jc-sdhash 0.2.1

A Python wrapper for the SDHash binary.

jc_sdhash - SDHash Python Wrapper

This Python package provides a simple, functional wrapper for the SDHash binary, allowing you to generate and compare SDBF hashes directly from Python. Note: This package only works on Linux.

Installation

You can install jc_sdhash either from PyPI or from the source.

Option 1: Install from PyPI

pip install jc_sdhash

Usage The package provides a functional API, similar to ssdeep. Import it as jc_sdhash and use its functions directly.

Importing the Package

import jc_sdhash as sd

Usage Options Option 1: Generate an SDBF Hash and Print to Console Generate a hash for a file and print it to standard output:

import jc_sdhash as sd
# Generate the SDBF hash for a file
result = sd.generate("inputfile.txt")
print(result)

Option 2: Generate an SDBF Hash and Save to File Generate a hash and save it to a specified output file:

import jc_sdhash as sd
# Generate the SDBF hash and save it to "output.sdbf"
sd.generate("inputfile.txt", output_filepath="output.sdbf")

Option 3: Compare Two SDBF Hash Files Compare two SDBF files and print the similarity score:

import jc_sdhash as sd

# Compare two SDBF files
result = sd.compare("file1.sdbf", "file2.sdbf")
print(result)

Option 4: Validate an SDBF File Validate the integrity of an SDBF file:

import jc_sdhash as sd

# Validate an SDBF file
result = sd.validate("file1.sdbf")
print(result)

Function Details

generate(filepath, output_filepath=None)

Generates an SDBF hash for the given file.
If output_filepath is provided, the hash is saved there; otherwise, it’s returned as a string.

compare(file1, file2)

Compares two SDBF files and returns the similarity score as a string.

validate(sdbf_file)

Validates an SDBF file and returns the result as a string.

Requirements

• Python 3.6+
• Linux-based OS (this package only works on Linux)
• The sdhash binary (included in the package)
• Read access to input files and write access for output files (if saving hashes)

Troubleshooting

Missing Binary

If you get a FileNotFoundError, ensure the sdhash binary is in the jc_sdhash/ directory and executable:

chmod +x jc_sdhash/sdhash
