CRYP_ConfigTypeDef struct

32-bit data, 16-bit data, 8-bit data or 1-bit string. This parameter can be a value of CRYP_Data_Type.

Used only in AES mode : 128, 192 or 256 bit key length in CRYP1. 128 or 256 bit key length in TinyAES This parameter can be a value of CRYP_Key_Size.

The key used for encryption/decryption.

The initialization vector used also as initialization counter in CTR mode.

DES/ TDES Algorithm ECB/CBC AES Algorithm ECB/CBC/CTR/GCM or CCM This parameter can be a value of CRYP_Algorithm_Mode.

used only in AES GCM and CCM Algorithm for authentication, GCM : also known as Additional Authentication Data CCM : named B1 composed of the associated data length and Associated Data.

The size of header buffer in word.

B0 is first authentication block used only in AES CCM mode.

Data With Unit, this parameter can be value of CRYP_Data_Width_Unit.

Header Width Unit, this parameter can be value of CRYP_Header_Width_Unit.

CRYP peripheral Key and IV configuration skip, to config Key and Initialization Vector only once and to skip configuration for consecutive processings. This parameter can be a value of CRYP_Configuration_Skip.
