Function Documentation

prepare_key()

MOC_EXTERN void prepare_key	(	ubyte *	key_data_ptr,
		sbyte4	key_data_len,
		rc4_key *	key
	)

Computes the RC4 key schedule.

Parameters

key_data_ptr	Buffer of the input key material.
key_data_len	The length of the input key material.
key	Pointer to the key to be prepared.

rc4()

MOC_EXTERN void rc4	(	ubyte *	buffer_ptr,
		sbyte4	buffer_len,
		rc4_key *	key
	)

Performs the RC4 cipher operation. RC4 is a stream cipher and the encryption operation is the same as the decryption operation.

Parameters

buffer_ptr	The buffer of data to be operated on in-place.
buffer_len	The length in bytes of the data to be operated on. This length can be anything non-zero.
key	Pointer to a prepared rc4 key.
