Function encrypt_data 

pub fn encrypt_data(
    data: &[u8],
    scope: Scope,
    entropy: Option<&[u8]>,
) -> Result<Vec<u8>>

Encrypts data using Windows DPAPI

Arguments

• data - The data to encrypt
• scope - The encryption scope (User or Machine)
• entropy - Optional additional entropy data to strengthen encryption

Returns

Returns a Result containing the encrypted data as a Vec<u8> if successful.

Errors

Returns an error if:

• The Windows API call fails
• Memory allocation fails
• The current user doesn’t have permission to encrypt data

Examples

use windows_dpapi::{encrypt_data, Scope};

fn main() -> anyhow::Result<()> {
    let secret = b"my secret data";
    let entropy = b"my entropy";
    let encrypted = encrypt_data(secret, Scope::User, Some(entropy))?;
    Ok(())
}
