crypto_Aead_Status_E Crypto_Aead_AesGcm_Cipher(
st_Crypto_Aead_AesGcm_ctx *ptr_aesGcmCtx_st,
uint8_t *ptr_inputData,
uint32_t dataLen,
uint8_t *ptr_outData);Description
This API handles AES-GCM encryption or decryption tasks. Before using it, initialize the context by invoking the Crypto_Aead_AesGcm_Init function. If additional associated data (AAD) is needed, use Crypto_Aead_AesGcm_AddAadData. Finally, if an authentication tag is necessary, call Crypto_Aead_AesGcm_Final as the last step.
