MD5GetTag
Computes the current MD5 digest value of the processed part of the message (deprecated).
Syntax
IppStatus ippsMD5GetTag(Ipp8u* pTag, Ipp32u tagLen, const IppsMD5State* pCtx);
Include Files
ippcp.h
Parameters
pTag |
Pointer to the authentication tag. |
tagLen |
Length of the tag (in bytes). |
pCtx |
Pointer to the IppsMD5State context. |
Description
The function computes the message digest based on the current context as specified in FIPS PUB 180-2 and RFC 1321. A call to this function retains the possibility to update the digest.
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 tagLen < 1 or tagLen exceeds the maximal length of a particular digest. |
ippStsContextMatchErr |
Indicates an error condition if the context parameter does not match the operation. |
