Building for iOS/tvOS/watchOS
On your application target's “General” settings tab, in the “Linked Frameworks and Libraries” section, add following frameworks from the Carthage/Build folder inside your project's folder:
On your application target's “Build Phases” settings tab, click the “+” icon and choose “New Run Script Phase”. Create a Run Script in which you specify your shell (ex: /bin/sh), add the following contents to the script area below the shell:
and add the paths to the frameworks you want to use under “Input Files”, e.g.:
$(SRCROOT)/Carthage/Build/iOS/VirgilCrypto.framework $(SRCROOT)/Carthage/Build/iOS/VirgilCryptoFoundation.framework $(SRCROOT)/Carthage/Build/iOS/VSCCommon.framework $(SRCROOT)/Carthage/Build/iOS/VSCFoundation.framework
Building for macOS
On your application target's “General” settings tab, in the “Embedded Binaries” section, drag and drop following frameworks from the Carthage/Build folder on disk:
Additionally, you'll need to copy debug symbols for debugging and crash reporting on macOS.
On your application target’s “Build Phases” settings tab, click the “+” icon and choose “New Copy Files Phase”. Click the “Destination” drop-down menu and select “Products Directory”. For each framework, drag and drop the corresponding dSYM file.
Generate a key pair
Generate a private key using the default algorithm (EC_X25519):
import VirgilCrypto let crypto = try! VirgilCrypto() let keyPair = try! crypto.generateKeyPair()
Generate and verify a signature
Generate signature and sign data with a private key:
import VirgilCrypto let crypto = try! VirgilCrypto() // prepare a message let messageToSign = "Hello, Bob!" let dataToSign = messageToSign.data(using: .utf8)! // generate a signature let signature = try! crypto.generateSignature(of: dataToSign, using: senderPrivateKey)
Verify a signature with a public key:
import VirgilCrypto let crypto = try! VirgilCrypto() // verify a signature let verified = try! crypto.verifySignature(signature, of: dataToSign, with: senderPublicKey)
Encrypt and decrypt data
Encrypt data with a public key:
import VirgilCrypto let crypto = try! VirgilCrypto() // prepare a message let messageToEncrypt = "Hello, Bob!" let dataToEncrypt = messageToEncrypt.data(using: .utf8)! // encrypt the message let encryptedData = try! crypto.encrypt(dataToEncrypt, for: [receiverPublicKey])
Decrypt the encrypted data with a Private Key:
import VirgilCrypto let crypto = try! VirgilCrypto() // prepare data to be decrypted let decryptedData = try! crypto.decrypt(encryptedData, with: receiverPrivateKey) // decrypt the encrypted data using a private key let decryptedMessage = String(data: decryptedData, encoding: .utf8)!
Import and export keys
import VirgilCrypto // generate a Key Pair let crypto = VirgilCrypto() let keyPair = try! crypto.generateKeyPair() // export a Private key let privateKeyData = try! crypto.exportPrivateKey(keyPair.privateKey, password: "YOUR_PASSWORD") let privateKeyStr = privateKeyData.base64EncodedString() // export a Public key let publicKeyData = crypto.exportPublicKey(keyPair.publicKey) let publicKeyStr = publicKeyData.base64EncodedString()
import VirgilCrypto let crypto = VirgilCrypto() let privateKeyStr = "MIGhMF0GCSqGSIb3DQEFDTBQMC8GCSqGSIb3DQEFDDAiBBBtfBoM7VfmWPlvyHuGWvMSAgIZ6zAKBggqhkiG9w0CCjAdBglghkgBZQMEASoEECwaKJKWFNn3OMVoUXEcmqcEQMZ+WWkmPqzwzJXGFrgS/+bEbr2DvreVgEUiLKrggmXL9ZKugPKG0VhNY0omnCNXDzkXi5dCFp25RLqbbSYsCyw=" let privateKeyData = Data(base64Encoded: privateKeyStr)! // import a Private key let privateKey = try! crypto.importPrivateKey(from: privateKeyData, password: "YOUR_PASSWORD") //----------------------------------------------------- let publicKeyStr = "MCowBQYDK2VwAyEA9IVUzsQENtRVzhzraTiEZZy7YLq5LDQOXGQG/q0t0kE=" let publicKeyData = Data(base64Encoded: publicKeyStr)! // import a Public key let publicKey = try! crypto.importPublicKey(from: publicKeyData)
