struct SodiumKeyDerivationA wrapper for key derivation.
-
The size of the master key in bytes.
Declaration

let masterKeySizeInBytes: Int -
The size of a sub key context in bytes.
Declaration
Swift
let contextSizeInBytes: Int -
The minimum size of a derived key in bytes.
Declaration
Swift
let minimumSubKeySizeInBytes: Int -
The maximum size of a derived key in bytes.
Declaration
Swift
let maximumSubKeySizeInBytes: Int -
Generate a master key.
Declaration
Swift
func keygen(_ pointer: UnsafeMutablePointer<UInt8>)Parameters
pointerThe memory region where the key will be stored.
-
Derive a sub key from a given master key.
