Usage

🧬 Api reference

Reading from file:

val credentials = Credentials.from(EncryptedValue.fromString("passphrase"))
val database = File("testfile.kdbx")
    .inputStream()
    .use { inputStream ->
        KeePassDatabase.decode(inputStream, credentials)
    }    

KeePassDatabase is represented as immutable object, in order to alter it use a set of modifier extensions.

Each time new KeePassDatabase object is returned:

val groupUuid = UUID.fromString("c997344c-952b-e02b-06a6-29510ce71a12")
val newDatabase = database
    .modifyMeta {
        copy(generator = "Lorem ipsum")
    }.modifyGroup(groupUuid) {
        copy(name = "Hello kotpass!")
    }
