Abstract
Techniques for hashing messages with cryptographic key components are provided. In one technique, a message to be hashed with a private key component is identified. During a hash operation relative to the message involving a hash function, the client identifies an internal state of the hash function, which internal state is based on the message. The client sends the internal state of the hash function to a cryptographic device. The cryptographic device identifies a private key component and generates a final hash based on the private key component and the internal state of the hash function. In another technique, a client receives, from a cryptographic device, an internal state of a hash function, where the internal state is based on a private key component that is stored in the cryptographic device. Based on the internal state and a message, the client generates a final hash.
