source · ```
pub fn compute_hmac_for_data(
digest_type: ChecksumType,
key: &[u8],
data: &[u8],
) -> GString
```

## Expand 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.

### §`digest_type`

a #GChecksumType to use for the HMAC

### §`key`

the key to use in the HMAC

### §`data`

binary blob to compute the HMAC of

## §Returns

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