QuickCrypt Library

API

SL_DES_Init

void SL_CRYPTCALL SL_DES_Init( void* pContext, int nDir, const void* pKey, unsigned int nKeyLen );

Parameters

pContext

    [out] Pointer to the memory buffer that will be used as a context.

nDir

    [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. This parameter was added for consistency with other encryption algorithms and it is ignored. The algorithm always uses the first SLC_DES_DEFAULTKEYSIZE bytes of the memory buffer pointed by pKey as secret key.

Remarks

Initializes the context pointed by pContext with the secret key pointed by pKey. The context is initialized for encryption if nDir is SLC_ENCRYPT, or it is initialized for decryption if nDir is SLC_DECRYPT.

Before calling SL_DES_Init allocate at least SLC_DES_CONTEXTSIZE bytes for the context.

Example

See the example for SL_DES_ProcessBlock.
