Typedef Documentation

HASH_ALL_METHOD

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

Computes the message digest of a input data buffer.

This function performs 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 digest value.

Return values

TRUE	The digest computation succeeded.
FALSE	The digest computation failed.

Definition at line 51 of file FvReportPei.h.

HASH_FINAL_METHOD

typedef BOOLEAN(EFIAPI * HASH_FINAL_METHOD) (IN OUT VOID *HashContext, OUT UINT8 *HashValue)

Completes computation of the hash digest value.

Parameters

[in,out]	HashContext	Pointer to the hash context.
[out]	HashValue	Pointer to a buffer that receives the hash digest value.

Return values

TRUE	Hash digest computation succeeded.
FALSE	Hash digest computation failed.
FALSE	This interface is not supported.

Definition at line 107 of file FvReportPei.h.

HASH_INIT_METHOD

typedef BOOLEAN(EFIAPI * HASH_INIT_METHOD) (OUT VOID *HashContext)

Initializes user-supplied memory as hash context for subsequent use.

Parameters

[out]

HashContext

Pointer to hash context being initialized.

Return values

TRUE	Hash context initialization succeeded.
FALSE	Hash context initialization failed.
FALSE	This interface is not supported.

Definition at line 69 of file FvReportPei.h.

HASH_UPDATE_METHOD

typedef BOOLEAN(EFIAPI * HASH_UPDATE_METHOD) (IN OUT VOID *HashContext, IN CONST VOID *Data, IN UINTN DataSize)

Digests the input data and updates hash context.

Parameters

[in,out]	HashContext	Pointer to the hash context.
[in]	Data	Pointer to the buffer containing the data to be hashed.
[in]	DataSize	Size of Data buffer in bytes.

Return values

TRUE	Hash data digest succeeded.
FALSE	Hash data digest failed.
FALSE	This interface is not supported.
