any_key desfire::kdf_an10922(any_key const &key, cipher_provider &provider, mlab::bin_data &diversify_input)

Specialization of the AN10922 KDF function for specific key types.

These overloads can derive a new key from a given key object, by creating the appropriate cipher.

Parameters:

key – Key to diversify.
provider – Cipher provider for building the correct crypto implementation.
diversify_input – Diversification input. At most 2 * BlockSize - 1 bytes wil be used. It will be modified by the operation.

Returns:

A diversified key of the same type, with the same version.
