hash-checker

A utility to check cryptographic hashes of files

Release Notes

v2.0

Usage:

hash-checker [/w] [/m] [/s] [/S] file1 [file2] [file3]...

hash-checker [/write-to-file] [/md5] [/sha1] [/sha256] file1 [file2] [file3]...

hash-checker [-w] [-m] [-s] [-S] file1 [file2] [file3]...

hash-checker [--write-to-file] [--md5] [--sha1] [--sha256] file1 [file2] [file3]...

• w or write-to-file - Specifies that the output has to be dumped to a file rather than console
• m or md5 - Generates the MD5 hash
• s or sha1- Generates the SHA1 hash
• S or sha256- Generates the SHA256 hash
• file - Specifies the input files whose hashes have to be calculated (at least one file must be specified)

NOTES:

• The arguments can be used together in any order (but must be specified before the input files)
• In the absence of any of md5, sha1 or sha256, the program defaults to generating all the three hashes

Output:

• If you specified the /w option then the requested hashes will be written to a file with the same name and path as the last input file that you specified. hash-checker /w D:\file1 D:\file2 will cause the output to be written to D:\file2.checksum
• When none of the arguments specifying the hash technique are passed the program defaults to generating all the three hashes
• If the input file does not exist, a message is displayed stating the same
• Upon any kind of unexpected input a message showing the expected input is displayed and the program terminates

Known issues:

• If the output file already exists, then the program will simply append its output to the end of the file.
