## Description

## Details

### MD5Context

    typedef struct {
    } MD5Context;

A buffer structure used for md5 calculation.

MD5Context

### md5_get_digest ()

    void        md5_get_digest                  (const gchar *buffer,
                                                 gint buffer_size,
                                                 guchar digest[16]);

Get the md5 hash of a buffer. The result is put in the 16 bytes buffer digest .

buffer :

  byte buffer

buffer_size :

  buffer size (in bytes)

digest :

  16 bytes buffer receiving the hash code.

md5_get_digest

### md5_get_digest_from_file ()

    void        md5_get_digest_from_file        (const gchar *filename,
                                                 guchar digest[16]);

Get the md5 hash of a file. The result is put in the 16 bytes buffer digest .

filename :

  file name

digest :

  16 bytes buffer receiving the hash code.

md5_get_digest_from_file

### md5_init ()

    void        md5_init                        (MD5Context *ctx);

Initialise an md5 buffer.

ctx :

  md5 context

md5_init

### md5_update ()

    void        md5_update                      (MD5Context *ctx,
                                                 const guchar *buf,
                                                 guint32 len);

Update context to reflect the concatenation of another buffer full of bytes. Use this to progressively construct an md5 hash.

ctx :

  context object used for md5 computaion

buf :

  buffer to add

len :

  buffer length

md5_update

### md5_final ()

    void        md5_final                       (MD5Context *ctx,
                                                 guchar digest[16]);

copy the final md5 hash to a bufer

ctx :

  context containing the calculated md5

digest :

  16 bytes buffer
