Function Documentation

void aud_md5_append	(	aud_md5state_t *	ctx,
		const guint8 *	buf,
		guint	len
	)

Appends more data to the MD5 state context.

Updates context to reflect the concatenation of another buffer full of bytes.

Parameters:

ctx	State context to add data in.
buf	Pointer to buffer of data.
len	Length/size of the data in buffer.

Definition at line 154 of file md5.c.

void aud_md5_finish	(	aud_md5state_t *	ctx,
		aud_md5hash_t	digest
	)

Calculates a MD5 hash digest from the given context.

Parameters:

ctx	State context to be hashed.
digest	Variable where computed MD5 digest is placed.

Definition at line 201 of file md5.c.

void aud_md5_init

(

aud_md5state_t *

ctx

)

Start MD5 accumulation.

Set bit count to 0 and buffer to mysterious initialization constants. Initializes the given state context.

Parameters:

ctx	Context structure to initialize.
