Function Documentation

MHD_MD5_deinit()

void MHD_MD5_deinit

(

struct Md5CtxExt *

ctx

)

Free allocated resources.

Parameters

ctx	the calculation context

MHD_MD5_finish_reset()

void MHD_MD5_finish_reset	(	struct Md5CtxExt *	ctx,
		uint8_t	digest[MD5_DIGEST_SIZE] )

Finalise MD5 calculation, return digest, reset hash calculation.

Parameters

	ctx	the calculation context
[out]	digest	set to the hash, must be MD5_DIGEST_SIZE bytes

Definition at line 84 of file md5_ext.c.

MHD_MD5_init_one_time()

void MHD_MD5_init_one_time

(

struct Md5CtxExt *

ctx

)

Initialise structure for MD5 calculation, allocate resources.

This function must not be called more than one time for ctx.

Parameters

ctx	the calculation context

MHD_MD5_update()

void MHD_MD5_update	(	struct Md5CtxExt *	ctx,
		const uint8_t *	data,
		size_t	length )

MD5 process portion of bytes.

Parameters

ctx	the calculation context
data	bytes to add to hash
length	number of bytes in data

Process portion of bytes.

Parameters

ctx	the calculation context
data	bytes to add to hash
length	number of bytes in data
