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]);

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.

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.
