Macro Definition Documentation

#define PSA_KEY_DERIVATION_INPUT_INFO   ((psa_key_derivation_step_t)0x0203)

An information string for key derivation.

This should be a direct input. It can also be a key of type PSA_KEY_TYPE_RAW_DATA.

Definition at line 1790 of file crypto_values.h.

#define PSA_KEY_DERIVATION_INPUT_LABEL   ((psa_key_derivation_step_t)0x0201)

A label for key derivation.

This should be a direct input. It can also be a key of type PSA_KEY_TYPE_RAW_DATA.

Definition at line 1776 of file crypto_values.h.

#define PSA_KEY_DERIVATION_INPUT_SALT   ((psa_key_derivation_step_t)0x0202)

A salt for key derivation.

This should be a direct input. It can also be a key of type PSA_KEY_TYPE_RAW_DATA.

Definition at line 1783 of file crypto_values.h.

#define PSA_KEY_DERIVATION_INPUT_SECRET   ((psa_key_derivation_step_t)0x0101)

A secret input for key derivation.

This should be a key of type PSA_KEY_TYPE_DERIVE (passed to psa_key_derivation_input_key()) or the shared secret resulting from a key agreement (obtained via psa_key_derivation_key_agreement()).

The secret can also be a direct input (passed to key_derivation_input_bytes()). In this case, the derivation operation may not be used to derive keys: the operation will only allow psa_key_derivation_output_bytes(), not psa_key_derivation_output_key().

Definition at line 1769 of file crypto_values.h.

#define PSA_KEY_DERIVATION_INPUT_SEED   ((psa_key_derivation_step_t)0x0204)

A seed for key derivation.

This should be a direct input. It can also be a key of type PSA_KEY_TYPE_RAW_DATA.

Definition at line 1797 of file crypto_values.h.
