Detailed Description

APIs to hash data using the Message-Digest Algorithm 5 (MD5)

Macro Definition Documentation

VLC_HASH_MD5_DIGEST_HEX_SIZE

#define VLC_HASH_MD5_DIGEST_HEX_SIZE   33

MD5 digest hex representation size.

VLC_HASH_MD5_DIGEST_SIZE

#define VLC_HASH_MD5_DIGEST_SIZE   16

MD5 digest output size.

Typedef Documentation

vlc_hash_md5_t

typedef struct vlc_hash_md5_ctx vlc_hash_md5_t

MD5 hash context.

Function Documentation

vlc_hash_md5_Finish()

void vlc_hash_md5_Finish	(	vlc_hash_md5_t *	ctx,
		void *	output,
		size_t	size
	)

Finish MD5 hash computation.

Finishes the MD5 hash computation and provides the hash for the concatenation of all provided data by previous calls to vlc_hash_md5_Update. The result is written to the buffer pointed to by output, which must be at least VLC_HASH_MD5_DIGEST_SIZE big.

Parameters

[in,out]	ctx	MD5 hash context to finish
[out]	output	Output buffer to write to
	size	Output buffer size

vlc_hash_md5_Init()

void vlc_hash_md5_Init

(

vlc_hash_md5_t *

ctx

)

Initialize MD5 context.

Initializes the given MD5 hash function context, if the context is already initialized, it is reset.

Parameters

[out]

ctx

MD5 hash context to init

vlc_hash_md5_Update()

void vlc_hash_md5_Update	(	vlc_hash_md5_t *	ctx,
		const void *	data,
		size_t	size
	)

Update MD5 hash computation with new data.

Updates the context with provided data which is used for the hash calculation. Can be called repeatedly with new data. The final hash represents the hash for the concatenation of all data.

Parameters

[in,out]	ctx	MD5 hash context to update
	data	Data to add
	size	Size of the data to add
