Methods and apparatus are provided for implementing a cryptography accelerator for performing operations such as hash operations. The cryptography accelerator recognizes characteristics associated with input data and retrieves an instruction set for processing the input data. The instruction set is used to configure or control components such as MD5 and SHA-1 hash cores, XOR components, memory, etc. By providing a cryptography accelerator with access to multiple instruction sets, a variety of hash operations can be performed in a configurable cryptographic accelerator.

Methods and apparatus performing hash operations in a cryptography accelerator

Methods and apparatus are provided for an entity such as a CPU to efficiently call a cryptography accelerator to perform cryptographic operations. A function call causes the cryptography accelerator to execute multiple cryptographic operations in a manner tailored for specific processing steps, such as steps during a handshake phase of a secured session. The techniques provide efficient use of hardware processing resources, data interfaces, and memory interfaces.
