gwymd5 — Compute MD5 digest

Functions

void	gwy_md5_get_digest ()

Includes

#include <libgwyddion/gwyddion.h>

Description

MD5 (RFC1321) is a reasonably fast digest function. It can be used for hash key creation and fast data indexing, but should be no longer used for cryptographic and security purposes.

Functions

gwy_md5_get_digest ()

void
gwy_md5_get_digest (const gchar *buffer,
                    gint buffer_size,
                    guchar digest[16]);

gwy_md5_get_digest is deprecated and should not be used in newly-written code.

Compute the MD5 hash of a buffer.

The MD5 algorithm takes as input a message of arbitrary length and produces as output a 128-bit "fingerprint" or "message digest" of the input. For more information see RFC 1321.

This function is trivially replaced by GChecksum with G_CHECKSUM_MD5. It is in fact currently a simple GChecksum wrapper.

Parameters

buffer	A byte buffer.
buffer_size	Size of `buffer` (in bytes) or -1 if `buffer` is nul-terminated.
digest	16 bytes to store the hash code to.
