Features

• runs in browser or node.js
• no native addons
• average file open time is 200ms
• total ≈150kB with dependencies
• full support of Kdbx features
• protected values are stored in memory XOR'ed

Browser support

• modern browsers: IE10+, Firefox, Chrome, Safari 7+, Opera
• node.js

Usage

Loading

var credentials = new kdbxweb.Credentials(kdbxweb.ProtectedValue.fromString('demo'), keyFileArrayBuffer);
kdbxweb.Kdbx.load(data, credentials, function(db) {  });

Saving

db.save(function(dataAsArrayBuffer) {  });
db.saveXml(function(xmlAsString) {  });

File info

Header object fields
Meta object fields

db.header
db.meta

Changing credentials

var db = kdbxweb.Kdbx.load(data, credentials);
db.credentials.setPassword(kdbxweb.ProtectedValue.fromString('newPass'));
var randomKeyFile = kdbxweb.Credentials.createRandomKeyFile();
db.credentials.setKeyFile(randomKeyFile);
db.save();

Creation

var newDb = kdbxweb.Kdbx.create(credentials, 'My new db');
var group = newDb.createGroup(newDb.getDefaultGroup(), 'subgroup');
var entry = newDb.createEntry(group);

Groups

Group object fields

var defaultGroup = db.getDefaultGroup();
var anotherGroup = db.getGroup(uuid);
var deepGroup = defaultGroup.groups[1].groups[2];

Group creation

var group = db.createGroup(db.getDefaultGroup(), 'New group');
var anotherGroup = db.createGroup(group, 'Subgroup');

Group deletion

db.remove(group, parentGroup);

Group move

db.remove(group, parentGroup, toGroup);

Recycle Bin

var recycleBin = db.getGroup(db.meta.recycleBinUuid);
if (!recycleBin) {
    db.createRecycleBin();
}

Entries

Entry object fields
Entry.times fields

var entry = db.getDefaultGroup().entries[0];
entry.fields.AccountNumber = '1234 5678';
entry.fields.Pin = kdbxweb.ProtectedValue.fromString('4321');

Entry creation

var entry = db.createEntry(group);

Entry modification

// push current state to history stack
entry.pushHistory();
// change something
entry.fgColor = '#ff0000';
// update entry modification and access time
entry.times.update();

Entry deletion

db.remove(entry, parentGroup);

Entry move

db.remove(entry, parentGroup, toGroup);

ProtectedValue

Used for passwords and custom fields, stored the value in memory XOR'ed

var value = new kdbxweb.ProtectedValue(xoredByted, saltBytes);
var valueFromString = kdbxweb.ProtectedValue.fromString('str');
var valueFromBinary = kdbxweb.ProtectedValue.fromBinary(data);
var textString = value.getText();
var binaryData = value.getBinary();
var includesSubString = value.includes('foo');

Errors

try {
    kdbxweb.Kdbx.load(data, credentials);
} catch (e) {
    if (e.code === kdbxweb.Consts.ErrorCodes.BadSignature) { /* ... */ }
}

Consts

Consts definition

kdbxweb.Consts.ErrorCodes // all thrown errors have code property
kdbxweb.Consts.Defaults // default db settings
kdbxweb.Consts.Icons // icons map

Random

var randomArray = kdbxweb.Random.getBytes(/* desired length */ 100);

ByteUtils

kdbxweb.ByteUtils.bytesToString(bytes);
kdbxweb.ByteUtils.stringToBytes(str);
kdbxweb.ByteUtils.bytesToBase64(bytes)
kdbxweb.ByteUtils.base64ToBytes(str);;

Contributing

Areas which need more attention for now:

• unit tests, especially for complex functions (like moving entry with binaries)
• testing in general
• better documentation
• merge files support
