GLibcompute_hmac_for_data

since: 2.30

Declaration 

gchar*
g_compute_hmac_for_data (
  GChecksumType digest_type,
  const guchar* key,
  gsize key_len,
  const guchar* data,
  gsize length
)

Description

Computes the HMAC for a binary data of length. This is a convenience wrapper for g_hmac_new(), g_hmac_get_string() and g_hmac_unref().

The hexadecimal string returned will be in lower case.

Available since: 2.30

Parameters

digest_type

Type: GChecksumType

A GChecksumType to use for the HMAC.

key

Type: An array of guchar

The key to use in the HMAC.

The length of the array is specified in the key_len argument.
The data is owned by the caller of the function.
key_len

Type: gsize

The length of the key.

data

Type: An array of guchar

Binary blob to compute the HMAC of.

The length of the array is specified in the length argument.
The data is owned by the caller of the function.
length

Type: gsize

Length of data.

Return value

Type: gchar*

The HMAC of the binary data as a string in hexadecimal. The returned string should be freed with g_free() when done using it.

The caller of the function takes ownership of the data, and is responsible for freeing it.
The value is a NUL terminated UTF-8 string.
