Function Documentation

md5()

void md5	(	const void *	in,
		size_t	inlen,
		void *	out
	)

Convenient all-in-one MD5 computation.

Performs md5_init(), md5_update() and md5_final(), and places the resulting hash in out.

Parameters

in	Pointer to data to hash
inlen	Length of in data, in bytes
out	Pointer to location to place the message digest

md5_final()

void md5_final	(	MD5_CTX *	ctx,
		void *	out
	)

Finalize a MD5 message digest.

Generate the MD5 message digest and place in out.

Parameters

ctx	Pointer to MD5 context
out	Pointer to location to place the message digest

md5_init()

void md5_init

(

MD5_CTX *

ctx

)

Initialize a MD5 context.

Parameters

ctx	Pointer to MD5 context

md5_update()

void md5_update	(	MD5_CTX *	ctx,
		const void *	in,
		size_t	inlen
	)

Add inlen bytes from in to a MD5 context for hashing.

Parameters

ctx	Pointer to MD5 context
in	Pointer to data to hash
inlen	Length of in data, in bytes
