PairedEncryptor

open class PairedEncryptor

This use case class performs an “encrypt” operation on some data, parametrized by a PairedSecurityKey.

ByteSecret sessionSecret = SecretGenerator.getInstance().createRandom(32);
byte[] encryptedSessionSecret = new PairedEncryptor(pairedSecurityKey).encrypt(sessionSecret);

The encryptedSessionSecret is typically stored in an EncryptedSessionStorage, to be able to later restore the sessionSecret using a PairedDecryptor.

The sessionSecret can be used for symmetric encryption operations, e.g. to encrypt a database. Once it has been deleted, it can only be restored from the encryptedSessionSecret when the paired security key is connected.
