Function Documentation

any_key desfire::kdf_an10922(crypto &crypto, mlab::bin_data &diversify_input, std::uint8_t key_version)

Specialization of the AN10922 KDF function which returns a packages any_key object.

This overload can operate on any crypto subclass, even those that do not derive from crypto_des_base, crypto_2k3des_base, crypto_3k3des_base, crypto_aes_base. The cipher is obtained from crypto::cipher_type. New CMAC keys are always derived when running this overload.

Parameters:

• crypto – Cryptographic object on which the CMAC operation will be run.

• diversify_input – Diversification input. At most 2 * BlockSize - 1 bytes wil be used. It will be modified by the operation.

• key_version – Key version to set in the returned object.

Returns:
