Properties

hashedUserId

val hashedUserId: <Error class: unknown class>

The hashed ID of the user that originally created this backup. This hash is calculated using Argon2, with this salt, operationsLimit and hashingMemoryLimit. This array is HASHED_USER_ID_SIZE_IN_BYTES long.

hashingMemoryLimit

val hashingMemoryLimit: Int

Memory used by the hashing algorithm. See Libsodium's Documentation. This value has to be bigger than crypto_pwhash_MEMLIMIT_MIN.

operationsLimit

val operationsLimit: <Error class: unknown class>

Represents the maximum amount of computations to perform. Raising this number will make the function require more CPU cycles to compute a key. See Libsodium's Documentation.

salt

val salt: <Error class: unknown class>

The salt used in order to create the hashedUserId and used to derivate the encryption password to read/write the encrypted archive. This array is SALT_SIZE_IN_BYTES long.
