msoffice_decrypt

Don't use this. Use nolze's project instead.

msoffice_decrypt is a Python tool and library for decrypting encrypted MS Office files with a password. This work is based on https://github.com/nolze/msoffcrypto-tool. I created this project to solves a specific use case for myself.

Installation

Stable release

pip3 install -U msoffice_decrypt

From GitHub

pip3 install -U git+https://github.com/unixfreak0037/msoffice_decrypt

Examples

(command line) Decrypt a file with a password.

msoffice_decrypt -p 7779 Scan_ciwilson.doc Scan_ciwilson_unencrypted.doc

decrypted Scan_ciwilson.doc into Scan_ciwilson_unencrypted.doc

(command line) Decrypt a file trying everything that might be a password in this other file.

msoffice_decrypt -i sample.txt Scan_ciwilson.doc Scan_ciwilson_unencrypted.doc

found password: 7779
decrypted Scan_ciwilson.doc into Scan_ciwilson_unencrypted.doc

(library)

from msoffice_decrypt import MSOfficeDecryptor
decryptor = MSOfficeDecryptor(input_file_path, output_file_path)
if decryptor.is_decryptable:
    # generate a list of passwords that might be right
    # here we assume sample.txt is a text file that contains the password somewhere
    with open('sample.txt', 'r') as fp:
        word_list = decryptor.find_password(fp)

    # see if any of these passwords are correct
    password = decryptor.guess(word_list)

    if password:
        decryptor.decrypt(password)
