CGOST::CGOST

CGOST( SL_CIPHER_DIR dir, const unsigned char* pKey );

CGOST( SL_CIPHER_DIR dir, const unsigned char* pKey, unsigned int );

Parameters

dir

    [in] Cipher direction. It can be SLC_ENCRYPT or SLC_DECRYPT.

 pKey

    [in] Pointer to the secret key.

The third parameter of type unsigned int was added for consistency with other encryption algorithms and it is ignored.

Remarks

Both constructors work in the same way.

They construct a CGOST object and initialize it with the secret key pointed by pKey. Note that the first CGOST::DEFAULTKEYSIZE bytes of the memory buffer pointed by pKey are used as the secret key.

The CGOST object is initialized for encryption if dir is SLC_ENCRYPT, or it is initialized for decryption if dir is SLC_DECRYPT.

Example

//Define the key for GOST encryption algorithm
char key[CGOST::DEFAULTKEYSIZE] = 
{
    'v','e','r','y','l','o','n','g',

    'p','a','s','s','w','o','r','d',

    '0','1','2','3','4','5','6','7',

    '9','8','7','7','7','2','2','1'
};

//Declare a local CGOST object
CGOST cipher( SLC_ENCRYPT, (const unsigned char*)key );

//Declare a dynamic CGOST object
CGOST* pCipher = new CGOST( SLC_DECRYPT, (const unsigned char*)key );
