◆ Sha384Duplicate()

BOOLEAN EFIAPI Sha384Duplicate	(	IN CONST VOID *	Sha384Context,
		OUT VOID *	NewSha384Context
	)

Makes a copy of an existing SHA-384 context.

If Sha384Context is NULL, then return FALSE. If NewSha384Context is NULL, then return FALSE. If this interface is not supported, then return FALSE.

Parameters

[in]	Sha384Context	Pointer to SHA-384 context being copied.
[out]	NewSha384Context	Pointer to new SHA-384 context.

Return values

TRUE	SHA-384 context copy succeeded.
FALSE	SHA-384 context copy failed.
FALSE	This interface is not supported.

Definition at line 78 of file CryptSha512.c.

◆ Sha384Final()

BOOLEAN EFIAPI Sha384Final	(	IN OUT VOID *	Sha384Context,
		OUT UINT8 *	HashValue
	)

Completes computation of the SHA-384 digest value.

This function completes SHA-384 hash computation and retrieves the digest value into the specified memory. After this function has been called, the SHA-384 context cannot be used again. SHA-384 context should be already correctly initialized by Sha384Init(), and should not be finalized by Sha384Final(). Behavior with invalid SHA-384 context is undefined.

If Sha384Context is NULL, then return FALSE. If HashValue is NULL, then return FALSE.

Parameters

[in,out]	Sha384Context	Pointer to the SHA-384 context.
[out]	HashValue	Pointer to a buffer that receives the SHA-384 digest value (48 bytes).

Return values

TRUE	SHA-384 digest computation succeeded.
FALSE	SHA-384 digest computation failed.

Definition at line 158 of file CryptSha512.c.

◆ Sha384GetContextSize()

UINTN EFIAPI Sha384GetContextSize ( VOID )

Retrieves the size, in bytes, of the context buffer required for SHA-384 hash operations.

Returns: The size, in bytes, of the context buffer required for SHA-384 hash operations.

Definition at line 20 of file CryptSha512.c.

◆ Sha384HashAll()

BOOLEAN EFIAPI Sha384HashAll	(	IN CONST VOID *	Data,
		IN UINTN	DataSize,
		OUT UINT8 *	HashValue
	)

Computes the SHA-384 message digest of a input data buffer.

This function performs the SHA-384 message digest of a given data buffer, and places the digest value into the specified memory.

If this interface is not supported, then return FALSE.

Parameters

[in]	Data	Pointer to the buffer containing the data to be hashed.
[in]	DataSize	Size of Data buffer in bytes.
[out]	HashValue	Pointer to a buffer that receives the SHA-384 digest value (48 bytes).

Return values

TRUE	SHA-384 digest computation succeeded.
FALSE	SHA-384 digest computation failed.
FALSE	This interface is not supported.

Definition at line 198 of file CryptSha512.c.

◆ Sha384Init()

BOOLEAN EFIAPI Sha384Init ( OUT VOID * Sha384Context )

Initializes user-supplied memory pointed by Sha384Context as SHA-384 hash context for subsequent use.

If Sha384Context is NULL, then return FALSE.

Parameters

[out] Sha384Context Pointer to SHA-384 context being initialized.

Return values

TRUE	SHA-384 context initialization succeeded.
FALSE	SHA-384 context initialization failed.

Definition at line 41 of file CryptSha512.c.

◆ Sha384Update()

BOOLEAN EFIAPI Sha384Update	(	IN OUT VOID *	Sha384Context,
		IN CONST VOID *	Data,
		IN UINTN	DataSize
	)

Digests the input data and updates SHA-384 context.

This function performs SHA-384 digest on a data buffer of the specified size. It can be called multiple times to compute the digest of long or discontinuous data streams. SHA-384 context should be already correctly initialized by Sha384Init(), and should not be finalized by Sha384Final(). Behavior with invalid context is undefined.

If Sha384Context is NULL, then return FALSE.

Parameters

[in,out]	Sha384Context	Pointer to the SHA-384 context.
[in]	Data	Pointer to the buffer containing the data to be hashed.
[in]	DataSize	Size of Data buffer in bytes.

Return values

TRUE	SHA-384 data digest succeeded.
FALSE	SHA-384 data digest failed.

Definition at line 112 of file CryptSha512.c.

◆ Sha512Duplicate()

BOOLEAN EFIAPI Sha512Duplicate	(	IN CONST VOID *	Sha512Context,
		OUT VOID *	NewSha512Context
	)

Makes a copy of an existing SHA-512 context.

If Sha512Context is NULL, then return FALSE. If NewSha512Context is NULL, then return FALSE. If this interface is not supported, then return FALSE.

Parameters

[in]	Sha512Context	Pointer to SHA-512 context being copied.
