Parameters
- pPtxts[8]
- Pointer to theIppsBigNumStatecontext of the plaintext for each decryption operation.
- pCtxts[8]
- Pointer to theIppsBigNumStatecontext of the ciphertext for each decryption operation.
- pKeys[8]
- Pointer to theIppsRSAPublicKeyStatecontext for each decryption operation.
- statuses
- Pointer to theIppStatusarray that contains statuses for each decryption operation.
- pScratchBuffer
- Pointer to the temporary buffer of size not less than returned by theRSA_MB_GetBufferSizePrivateKeyfunction.
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
.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 isNULL.
- ippStsSizeErr
- Indicates an error condition if the size of modulusnin one context is not equal to the size of the modulusnin 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.
