PsComputeSha1Physical

Calculates a SHA-1 hash of a data block referenced by a physical address.

Syntax

PULSE_STATUS PsComputeSha1Physical(
[in] PPS_ENGINE pEngine,
[in] uint64_t Address,
[in] uint64_t cbToRead,
[out] PPS_SHA1_HASH pSha1Hash,
[out, optional] uint64_t* pcbRead
);

Parameters

PPS_ENGINE pEngine

An opaque handle to an engine created by the EngCreateEngine function.

uint64_t Address

The physical address of the data to be hashed.

uint64_t cbToRead

Specifies how many bytes should be hashed.

PPS_SHA1_HASH pSha1Hash

The buffer that stores the hash data.

uint64_t* pcbRead

Returns the number of bytes that were actually hashed.

Return value

If the function succeeds, the return value is PULSE_STATUS_SUCCESS.

If it fails, it returns one of the PULSE_STATUS values. Possible return codes include, but are not limited to, the following:

PULSE_STATUS_PARTIAL_READ 0x00000001	Only a portion of memory was read. Check the *pcbRead parameter value to determine how many bytes were read.
PULSE_STATUS_INSUFFICIENT_RESOURCES 0xC0000002	One of the memory allocations failed during initialization.
PULSE_STATUS_READ_FAILED 0xC0000003	Transport communication failed during a read operation.
PULSE_STATUS_WRITE_FAILED 0xC0000004	Transport communication failed during a write operation.
PULSE_STATUS_TIMEOUT 0xC0000007	Might happen if Transport I/O timed out. No response was received from the debuggee within the request timeout period.
PULSE_STATUS_INVALID_PARAMETER 0xC0000010	Might happen if The pEngine parameter is NULL. The pSha1Hash parameter is NULL.
PULSE_STATUS_INVALID_PACKET 0xC0000031	An invalid or unexpected packet was received in response.
PULSE_STATUS_INVALID_TRANSLATION 0xC0000021	The specified physical address is above the maximum addressable on the target platform.
PULSE_STATUS_DEVICE_CONNECTION_LOST 0xC0000308	The connection to the transport was lost. Try restarting the engine or the transport.

Remarks

Partial reads may occur when address translation is not available beyond a certain point.
