deriveKey(inputKeyMaterial:salt:outputByteCount:)
Derives a symmetric encryption key from a main key or passcode using HKDF key derivation with salt that you specify.
Declaration
static func deriveKey<Salt>(inputKeyMaterial: SymmetricKey, salt: Salt, outputByteCount: Int) -> SymmetricKey where Salt : DataProtocolParameters
- inputKeyMaterial:
The main key or passcode the derivation function uses to derive a key.
- salt:
The salt to use for key derivation.
- outputByteCount:
The length in bytes of the resulting symmetric key.
Return Value
The derived symmetric key.
