RSA Security 5 manual 2Algorithm methods for feedback modes

AI_FeedbackCipher

A_RC6_PARAMS structure:

typedef struct	{
unsigned int	rounds;	/* number of rounds (20) */
} A_RC6_PARAMS;

Note: The A_RC6_PARAMS structure requires a parameter specifying the number of rounds. Currently, Crypto-C accepts only 20. Future versions may accept other round counts.
