Systems and methods for executing cryptographic operations across different types of processing hardware

A method for executing handshake operations across different types of processing hardware, the method comprising:

• identifying, by a device intermediary to a client and a server, from a plurality of handshakes, a handshake to be performed by the device based on at least a type of a message from the client or the server, the plurality of handshakes comprising a secure socket layer handshake (SSL) or a transport layer security (TLS) handshake;
• generating, by the device, a sequence of handshake operations to be executed for performing the handshake identified from the plurality of cryptographic functions based on at least the type of the message;
• determining, by the device, from the generated sequence of handshake operations, a first subset of the handshake operations to be executed on a first type of processing hardware and a second subset of the handshake operations to be executed on a second type of processing hardware different from the first type to carry out the sequence of handshake operations for performing the handshake, the first and the second types of processing hardware residing on the device;
• and
• instructing, by the device responsive to the determination, the first type and the second type of processing hardware to execute the first subset and the second subset of the handshake operations respectively, according to the sequence of the cryptographic operations for performing the handshake.
