encrypt() публичный статический Метод

Encrypt a string using asymmetric cryptography Wraps SymmetricCrypto::encrypt()
public static encrypt ( HiddenString $plaintext, EncryptionSecretKey $ourPrivateKey, EncryptionPublicKey $theirPublicKey, mixed $encoding = Halite::ENCODE_BASE64URLSAFE ) : string
$plaintext HiddenString The message to encrypt
$ourPrivateKey EncryptionSecretKey Our private key
$theirPublicKey EncryptionPublicKey Their public key
$encoding mixed Which encoding scheme to use?
Результат string Ciphertext
