4  * \brief PSA cryptography module: invasive interfaces for test only.
5  *
6  * The interfaces in this file are intended for testing purposes only.
7  * They MUST NOT be made available to clients over IPC in integrations
8  * with isolation, and they SHOULD NOT be made available in library
9  * integrations except when building the library for testing.

41 /** \brief Configure entropy sources.
42  *
43  * This function may only be called before a call to psa_crypto_init(),
44  * or after a call to mbedtls_psa_crypto_free() and before any
45  * subsequent call to psa_crypto_init().
46  *
47  * This function is only intended for test purposes. The functionality
48  * it provides is also useful for system integrators, but
49  * system integrators should configure entropy drivers instead of
50  * breaking through to the Mbed TLS API.
51  *
52  * \param entropy_init Function to initialize the entropy context
53  * and set up the desired entropy sources.
54  * It is called by psa_crypto_init().
55  * By default this is mbedtls_entropy_init().
56  * This function cannot report failures directly.
57  * To indicate a failure, set the entropy context
58  * to a state where mbedtls_entropy_func() will
59  * return an error.
60  * \param entropy_free Function to free the entropy context
61  * and associated resources.
62  * It is called by mbedtls_psa_crypto_free().
63  * By default this is mbedtls_entropy_free().
64  *
65  * \retval #PSA_SUCCESS
66  * Success.
67  * \retval #PSA_ERROR_NOT_PERMITTED
68  * The caller does not have the permission to configure
69  * entropy sources.
70  * \retval #PSA_ERROR_BAD_STATE
71  * The library has already been initialized.
