What is Cryptographic Primitive in Blockchain?

WebA basic construction used within many cryptographic systems is envelope encryption. Envelope encryption uses two or more cryptographic keys to secure a message. Typically, one key is derived from a longer-term static key k, and another key is a per-message key, msgKey, which is generated to encrypt the message.
