RSA_MB_Decrypt
Performs the RSA multi-buffer decryption operation.
Syntax
IppStatus ippsRSA_MB_Decrypt(const IppsBigNumState*pCtxts[8], IppsBigNumState*pPtxts[8], const IppsRSAPrivateKeyState*pKeys[8], IppStatusstatuses[8], Ipp8u*pBuffer);
Include Files
ippcp.h
Parameters
pPtxts[8] |
Pointer to the IppsBigNumState context of the plaintext for each decryption operation. |
pCtxts[8] |
Pointer to the IppsBigNumState context of the ciphertext for each decryption operation. |
pKeys[8] |
Pointer to the IppsRSAPublicKeyState context for each decryption operation. |
statuses |
Pointer to the IppStatus array that contains statuses for each decryption operation. |
pScratchBuffer |
Pointer to the temporary buffer of size not less than returned by the RSA_MB_GetBufferSizePrivateKey function. |
Description
The function performs the RSA multi-buffer decryption operation, which is the RSA operation on a private key. The function can perform up to 8 single RSA decryption operations at once.
Each RSA decryption operation requires valid parameters that follow the ippsRSA_Decrypt syntax. After execution, the statuses array contains statuses for each single RSA decryption operation returned by ippsRSA_Decrypt.
To perform less than 8 operations, set one or more contexts in arrays to NULL. In this case, all single operations with NULL in parameters are not performed, and the function returns ippStsMbWarning .
Important
Sizes of all moduli n in all the IppsRSAPrivateKeyState contexts in the pKeys array must be equal. Types of RSA private keys must be the same.Return Values
ippStsNoErr |
Indicates no error. All single operations are executed without errors. |
Any other value indicates an error or warning. |
ippStsNullPtrErr |
Indicates an error condition if any of the specified pointers is |
NULL. |
ippStsSizeErr |
Indicates an error condition if the size of modulus n in one |
context is not equal to the size of the modulus n in other contexts. |
ippStsBadArgErr |
Indicates an error condition if types of RSA private keys are not |
the same. |
ippStsMbWarning |
Indicates a warning when one or more performed operations are |
executed with errors. For details, check the statuses array. |
