Systems, methods, and apparatuses relating to circuitry to implement an instruction to create and/or use data that is restricted in how it can be used are described. In one embodiment, a hardware processor comprises a decoder of a core to decode a single instruction into a decoded single instruction, the single instruction comprising a first input operand of a handle including a ciphertext of an encryption key (e.g., cryptographic key), an authentication tag, and additional authentication data, and a second input operand of data encrypted with the encryption key, and an execution unit of the core to execute the decoded single instruction to: perform a first check of the authentication tag against the ciphertext and the additional authentication data for any modification to the ciphertext or the additional authentication data, perform a second check of a current request of the core against one or more restrictions specified by the additional authentication data of the handle, decrypt the ciphertext to generate the encryption key only when the first check indicates no modification to the ciphertext or the additional authentication data, and the second check indicates the one or more restrictions are not violated, decrypt the data encrypted with the encryption key to generate unencrypted data, and provide the unencrypted data as a resultant of the single instruction.
