## Description

## Details

### MD5Context

    typedef struct {
    } MD5Context;

### Warning

`MD5Context` is deprecated and should not be used in newly-written code.

A buffer structure used for md5 calculation.

### md5_get_digest ()

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

### Warning

`md5_get_digest` is deprecated and should not be used in newly-written code.

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_from_file ()

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

### Warning

`md5_get_digest_from_file` is deprecated and should not be used in newly-written code.

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_init ()

    void                md5_init                            (MD5Context *ctx);

### Warning

`md5_init` is deprecated and should not be used in newly-written code.

Initialise an md5 buffer.

`ctx` : | md5 context

### md5_update ()

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

### Warning

`md5_update` is deprecated and should not be used in newly-written code.

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_final ()

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

### Warning

`md5_final` is deprecated and should not be used in newly-written code.

copy the final md5 hash to a bufer

`ctx` : | context containing the calculated md5
`digest` : | 16 bytes buffer
