Methods and apparatus to hash data

A non-transitory machine-readable medium having instructions stored thereon to be executed on one or more processors in a computer system to enable the computer system to:

• split the data item into a plurality of chunks having a fixed size;
• generate a message schedule to be applied to at least two of the chunks;
• and
• employ the message schedule for computing a plurality of rounds, each compressing two or more chunks, to generate a hash.

A computer system comprising:

• memory, in which a plurality of software instructions are loaded or stored;
• and
• one or more processors, operatively coupled to the memory,
• wherein execution of the software instructions on the one or more processors enables the computing system to,
• split the data item into a plurality of chunks having a fixed size;
• generate an SHA-2 (Secure Hash Algorithm 2) message schedule to be applied to at least two of the chunks;
• and
• employ the SHA-2 message schedule for computing a plurality of SHA-2 rounds, each compressing two or more chunks, to generate a hash.
