const dsCypher_byte_t *    p_src,
dsCypher_word32_t    p_srcLen
)  [virtual]
 

Perform hash calcualton

Implements dsCryptoHash.

virtual const dsCypher_word32_t dsSHA1::digestSize (    )  [virtual]
 

Implements dsCryptoHash.

dsCypher_byte_t *    c
)  [inline, protected, inherited]

These routines placed here to allow developer to providei os specific implementation, it's not virtual because calling virtual function inside encryption algorithm dramatically decrease performance
