Encryption and Decryption

[StefanGreve]

Preamble

For privacy and security reasons, it makes sense to encrypt files prior to uploading them to a third-party server. anonpy should implement the facilities that make it possible to do this with ease.

Requirements

This project should support both symmetric and asymmetric encryption. For starters, implement the following functions in the anonpy.security namespace:

• Symmetric.encrypt()
• Symmetric.decrypt()
• Asymmetric.encrypt()
• Asymmetric.decrypt()

The precise function signature of these functions above are not set in stone.
Stretch goal: implement the following functions in a anonpy.algorithm namespace:

• Checksum.compute_md5(path: Union[str, Path]) -> str
• Checksum.compute_sha1(path: Union[str, Path]) -> str
• Checksum.compute_sha256(path: Union[str, Path]) -> str

Remarks

• use the pyca/cryptography library
• the CLI shouldn't need to be updated yet but at a later time
• add unit tests

Planning Status

Scheduled for milestone 1.0.0.
