Project description
hashdir
A command line tool to calculate hash of directory trees using various hash algorithms.
installation
To install run the following command in your terminal:
pip3 install hashdir
usage
usage: hashdir [-h] [-a {md5,sha1,imohash}] [--log-level {error,info,debug}]
[directory]
hashdir
positional arguments:
directory
optional arguments:
-h, --help show this help message and exit
-a {md5,sha1,imohash}, --algorithm {md5,sha1,imohash}
warning: imohash is a constant-time hashing library,
and while being fast for large files, it produces
approximate results.
--log-level {error,info,debug}
algorithm
Hashdir performs the following steps;
- Walk the directory tree and find all file paths.
- Sort file paths to get a consistent hash for every system.
- Compute the hash value for each file separately using the algorithm selected by the -a option (Or md5 as default).
- Create a "hash string" using the results. Hash string is a string value which consists of a file path and its hash separated by a space character on each line. Print the hash string.
- Compute the md5 hash value of the hash string and return as the result.
