void HASH_DeInit ( void )

De-initializes the HASH peripheral registers to their default reset values.

Parameters

None

Return values

None

Definition at line 171 of file stm32f4xx_hash.c.

Here is the call graph for this function:

Here is the caller graph for this function:

void HASH_Init ( HASH_InitTypeDef * HASH_InitStruct )

Initializes the HASH peripheral according to the specified parameters in the HASH_InitStruct structure.

Note: the hash processor is reset when calling this function so that the HASH will be ready to compute the message digest of a new message. There is no need to call HASH_Reset() function.

Parameters

HASH_InitStruct pointer to a HASH_InitTypeDef structure that contains the configuration information for the HASH peripheral.

Note: The field HASH_HMACKeyType in HASH_InitTypeDef must be filled only if the algorithm mode is HMAC.

Return values

None

Definition at line 191 of file stm32f4xx_hash.c.

Here is the caller graph for this function:

void HASH_Reset ( void )

Resets the HASH processor core, so that the HASH will be ready to compute the message digest of a new message.

Note: Calling this function will clear the HASH_SR_DCIS (Digest calculation completion interrupt status) bit corresponding to HASH_IT_DCI interrupt and HASH_FLAG_DCIS flag.

Parameters

None

Return values

None

Definition at line 249 of file stm32f4xx_hash.c.

void HASH_StructInit ( HASH_InitTypeDef * HASH_InitStruct )

Fills each HASH_InitStruct member with its default value.

Parameters

HASH_InitStruct : pointer to a HASH_InitTypeDef structure which will be initialized.

Note: The default values set are : Processor mode is HASH, Algorithm selected is SHA1, Data type selected is 32b and HMAC Key Type is short key.

Return values

None
