Hashing algorithms are designed to have a high likelihood of producing a significantly different number for even small differences in input data. As such, they are useful gaining a degree of certainly about whether a particular data set has changed without having to store the whole data set.Reads data to be hashed either from a file or from STDIN. Writes the corresponding hash either to a file or to STDOUT. Supports a variety of different hashing algorithms.Defaults to using the SHA1 algorithm if the '-a' option is not specified. This means that to create an hash file of an executable file stored on removable media (such that F32 will allow it to be loaded), run: hash -i <executable_file_name> -o c:\sys\hash\<executable_file_name>==option bool v verboseVerbose output.==option filename i inputThe name of the file whose data is to be hashed. If not specified, data is read from STDIN.==option filename o outputThe name of the file to write the hash to. If not specified, the hash is ASCII / hex dumped to STDOUT.==option enum a algorithm==enum-value SHA1==enum-value MD2==enum-value MD4==enum-value MD5==enum-value SHA224==enum-value SHA256==enum-value SHA384==enum-value SHA512==copyrightCopyright (c) 2009-2010 Accenture.
