Field Documentation
uint32_t CRYP_InitTypeDef::DataType
32-bit data, 16-bit data, 8-bit data or 1-bit string. This parameter can be a value of
CRYP_Data_Type
uint32_t CRYP_InitTypeDef::KeySize
Used only in AES mode only : 128, 192 or 256 bit key length. This parameter can be a
value of CRYP_Key_Size
uint8_t* CRYP_InitTypeDef::pKey
The key used for encryption/decryption
uint8_t* CRYP_InitTypeDef::pInitVect
The initialization vector used also as initialization counter in CTR mode
uint8_t CRYP_InitTypeDef::IVSize
The size of initialization vector. This parameter (called nonce size in CCM) is used
only in AES-128/192/256 encryption/decryption CCM mode
uint8_t CRYP_InitTypeDef::TagSize
The size of returned authentication TAG. This parameter is used only in AES-
128/192/256 encryption/decryption CCM mode
uint8_t* CRYP_InitTypeDef::Header
The header used in GCM and CCM modes
uint32_t CRYP_InitTypeDef::HeaderSize
The size of header buffer in bytes
uint8_t* CRYP_InitTypeDef::pScratch
Scratch buffer used to append the header. It's size must be equal to header size + 21
bytes. This parameter is used only in AES-128/192/256 encryption/decryption CCM
mode
