One embodiment provides an apparatus. The apparatus includes a single instruction multiple data (SIMD) hash module configured to apportion at least a first portion of a message of length L to a number (S) of segments, the message including a plurality of sequences of data elements, each sequence including S data elements, a respective data element in each sequence apportioned to a respective segment, each segment including a number N of blocks of data elements and to hash the S segments in parallel, resulting in S segment digests, the S hash digests based, at least in part, on an initial value and to store the S hash digests; a padding module configured to pad a remainder, the remainder corresponding to a second portion of the message, the second portion related to the length L of the message, the number of segments and a block size; and a non-SIMD hash module configured to hash the padded remainder, resulting in an additional hash digest and to store the additional hash digest. |
