copy2hash

Copy or rename any file(s) to a hash-secured filename via terminal


copy2hash copies or renames file(s) with regular titles to file(s) with a hash-secured title by using the terminal or in python-framework. Having unique filenames is essential for the correct indexing of databases, especially if the data come from different pipelines. Also, it is important if the filename or/and directory contains meta-information, which extends the length of the valid file lengths.

Having regular-filename pairs such as example.inputexample.output can brings very fast confusion and makes analysis of data very confusing. The secured hash algorithms (SHA) [1-5] in copy2hash provides a safe way to generate distinguishable filenames like:

example.inputexample.output7e2229daab26b247b877565505b6aaf131014f2cb64e4c4ca796fbe0dc2fadc4.input4bd077ed771af9ad97e3f2dc45583a14af014ebafb73a846f2436a168ae3eafa.output

The following SHA algorithms [1-5] are available:

  1. sha1
  2. sha224
  3. sha256
  4. sha384
  5. sha512
  6. blake2b
  7. blake2s
  8. md5
  9. sha3_224
  10. sha3_256
  11. sha3_384
  12. sha3_512
  13. shake_128 with fixed 32 character length
  14. shake_256 with fixed 32 character length

and the copied or moved processed will be automatically logged as:

  1. *.csv-file:
  2. *.json-file
  3. *.pkl-file
  4. *.txt-file
  5. *.yaml-file
  6. *.xml-file

Usage


╰─ copy2hash * -h
usage: copy2hash [-h] [-r [REPORT [REPORT ...]]] [-rn REPORT_NAME]
                 [-s [SHA [SHA ...]]] [-dir DIRECTORY] [-mv] [-fxt] [-sxt]
                 [-nfxt] [-ver] [-v]
                 [infile [infile ...]]

copy or rename any file(s) to a hash-secured filename via terminal

positional arguments:
  infile                file(s) to copy or to rename with regular filename to
                        secured hash filename

optional arguments:
  -h, --help            show this help message and exit
  -r [REPORT [REPORT ...]], --report [REPORT [REPORT ...]]
                        define one or a series of file format(s) for the
                        rename-report(s) to retrace the copying or rename of
                        the file(s). The availabel file formats are:'csv',
                        'json', 'pkl', 'txt', 'yaml', 'xml', or own file-
                        extension as ASCII; default is 'json'
  -rn REPORT_NAME, --report_name REPORT_NAME
                        define the report name for the copied or move file(s);
                        default is 'copy_report'
  -s [SHA [SHA ...]], --sha [SHA [SHA ...]]
                        define one or a series of secure hash algorithms (sha)
                        for copying or rename of the file(s). The availabel
                        secure hash algorithms (sha) are: 'sha1', 'sha224',
                        'sha256', 'sha384', 'sha512', 'blake2b', 'blake2s',
                        'md5', 'sha3_224', 'sha3_256', 'sha3_384', 'sha3_512',
                        'shake_128', 'shake_256'; default 'sha256'. The
                        'shake_128' and 'shake_256' are defined for 32
                        character length.
  -dir DIRECTORY, --directory DIRECTORY
                        replace the standard directory ('./') by a specific
                        directory ('./path'). If the specific directory not
                        exist, the directory will be created. This can
                        required sudo rights.
  -mv, --move           moving the file(s) instead of copying the files with
                        regular filename to secure hash filename
  -fxt, --file_extension
                        replaced the given file-extension by the abbreviations
                        of the used secure hash algorithms (sha)
  -sxt, --file_suffix   removed the given file-extension and add a suffix in
                        front of the file based on the abbreviations of the
                        used secure hash algorithms (sha). It is seperated by
                        colon like 'sha256-e3b0c44298fc1c149afbf4c8996fb92427a
                        e41e4649b934ca495991b7852b855'
  -nfxt, --no_file_extension
                        removed the any file-extension and just copy or move
                        the file(s) as sha renamed file(s)
  -ver, --verbose       enable the verbose mode
  -v, --version         displays the current version of cop2hash

Other Examples


For keeping the regular file-extension, use:

copy2hash * -r json csv yaml
