  GChecksumType digest_type,
  const guchar* key,
  gsize key_len,
  const gchar* str,
  gssize length
)

Description

Computes the HMAC for a string.

The hexadecimal string returned will be in lower case.

 The data is owned by the caller of the function.
key_len gsize
 

The length of the key.
str const gchar*

 The data is owned by the caller of the function.
 The value is a NUL terminated UTF-8 string.
length gssize
 

The length of the string, or -1 if the string is nul-terminated.

Return value

Returns: gchar*
 

The HMAC as a hexadecimal string. 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.
