Node.js wrapper for the ssdeep fuzzy hashing library.

You will need libfuzzy installed. All major Linux distributions have it available as a package:

sudo apt-get install libfuzzy-dev

You can also install it from sources.

Then, install the Node.js wrapper:

npm install ssdeep

To compute a fuzzy hash:

var hash = ssdeep.hash('text to hash');

To compute the fuzzy hash of a file:

var hash = ssdeep.hash_from_file('file_to_hash.txt');

To compare two fuzzy hashes:

var score = ssdeep.compare(hash1, hash2);
