## Introduction
VirgilCrypto is a stack of security libraries (ECIES with Crypto Agility wrapped in Virgil Cryptogram) and an open-source high-level [cryptographic library](https://github.com/VirgilSecurity/virgil-crypto) that allows you to perform all necessary operations for securely storing and transferring data in your digital solutions. Crypto Library is written in C++ and is suitable for mobile and server platforms.
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.
## Library purposes
* Asymmetric Key Generation
* Encryption/Decryption of data and streams
* Generation/Verification of digital signatures
* PFS (Perfect Forward Secrecy)
## Usage examples
#### Generate a key pair
Generate a Private Key with the default algorithm (EC_X25519):
```cs
using Virgil.Crypto;
var crypto = new VirgilCrypto();
var keyPair = crypto.GenerateKeys();
```
#### Generate and verify a signature
Generate signature and sign data with a private key:
```cs
using Virgil.Crypto;
var crypto = new VirgilCrypto();
// prepare a message
var messageToSign = "Hello, Bob!";
var dataToSign = Encoding.UTF8.GetBytes(messageToSign);
// generate a signature
var signature = crypto.GenerateSignature(dataToSign, senderPrivateKey);
```
Verify a signature with a public key:
```cs
using Virgil.Crypto;
var crypto = new VirgilCrypto();
// verify a signature
var verified = crypto.VerifySignature(signature, dataToSign, senderPublicKey);
```
#### Encrypt and decrypt data
Encrypt Data on a Public Key:
```cs
using Virgil.Crypto;
var crypto = new VirgilCrypto();
// prepare a message
var messageToEncrypt = "Hello, Bob!";
var dataToEncrypt = Encoding.UTF8.GetBytes(messageToEncrypt);
// encrypt the message
var encryptedData = crypto.Encrypt(dataToEncrypt, receiverPublicKey);
```
Decrypt the encrypted data with a Private Key:
```cs
using Virgil.Crypto;
var crypto = new VirgilCrypto();
// prepare data to be decrypted
var decryptedData = crypto.Decrypt(encryptedData, receiverPrivateKey);
// decrypt the encrypted data using a private key
var decryptedMessage = Encoding.UTF8.GetString(decryptedData);
```
