psa_drv_se_cipher_t struct
A struct containing all of the function pointers needed to implement cipher operations using secure elements. PSA Crypto API implementations should populate instances of the table as appropriate upon startup or at build time. If one of the functions is not implemented (such as `psa_drv_se_cipher_ecb_t`), it should be set to NULL.
Syntax
typedef struct
{
size_t MBEDTLS_PRIVATE(context_size);
psa_drv_se_cipher_setup_t MBEDTLS_PRIVATE(p_setup);
psa_drv_se_cipher_set_iv_t MBEDTLS_PRIVATE(p_set_iv);
psa_drv_se_cipher_update_t MBEDTLS_PRIVATE(p_update);
psa_drv_se_cipher_finish_t MBEDTLS_PRIVATE(p_finish);
psa_drv_se_cipher_abort_t MBEDTLS_PRIVATE(p_abort);
psa_drv_se_cipher_ecb_t MBEDTLS_PRIVATE(p_ecb);
} psa_drv_se_cipher_t;

Description
The size in bytes of the hardware-specific secure element cipher context structure.
Function that performs a cipher setup operation.
Function that sets a cipher IV (if necessary).
Function that performs a cipher update operation.
Function that completes a cipher operation.
Function that aborts a cipher operation.
Function that performs ECB mode for a cipher operation (Danger: ECB mode should not be used directly by clients of the PSA Crypto Client API).
