DerivedKey Class Reference
DerivedKey
public class DerivedKey : KeyMaterialA key that is derived from a Password.
A derived key contains additional information, i.e., the parameters used to derive the key. In order to derive the same key from the password, the same parameters have to be used.
-
Minimum size of the derived key in bytes.
Declaration
Swift
public static let MinimumSizeInBytes: UInt32 -
Maximum size of the derived key in bytes.
Declaration
Swift
public static let MaximumSizeInBytes: UInt32 -
Size of the public parameters, serialized to a byte array.
Declaration
Swift
public static let SizeOfPublicParametersInBytes: UInt32 -
The salt used for deriving the key.
Declaration
Swift
let salt: Salt -
The complexity limit used for deriving the key.
Declaration
Swift
let complexityLimit: ComplexityLimit -
The memory limit used for deriving the key.
Declaration
Swift
let memoryLimit: MemoryLimit -
A byte array containing all the parameters required to derive the same key for the given password.
Declaration
Swift
public var publicParameters: Bytes { get } -
Extract the public parameters from a byte array. The size of the byte array has to be at least
SizeOfPublicParametersInBytes. The public parameters are extracted from the beginning of the byte array.Declaration
Swift
public static func extractPublicParameters(bytes: Bytes) -> (Salt, ComplexityLimit, MemoryLimit)?Parameters
bytesAn array containing serialized public parameters at the beginning.
Return Value
A tuple consisting of the salt, the complexity limit, and the memory limit used for deriving the key.
nilis returned if the byte sequence cannot be deserialized.
