Disclosed are various embodiments for executing entity-specific cryptographic code in a cryptographic coprocessor. In one embodiment, an exemplary method comprises transmitting, from an entity service to a client device, a key identifier and encrypted code that implements a cryptographic algorithm, wherein the encrypted code further includes an encryption key, wherein the key identifier identifies a particular root key that is associated with the entity service and is stored with a cryptographic coprocessor of the client device; receiving, by the entity service from the client device, a cryptogram that includes information encrypted using the cryptographic algorithm and the encryption key; and decrypting, by the entity service, the cryptogram using the encryption key.
