Virgil Security Objective-C/Swift Crypto Library
This library is designed to be a small, flexible and convenient wrapper for a variety of crypto algorithms. So 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 requirement for developers to have a strong cryptographic skills.
Virgil Security, Inc., guides software developers into the forthcoming security world in which everything will be encrypted (and passwords will be eliminated). In this world, the days of developers having to raise millions of dollars to build a secure chat, secure email, secure file-sharing, or a secure anything have come to an end. Now developers can instead focus on building features that give them a competitive market advantage while end-users can enjoy the privacy and security they increasingly demand.
- Asymmetric Key Generation
- Encryption/Decryption of data
- Generation/Verification of digital signatures
- Crypto for using VirgilSDK
Generate a key pair
Generate a Private Key with 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 on 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)!

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', '~> 5.3.0' 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" ~> 5.3.0
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.
