base\Security encryptByKey()

encryptByKey() public method

Encrypts data using a cryptographic key.

Derives keys for encryption and authentication from the input key using HKDF and a random salt, which is very fast relative to encryptByPassword(). The input key must be properly random -- use generateRandomKey() to generate keys. The encrypted data includes a keyed message authentication code (MAC) so there is no need to hash input or output data.
