Contract for objects that implement decryption.
An interface for an object provided by an application to decrypt content of encrypted models.
Content is encrypted with the AES128
algorithm in the CBC
mode.
A key is derived with the PBKDF2
algorithm by applying the HMAC
-SHA256
function 10,000 times.
