Crate cargo_pwhide

cargo-pwhide provides tooling to hide passwords

This doesn’t provide any security

It consists of a cargo subcommand to encrypt passwords and a simple macro for decrypting

Encryption

install the cargo subcommand with:
cargo install cargo-pwhide

Then go to the root of your project where the Cargo.toml is
and encrypt a password

cargo pwhide encrypt MySecretPassword

This will deliver an encrypted data for example:

QDc2rswTJRHrFEgT2Ech77xuScNGfGGKFIJq6MJcI1lKg1hfaowsg5

Use this in configuration files on in the command code

Decryption in the program

Add to your Config.toml

cargo-pwhide = {version="*", feature=["lib"], default-features = false}**

This reduces the number of dependencies and is great for compile time :)

For decryption just use the provided macro

use cargo_pwhide::pwdecrypt;    
let cleartext:Result<String,anyhow::Error>=pwdecrypt!("QDc2rswTJRHrFEgT2Ech77xuScNGfGGKFIJq6MJcI1lKg1hfaowsg5");  

and automatically decrpytion is done

how does it work?

The tool is using the package name as secret The password is encrypted using ChaCha20Poly1305 and a random nounce

This doesn’t provide any security but is better compared to storing plain text passwords in version control

Macros

• pwdecrypt
  The macro is used for easy decrpytion of password

Functions

• pwdecrypt
  This is used to decrpyt the password encrypted with subcommand tools cargo pwhide encrypt
• pwencrypt
  This is used to encrpyt a password function used by subcommand tools cargo pwhide encrypt
