对称算法运算类

对称算法运算类接口支持如下，接口定义符合GM/T 0018-2012标准，接口参数与返回值可参考标准文档，算法标识描述可参考GM/T 0006-2012。

其中SDF_Encrypt中puiEncDataLength大于等于输入的明文长度。

SDF_Decrypt中puiDataLength大于等于输入的密文长度。

int SDF_Encrypt(void *hSessionHandle, void *hKeyHandle, unsigned int uiAlgID, unsigned char *pucIV, unsigned char *pucData, unsigned int uiDataLength, unsigned char *pucEncData, unsigned int *puiEncDataLength);
int SDF_Decrypt(void *hSessionHandle, void *hKeyHandle, unsigned int uiAlgID, unsigned char *pucIV, unsigned char *pucEncData, unsigned int uiEncDataLength, unsigned char *pucData, unsigned int *puiDataLength);
int SDF_CalculateMAC(void *hSessionHandle, void *hKeyHandle, unsigned int uiAlgID, unsigned char *pucIV, unsigned char *pucData, unsigned int uiDataLength, unsigned char *pucMAC, unsigned int *puiMACLength);

参考GM/T 0018-2023标准实现了单包可鉴别加解密接口，数据类型与2012版保持一致，为无符号整型。

其中SDF_AuthEnc接口中puiEncDataLength需要大于等于输入的明文长度。

SDF_AuthDec接口中puiDataLength需要大于等于输入的密文长度。

int SDF_AuthEnc(void *hSessionHandle, void *hKeyHandle, unsigned int uiAlgID, unsigned char *pucStartVar, unsigned int uiStartVarLength, unsigned char *pucAad, unsigned int uiAadLength, unsigned char *pucData, unsigned int uiDataLength, unsigned char *pucEncData, unsigned int *puiEncDataLength, unsigned char *pucAuthData, unsigned int *uiAuthDataLength);
int SDF_AuthDec(void *hSessionHandle, void *hKeyHandle, unsigned int uiAlgID, unsigned char *pucStartVar, unsigned int uiStartVarLength, unsigned char *pucAad, unsigned int uiAadLength, unsigned char *pucAuthData, unsigned int *puiAuthDataLength, unsigned char *pucEncData, unsigned int uiEncDataLength, unsigned char *pucData, unsigned int *puiDataLength);

参考GM/T 0018-2023标准实现了多包可鉴别加解密接口。

int SDF_AuthEncInit(void *hSessionHandle, void *hKeyHandle, unsigned int uiAlgID, unsigned char *pucStartVar,
unsigned int uiStartVarLength, unsigned char *pucAad, unsigned int uiAadLength, unsigned int uiDataLength);
int SDF_AuthEncUpdate(void *hSessionHandle, unsigned char *pucData, unsigned int uiDataLength,
unsigned char *putEncData, unsigned int *puiEncDataLength);
int SDF_AuthEncFinal(void *hSessionHandle, unsigned char *pucLastEncData, unsigned int *puiLastEncDataLength,
unsigned char *pucAuthData, unsigned int *puiAuthDataLength);
int SDF_AuthDecInit(void *hSessionHandle, void *hKeyHandle, unsigned int uiAlgID, unsigned char *pucStartVar,
unsigned int uiStartVarLength, unsigned char *pucAad, unsigned int uiAadLength, unsigned char *pucAuthData,
unsigned int uiAuthDataLength, unsigned int uiDataLength);
int SDF_AuthDecUpdate(void *hSessionHandle, unsigned char *pucEncData, unsigned int uiEncDataLength,
unsigned char *pucData, unsigned int *puiDataLength);
int SDF_AuthDecFinal(void *hSessionHandle, unsigned char *pucLastData, unsigned int *puiLastDataLength);

参考GM/T 0018-2023标准实现了多包加解密接口。

int SDF_EncryptInit(void *hSessionHandle, void *hKeyHandle, unsigned int uiAlgID, unsigned char *pucIV,
unsigned int uiIVLength);
int SDF_EncryptUpdate(void *hSessionHandle, unsigned char *pucData, unsigned int uiDataLength,
unsigned char *pucEncData, unsigned int *puiEncDataLength);
int SDF_EncryptFinal(void *hSessionHandle, unsigned char *pucLastEncData, unsigned int *puiLastEncDataLength);
int SDF_DecryptInit(void *hSessionHandle, void *hKeyHandle, unsigned int uiAlgID, unsigned char *pucIV,
unsigned int uiIVLength);
int SDF_DecryptUpdate(void *hSessionHandle, unsigned char *pucEncData, unsigned int uiEncDataLength,
unsigned char *pucData, unsigned int *puiDataLength);
int SDF_DecryptFinal(void *hSessionHandle, unsigned char *pucLastData, unsigned int *puiLastDataLength);
