    Parameters

    prk

    A pseudorandom, cryptographically strong key generated from the extract(inputKeyMaterial:salt:) function.

    info

    The shared information to use for key derivation.

    outputByteCount

    The length in bytes of the resulting symmetric key.

    Returns

    The derived symmetric key.

    Generate cryptographically strong key material to use with this function by calling extract(inputKeyMaterial:salt:).
