SHA384MessageDigest

Computes SHA-384 digest value of the input message.

Syntax

IppStatus ippsSHA384MessageDigest(const Ipp8u *
pMsg
, int
len
, Ipp8u *
pMD
);
Include Files
ippcp.h
Parameters
pMsg
Pointer to the input message.
len
Message length in octets.
pMD
Pointer to the resultant digest.
Description
The function uses the selected hash algorithm to compute the digest value of the entire (non-streaming) input message.
Return Values
ippStsNoErr
Indicates no error. Any other value indicates an error or warning.
ippStsNullPtrErr
Indicates an error condition if any of the specified pointers is
NULL
.
ippStsLengthErr
Indicates an error condition if the input data stream length is less than zero.

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors.
