cryptwood 0.1.4

A tool for encrypting sensitive data

cryptwood

Encryption tools for protecting private data

install

installed using pip：

python3 -m pip install cryptwood

overview

Through this tool, a python object can be quickly serialized and encrypted, and then stored in with the code directory in the project. At this point, objects that exist in the code can be deleted. In wishing to use this object When you only need to decrypt and deserialize.

In this way, sensitive information (or any information that you don't want others to see) can be avoided from appearing directly in the In the code, there is no need to appear in the project file in plain text.

Objects to be serialized and encrypted can be of any type, including custom classes. If using an object of a custom class, It is necessary to ensure that the class exists when decrypting.

This tool uses the AES256 algorithm to encrypt data symmetrically. During the encryption process, the secret key and initial vector are randomly generated. These files will be stored in~/.cryptUserDataKey.

scenes

 Use this tool to encrypt your information when you need to present projects or hand in assignments to classmates, teachers, etc. (or just for security). Like encrypting your databaseusername,passwd,host。

 Use this tool to encrypt a key object when you need to show a project to a client, Make this project only run on your computer, or only after you authorize it.

function

• cryptwood.dataCrypter.decrypt(object):
  Encrypt the object object and generate an encrypted serialized file in the code directory.cryptUserData, no return.
  Generatedkeyandivfiles are stored in~/.cryptUserDatafolder. The folder name is the code that calls this function 's parent directory location + "key" or "iv".
• cryptwood.dataCrypter.decrypt():
  Decrypts .cryptUserData and deserializes, returning an object.

TODO

• Provide a method to save key and iv in remote server using ssh for higher security, and the author Provide users with real-time code authorization to protect author rights.
• Provides a method to encrypt multiple classes at the same time
• Provides a method to store key and iv in the database for greater security, and the author Provide users with real-time code authorization to protect author rights.
