Features

• Master Key can be of arbitrary length
• Designed with Migration in mind
• Recovery Key by design
• Different Serialization types

Installation

CocoaPods

pod 'Crypto', :git => 'https://github.com/passlock/Crypto.git'
pod 'Vault1', :git => 'https://github.com/passlock/Vault.git'

Usage

Create

let password: String = ...
let databaseEncryptionKey: Bytes = ...


let created = Vault1.create(password: password, master: databaseEncryptionKey, serializer: ProtobufSerializer.self)

Open

let openedWithPassword = try Vault1.open(password: password, serialized: created.serialized, serializer: ProtobufSerializer.self)
let openedWithIntermediate = try Vault1.open(intermediate: created.vault.intermediate, serialized: created.serialized, serializer: ProtobufSerializer.self)

Change

let changedWithPassword = try Vault1.change(old: password, new: "newPassword", serialized: created.serialized, serializer: ProtobufSerializer.self)
let changedWithIntermediate = try Vault1.change(intermediate: created.vault.intermediate, new: "newPassword", serialized: created.serialized, serializer: ProtobufSerializer.self)

Master Key

Master Key - is an arbitrary length piece of Data, note that depending on your case it may be needed to pad that data.

Migration / Upgrade

Designed with Migration in mind, current branch is Vault1 intentionaly as for now it use 20 CPU, and 32MB of RAM. The idea is, if we need to modify CPU or RAM, we'll create another branch with this parameters.

Recovery Key / Intermediate Key

Intermediate Key is used as a Spare Key, you are responsable to keep it safe. The idea is to not share with someone else your Master Password but some random characters. If you don't want to use Recovery Key you can safely ignore it.

Serialization

• Protobuf, default
• JSON
• Support custom serialization
