Rust KeePass database file parser for KDB, KDBX3 and KDBX4, with experimental support for KDBX4 writing.


Open a database

use keepass::{
use std::fs::File;

fn main() -> Result<(), DatabaseOpenError> {
    // Open KeePass database using a password (keyfile is also supported)
    let mut file = File::open("tests/resources/test_db_with_password.kdbx")?;
    let key = DatabaseKey::new().with_password("demopass");
    let db = Database::open(&mut file, key)?;

    // Iterate over all `Group`s and `Entry`s
    for node in &db.root {
        match node {
            NodeRef::Group(g) => {
                println!("Saw group '{0}'", g.name);
            NodeRef::Entry(e) => {
                let title = e.get_title().unwrap_or("(no title)");
                let user = e.get_username().unwrap_or("(no username)");
                let pass = e.get_password().unwrap_or("(no password)");
                println!("Entry '{0}': '{1}' : '{2}'", title, user, pass);


Save a KDBX4 database (EXPERIMENTAL)

IMPORTANT: The inner XML data structure will be re-written from scratch from the internal object representation of this crate, so any field that is not parsed by the library will be lost in the written output file! Please make sure to back up your database before trying this feature.

You can enable the experimental support for saving KDBX4 databases using the save_kdbx4 feature.

use keepass::{
    db::{Database, Entry, Group, Node, NodeRef, Value},
use std::fs::File;

fn main() -> Result<(), Box<dyn std::error::Error>> {
    let mut db = Database::new(Default::default());

    db.meta.database_name = Some("Demo database".to_string());

    let mut group = Group::new("Demo group");

    let mut entry = Entry::new();
    entry.fields.insert("Title".to_string(), Value::Unprotected("Demo entry".to_string()));
    entry.fields.insert("UserName".to_string(), Value::Unprotected("jdoe".to_string()));
    entry.fields.insert("Password".to_string(), Value::Protected("hunter2".as_bytes().into()));



    #[cfg(feature = "save_kdbx4")]
        &mut File::create("demo.kdbx")?,


Use developer tools

This crate contains several command line tools that can be enabled with the utilities feature flag. See the [[bin]] sections in Cargo.toml for a complete list.

An example command line for running the kp-dump-xml command would be:

cargo run --release --features "utilities" --bin kp-dump-xml -- path/to/database.kdbx


Add the following to the dependencies section of your Cargo.toml:

keepass = "*" # TODO replace with current version

Performance Notes

Please set the RUSTFLAGS environment variable when compiling to enable CPU-specific optimizations (this greatly affects the speed of the AES key derivation):

export RUSTFLAGS='-C target-cpu=native'

For best results, also compile in Release mode.

Alternatively, you can add a .cargo/config.toml like in this project to ensure that rustflags are always set.

For AArch64 / ARMv8:

The aes optimizations are not yet enabled on stable rust. If you want a big performance boost you can build using nightly and enabling the armv8 feature of the aes crate:

# Needs at least 0.7.5 for the feature
version = "0.7.5"
features = ["armv8"]
