new

Creates a new #GChecksum, using the checksum algorithm @checksum_type. If the @checksum_type is not known, null is returned. A #GChecksum can be used to compute the checksum, or digest, of an arbitrary binary blob, using different hashing algorithms.

A #GChecksum works by feeding a binary blob through g_checksum_update() until there is data to be checked; the digest can then be extracted using g_checksum_get_string(), which will return the checksum as a hexadecimal string; or g_checksum_get_digest(), which will return a vector of raw bytes. Once either g_checksum_get_string() or g_checksum_get_digest() have been called on a #GChecksum, the checksum will be closed and it won't be possible to call g_checksum_update() on it anymore.
