Crypto Library is written in C++ and is suitable for mobile and server platforms. Library purposes ---------------- [](#library-purposes) - Asymmetric Key Generation - Encryption/Decryption of data and streams - Generation/Verification of digital signatures - Double Ratchet algorithm support - **Post-quantum algorithms support**: [Round5](https://round5.org/) (encryption) and [Falcon](https://falcon-sign.info/) (signature) - Crypto for using [Virgil Core SDK](https://github.com/VirgilSecurity/virgil-sdk-php) Installation ------------ [](#installation) **Requirements**: - PHP 8.2, 8.3 #### Installation via composer [](#installation-via-composer) ``` composer require virgil/crypto ``` Usage examples -------------- [](#usage-examples) ### Generate a key pair [](#generate-a-key-pair) Generate a key pair using the default algorithm (EC\_X25519): ``` $crypto = new VirgilCrypto(); $keyPair = $crypto->generateKeyPair(); ``` ### Generate and verify a signature [](#generate-and-verify-a-signature) Generate signature and sign data with a private key: ``` $crypto = new VirgilCrypto(); $senderKeyPair = $crypto->generateKeyPair(); // prepare a message $messageToSign = "Hello, Bob!"; // generate a signature $signature = $crypto->generateSignature($messageToSign, $senderKeyPair->getPrivateKey()); ``` Verify a signature with a public key: ``` $crypto = new VirgilCrypto(); $senderKeyPair = $crypto->generateKeyPair(); // prepare a message $messageToSign = "Hello, Bob!"; // generate a signature $signature = $crypto->generateSignature($messageToSign, $senderKeyPair->getPrivateKey()); // verify a signature $verified = $crypto->verifySignature($signature, $messageToSign, $senderKeyPair->getPublicKey()); ``` ### Encrypt and decrypt data [](#encrypt-and-decrypt-data) Encrypt data with a public key: ``` $crypto = new VirgilCrypto(); $receiverKeyPair = $crypto->generateKeyPair(); // prepare a message $messageToEncrypt = "Hello, Bob!"; // encrypt the message $encryptedData = $crypto->encrypt($messageToEncrypt, new VirgilPublicKeyCollection($receiverKeyPair->getPublicKey())); ``` Decrypt the encrypted data with a private key: ``` $crypto = new VirgilCrypto(); $receiverKeyPair = $crypto->generateKeyPair(); // prepare a message $messageToEncrypt = "Hello, Bob!"; // encrypt the message $encryptedData = $crypto->encrypt($messageToEncrypt, new VirgilPublicKeyCollection($receiverKeyPair->getPublicKey())); // prepare data to be decrypted and decrypt the encrypted data using a private key $decryptedData = $crypto->decrypt($encryptedData, $receiverKeyPair->getPrivateKey()); ``` ### Import and export keys [](#import-and-export-keys) Export keys: ``` use Virgil\CryptoImpl\VirgilCrypto; $crypto = new VirgilCrypto(); $keyPair = $crypto->generateKeys(); // export private key $privateKeyData = $crypto->exportPrivateKey($keyPair->getPrivateKey(), "YOUR_PASSWORD"); $privateKeyStr = base64_encode($privateKeyData); // export public key $publicKeyData = $crypto->exportPublicKey($keyPair->getPrivateKey()); $publicKeyStr = base64_encode($publicKeyData); ``` Import keys: ``` use Virgil\CryptoImpl\VirgilCrypto; $crypto = new VirgilCrypto(); $privateKeyStr = "MIGhMF0GCSqGSIb3DQEFDTBQMC8GCSqGSIb3DQEFDDAiBBBtfBoM7VfmWPlvyHuGWvMSAgIZ6zAKBggqhkiG9w0CCjAdBglghkgBZQMEASoEECwaKJKWFNn3OMVoUXEcmqcEQMZ+WWkmPqzwzJXGFrgS/+bEbr2DvreVgEUiLKrggmXL9ZKugPKG0VhNY0omnCNXDzkXi5dCFp25RLqbbSYsCyw="; $privateKeyData = base64_decode($privateKeyStr); // import a Private key $privateKey = $crypto->importPrivateKey($privateKeyData, "YOUR_PASSWORD"); //----------------------------------------------------- $publicKeyStr = "MCowBQYDK2VwAyEA9IVUzsQENtRVzhzraTiEZZy7YLq5LDQOXGQG/q0t0kE="; $publicKeyData = base64_decode($publicKeyStr); // import a Public key $publicKey = $crypto->importPublicKey($publicKeyData); ``` Additional information ---------------------- [](#additional-information) - [Manually adding the crypto extension to your server](https://github.com/VirgilSecurity/virgil-cryptowrapper-php#additional-information) Docs ---- [](#docs) - [Crypto Core Library](https://github.com/VirgilSecurity/virgil-crypto) - [Developer Documentation](https://developer.virgilsecurity.com/) License ------- [](#license) This library is released under the [3-clause BSD License](LICENSE).

Uses a 2-year decay window. **Popularity (30%)** — Total and monthly downloads, GitHub stars, and forks. Logarithmic scaling prevents top-heavy scores. **Community (15%)** — Contributors, dependents, forks, watchers, and maintainers. Measures real ecosystem engagement. **Maturity (30%)** — Project age, version count, PHP version support, and release stability. ### Release Activity Cadence Every ~174 days Recently: every ~351 days Total 20 Last Release 641d ago Major Versions 1.4.0 → 2.0.02016-10-10 2.2.2 → v4.0.02018-05-09 v4.0.0 → v5.0.02018-05-14 v5.1.2 → v6.0.02020-04-02 v6.3.0 → v7.0.02024-09-30 PHP version history (6 changes)1.0.1PHP >=5.3 2.2.2PHP >=5.6 v6.0.0PHP ^7.2 v6.2.0PHP ^7.3|^8 v6.3.0PHP ^8.2 v7.0.0PHP ^8.3 ### Community Maintainers ![](https://www.gravatar.com/avatar/dbf68f51108fed58c83419750ce2961ab0e9a82577dde77fd387c5b5a0c60e69?d=identicon)[virgil](/maintainers/virgil) --- Top Contributors [![PetrenkoAnton](https://avatars.githubusercontent.com/u/24354013?v=4)](https://github.com/PetrenkoAnton "PetrenkoAnton (81 commits)")[![Qzich](https://avatars.githubusercontent.com/u/3338322?v=4)](https://github.com/Qzich "Qzich (30 commits)")[![sergey-ben](https://avatars.githubusercontent.com/u/1552870?v=4)](https://github.com/sergey-ben "sergey-ben (22 commits)")[![dsuhinin](https://avatars.githubusercontent.com/u/7852635?v=4)](https://github.com/dsuhinin "dsuhinin (20 commits)")[![SergeySeroshtan](https://avatars.githubusercontent.com/u/2228157?v=4)](https://github.com/SergeySeroshtan "SergeySeroshtan (13 commits)")[![MariiaMalitska](https://avatars.githubusercontent.com/u/37335222?v=4)](https://github.com/MariiaMalitska "MariiaMalitska (5 commits)")[![SanjoDeundiak](https://avatars.githubusercontent.com/u/6513916?v=4)](https://github.com/SanjoDeundiak "SanjoDeundiak (1 commits)") --- Tags cryptocryptographye2eeencryptionend-to-end-encryptiongdprhipaasecuritycryptographyencryptionAuthenticationplatformverificationcrossPasswordlessellipticdecryptionend-to-endvirgilECIESVirgil.KeysVirgil.PassPerfect Forward SecrecyPFS ### Code Quality TestsPHPUnit ### Embed Badge ![Health badge](/badges/virgil-crypto/health.svg) ``` [![Health](https://phpackages.com/badges/virgil-crypto/health.svg)](https://phpackages.com/packages/virgil-crypto) ``` ### Alternatives [virgil/sdk Virgil is a stack of security libraries (ECIES with Crypto Agility wrapped in Virgil Cryptogram) and all the necessary infrastructure to enable seamless, end-to-end encryption for any application, platform or device.
