How can I use this project in Python?

[MrT3acher]

Hi I've built the project using cargo build --release. Now I see librabe.so file. It contains these symbols (using nm command):

0000000000004008 b completed.8061
                 w __cxa_finalize@@GLIBC_2.2.5

I don't see any encrypt or decrypt function. Did I have a mistake in building the project? or is there another way to see the exports of this shared object (so) file.

finally I want to use this project in python language.

Let's go one by one. In general, information to use Rabe can be found here.

There are many different schemes offered by Rabe: BSW07, KP-ABE FAME, FAME, LW11, YCT14, etc. If you have installed rabe correctly, whenever you use it in a rust script you may have a cargo.toml looking like this:

[package]
name = "NAME"
version = "0.1.0"
edition = "2021"

# See more keys and their definitions at https://doc.rust-lang.org/cargo/reference/manifest.html

[dependencies]
rabe = "0.3.1"

[dev-dependencies]
criterion = "0.3"

[[bench]]
name = "SCRIPT_NAME"
harness = false

And below you have an example on how to use BSW, extracted from the documentation

use rabe::schemes::bsw::*;
use rabe::utils::policy::pest::PolicyLanguage;
let (pk, msk) = setup();
let plaintext = String::from("dance like no one's watching, encrypt like everyone is!").into_bytes();
let policy = String::from(r#""A" and "B""#);
let ct_cp: CpAbeCiphertext = encrypt(&pk, &policy, &plaintext, PolicyLanguage::HumanPolicy).unwrap();
let sk: CpAbeSecretKey = keygen(&pk, &msk, &vec!["A".to_string(), "B".to_string()]).unwrap();
assert_eq!(decrypt(&sk, &ct_cp).unwrap(), plaintext);

Regarding its use with python, I'm sorry but I do not know how to create a Python wrapper. However, you may find useful the Python ABE library, Charm.

I had implemented the CFFI and a C# wrapper library for all algorithms in rabe. If you need it to create a wrapper in Python or other languages, please check my repositories (Rabe-ffi).

Thanks! I finally used https://github.com/MrT3acher/mosaic.

I'm using Maturin to call RABE from Python successfully.
