Hybrid Encryption

• AES / RSA

We currently have no other libraries benchmark.

// Initializer creates our AES key, AES Nonce, and RSA Key Pair for us.
AESRSAHybridInitializer initializer = new AESRSAHybridInitializer(256, 4096);
AESRSAHybridEncryptResult result = this._hybridEncryptionWrapper.EncryptAESRSAHybrid(dataToEncrypt, initializer);
byte[] plaintext = this._hybridEncryptionWrapper.DecryptAESRSAHybrid(initializer.RsaKeyPair.PrivateKey, result);
