HASHDIG-HARVEST(1) HashDig Documentation HASHDIG-HARVEST(1) NAME hashdig-harvest.pl - Harvest hashes from a one or more input files SYNOPSIS hashdig-harvest.pl [-a hash-type] [-c {K|U}] [-d delimiter] [-h hash-field] [-q] [-S sort-buffer-size] [-s sort-utility] [-T sort-temp-dir] -t file-type -o {file|-} file [file ...] DESCRIPTION This utility extracts hashes of the specified hash-type from one or more input files having the specified file-type, tags them as known or unknown (see -c), and writes them to an output file (see -o) as a sorted list of hash/category pairs. The resulting output file (a.k.a. hashdig or hd file) will have the following format: hash|category OPTIONS -a hash-type Specifies the type of hashes that are to be harvested. Currently, the following hash types (or algorithms) are supported: 'MD5', 'SHA1', and 'SHA256'. The default hash type is that specified by the HASH_TYPE en- vironment variable or 'MD5' if HASH_TYPE is not set. The value for this option is not case sensitive. -c category Specifies the category that is to be assigned to each hash. Currently, the following categories are supported: known (indicated by a 'K') and unknown (indicated by a 'U'). The value for this option is not case sensitive, and the default category is unknown (i.e., 'U'). -d delimiter Specifies the input field delimiter. This option is ignored unless used in conjunction with the 'GENERIC' data type. Valid delimiters in- clude the following characters: tab '\t', space ' ', comma ',', semi-colon ';', and pipe '|'. The default delimiter is a pipe. Note that parse errors are likely to occur if the specified delimiter ap- pears in any of the field values. -h hash-field Specifies the name of the field that contains the hash value. This op- tion is ignored unless used in conjunction with the 'GENERIC' data type. The default value for this option is 'hash'. -o {file|-} Specifies the name of the output file. A value of '-' will cause the program to write to stdout. -q Don't report errors (i.e., be quiet) while processing files. -S sort-buffer-size Specifies the buffer size the sort utility should use for its main mem- ory buffer. This option is not passed to the sort utility unless spec- ified as a command line argument. Refer to the sort(1) man page for details regarding this argument and its syntax. -s sort-utility Specifies the name of an alternate sort utility. If this argument is specified as a relative path, the current PATH will be used to locate the executable. Note that this script was designed to work with GNU sort(1). Therefore, any alternate sort utility specified must support the "-o", "-S", "-T" and "-u" options. -T sort-temp-dir Specifies the directory the sort utility should use as a temporary work area. The default directory is that specified by the TMPDIR environ- ment variable or /tmp if that variable is not set. -t file-type Specifies the type of input file that will be processed. Note that all files processed in a single invocation must be of the same type. Cur- rently, the following types are supported: 'FTIMES', 'FTK', 'GENERIC', 'HK' or 'HASHKEEPER', 'KG' or 'KNOWNGOODS', 'MD5', 'MD5DEEP', 'MD5SUM', 'NSRL1', 'NSRL2', 'OPENSSL', 'PLAIN', 'RPM', 'SHA1', 'SHA1DEEP', 'SHA1SUM', 'SHA256', 'SHA256DEEP', and 'SHA256SUM'. The value for this option is not case sensitive.
