[-a BITS] [-A OBITS] [-i INIT] [-k KPOLY] [-m MODEL] [-p POLY]
[-p POLY] [-P RPOLY] [-q QPOLY] [-w WIDTH] [-x XOROUT] [STRING...]
Options:
-a BITS bits per character (1 to 64)
-A OBITS bits per output character (1 to 64)
-i INIT initial register value
-k KPOLY generator in Koopman notation (implies WIDTH)
-m MODEL preset CRC algorithm
-p POLY generator or search range start polynomial
-P RPOLY reversed generator polynomial (implies WIDTH)
-q QPOLY search range end polynomial
-w WIDTH register size, in bits
-x XOROUT final register XOR value
Modifier switches:
-b big-endian CRC -B big-endian CRC output
-f read files named in STRINGs -F skip preset model check pass
-G skip brute force search pass -l little-endian CRC
-L little-endian CRC output -M non-augmenting algorithm
-r right-justified output -S print spaces between characters
-t left-justified output -V reverse algorithm only
-X print uppercase hexadecimal -y low bytes first in files
-z raw binary STRINGs
Mode switches:
-c calculate CRCs -d dump algorithm parameters
-D list preset algorithms -e echo (and reformat) input
-s search for algorithm -v calculate reversed CRCs
-g search for alg given hex+crc

Common Use Examples:
reveng -g 01020304e3
Searches for a known/common crc preset that computes the crc
on the end of the given hex string
reveng -w 8 -s 01020304e3 010204039d
Searches for any possible 8 bit width crc calc that computes
the crc on the end of the given hex string(s)
reveng -m CRC-8 -c 01020304
Calculates the crc-8 of the given hex string
reveng -D
Outputs a list of all known/common crc models with their
preset values
