Consumer of the kernel crypto api, after allocating the transformation, sets this flag based on the basis of the type of key consumer has. This helps: - This helps to influence the core processing logic for the encapsulated algorithm. - This flag is set by the consumer after allocating the tfm and before calling the function crypto_xxx_setkey().
