Function decrypt_data

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

Decrypts data that was encrypted using Windows DPAPI

Arguments

• data - The encrypted data to decrypt
• scope - The encryption scope that was used to encrypt the data

Returns

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

Errors

Returns an error if:

• The Windows API call fails
• The data is corrupted
• The current context does not match the encryption scope (e.g., wrong user or machine)
• The current user doesn’t have permission to decrypt the data
• The data was encrypted on a different machine

Examples

use windows_dpapi::{encrypt_data, decrypt_data, Scope};

fn main() -> anyhow::Result<()> {
    // First encrypt some data
    let secret = b"my secret data";
    let encrypted = encrypt_data(secret, Scope::User)?;
     
    // Then decrypt it
    let decrypted = decrypt_data(&encrypted, Scope::User)?;
    assert_eq!(secret, decrypted.as_slice());
    Ok(())
