Command line syntax

crc32 [-dec | -hex | -lowerhex] <file name>

Without options specified application shows CRC32 hash in both decimal and hexadecimal formats.

The following options are supported:

/dec - display CRC32 hash in decimal format (3281181382)

/hex - display CRC32 hash in uppercase hexadecimal format (C392DAC6)

/lowerhex - display CRC32 hash in lowercase hexadecimal format (c392dac6)

Examples:

crc32 filename.bin
crc32 -dec filename.bin
crc32 -hex filename.bin
crc32 -lowerhex filename.bin
