Installation

To install:

python3 -m pip install simd5

To upgrade add -U:

python3 -m pip install -U simd5

Usage

To create a MD5 file with the filenames and hashes:

import simd5

simd5.md5_file(folder="files", fileformat="m f", no_workers=4)

The command can take these arguments:

• folder: Which folder to run in. Will ignore subfolders.
• fileformat: What format to use when creating the MD5 file: ** m f: [MD5 hash] [filename] (space-separated) ** f m: [filename] [MD5 hash] (space-separated) ** m,f: [MD5 hash],[filename] (comma-separated) ** f,m: [filename],[MD5 hash] (comma-separated)
• no_workers: How many parallel processes to use. By default, it will use the number of cores found in the system.

To verify if the files match a reference md5 file:

from simd5 import simd5

simd5.check_md5_file(md5_file="file.md5", files="*.tif*", csv=True, no_workers=4)

The command can take these arguments:

• md5_file: The file with the hash and filenames
• files: A search pattern for which files to compare the hashes
• csv: Save the results to a results.csv file
• no_workers: How many parallel processes to use. By default, it will use the number of cores found in the system.
