Virgil Security Ruby Crypto Library

VirgilCrypto is a stack of security libraries (ECIES with Crypto Agility wrapped in Virgil Cryptogram) and an open-source high-level cryptographic library 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.

• Asymmetric Key Generation
• Encryption/Decryption of data and streams
• Generation/Verification of digital signatures
• PFS (Perfect Forward Secrecy)

Generate a Private Key with the default algorithm (EC_X25519):

require 'virgil/crypto'
include Virgil::Crypto

crypto = VirgilCrypto.new
key_pair = crypto.generate_keys

Generate signature and sign data with a private key:

require 'virgil/crypto'
include Virgil::Crypto

crypto = VirgilCrypto.new

# prepare a message
message_to_sign = 'Hello, Bob!'
data_to_sign = Bytes.from_string(message_to_sign)

# generate a signature
signature = crypto.generate_signature(data_to_sign, sender_private_key)

Verify a signature with a public key:

require 'virgil/crypto'
include Virgil::Crypto

crypto = VirgilCrypto.new

# verify a signature
verified = crypto.verify_signature(signature, data_to_sign, sender_public_key)

Encrypt Data on a Public Key:

require 'virgil/crypto'
include Virgil::Crypto

crypto = VirgilCrypto.new

# prepare a message
message_to_encrypt = 'Hello, Bob!'
data_to_encrypt = Bytes.from_string(message_to_encrypt)

# encrypt the message
encrypted_data = crypto.encrypt(data_to_encrypt, receiver_public_key)

Decrypt the encrypted data with a Private Key:

require 'virgil/crypto'
include Virgil::Crypto

crypto = VirgilCrypto.new

# prepare data to be decrypted
decrypted_data = crypto.decrypt(encrypted_data, receiver_private_key)

# decrypt the encrypted data using a private key
decrypted_message = Bytes.new(decrypted_data).to_s
