Rijndael128EncryptCCM

DEPRECATED. Encrypts a variable length data stream and generates its authentication tag in the CCM mode.

Syntax

IppStatus ippsRijndael128EncryptCCM_u8(const Ipp8u* pNonce, int nonceLen, const Ipp8u* pAssc, int asscLen, const Ipp8u* pSrc, int srcLen, int macLen, Ipp8u* pDst, const IppsRijndael128Spec* pCtx);

Parameters

pNonce	Pointer to the nonce.
nonceLen	Length of the nonce *pNonce (in octets).
pAssc	Pointer to the assosiated data.
asscLen	Length of the assosiated data *pAssc (in octets).
pSrc	Pointer to the input plaintext data.
srcLen	Length of the input plaintext *pSrc (in octets).
macLen	Length of the authentication tag in octets.
pDst	Pointer to the resulting ciphertext data stream.
pCtx	Pointer to the IppsRijndael128Spec context.

Description

This function is deprecated. Use Rijndael128CCMEncryptMessage instead of it.

This function is declared in the ippcp.h file. The function encrypts the input data stream of a variable length and computes the authentication tag according to the CCM mode, as specified in [NIST SP 800-38C]. Unlike Rijndael128EncryptCCM, Rijndael128EncryptCCM_u8 employs the int data type for all length parameters. Use this function rather than Rijndael128EncryptCCM.

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 length input data does not meet any of the following conditions: 7 ≤ nonceLen ≤ 13 asscLen ≥ 0 srcLen ≥ 1 macLen = 2`n`, 1 ≤ `n` ≤ 8.
ippStsContextMatchErr	Indicates an error condition if the context parameter does not match the operation.
