create_crypto_box

Creates a Crypto Box instance.

Crypto Box is a root crypto object, that encapsulates some secret (seed phrase usually) in encrypted form and acts as a factory for all crypto primitives used in SDK: keys for signing and encryption, derived from this secret.

Crypto Box encrypts original Seed Phrase with salt and password that is retrieved from password_provider callback, implemented on Application side.

When used, decrypted secret shows up in core library's memory for a very short period of time and then is immediately overwritten with zeroes.

type ParamsOfCreateCryptoBox = {
    secret_encryption_salt: string,
    secret: CryptoBoxSecret
}

type RegisteredCryptoBox = {
    handle: CryptoBoxHandle
}

function create_crypto_box(
    params: ParamsOfCreateCryptoBox,
    obj: AppPasswordProvider,
): Promise<RegisteredCryptoBox>;

function create_crypto_box_sync(
    params: ParamsOfCreateCryptoBox,
): RegisteredCryptoBox;

NOTE: Sync version is available only for lib-node binding.

Parameters

secret_encryption_salt: string – Salt used for secret encryption. For example, a mobile device can use device ID as salt.
secret: CryptoBoxSecret – Cryptobox secret
obj: AppPasswordProvider – Interface that provides a callback that returns an encrypted password, used for cryptobox secret encryption

Result

handle: CryptoBoxHandle

remove_crypto_box

Removes Crypto Box. Clears all secret data.

type RegisteredCryptoBox = {
    handle: CryptoBoxHandle
}

function remove_crypto_box(
    params: RegisteredCryptoBox,

function remove_crypto_box_sync(
    params: RegisteredCryptoBox,
): void;
