The result should be in accordance with ISO 3309, [http://www.itu.int/rec/T-REC-V.42-200203-I/en ITU-T V.42], [http://tools.ietf.org/html/rfc1952 Gzip] and [http://www.w3.org/TR/2003/REC-PNG-20031110/ PNG]. Algorithms are described on [[wp:Cyclic redundancy check|Computation of CRC]] in Wikipedia. This variant of CRC-32 uses LSB-first order, sets the initial CRC to FFFFFFFF16, and complements the final CRC. For the purpose of this task, generate a CRC-32 checksum for the ASCII encoded string: :: The quick brown fox jumps over the lazy dog
