QuickCrypt Library

C++ Interface

CBlowfish::Init

void Init( SL_CIPHER_DIR dir, const unsigned char* pKey );

void Init( SL_CIPHER_DIR dir, const unsigned char* pKey, unsigned int nKeyLen );
 

Parameters

dir

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

 pKey

    [in] Pointer to the secret key.

 nKeyLen

    [in] Length in bytes of the key. It can be in the range 1 through 72 bytes.

Remarks

Both member functions initialize the CBlowfish object with the secret key pointed by pKey. Note that if nKeyLen it is not indicated, the first CBlowfish::DEFAULTKEYSIZE bytes of the memory buffer pointed by pKey are used as the secret key.

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

Example

See the example for CBlowfish::ProcessBlock.
