function compute_checksum_for_string(checksum_type: GLib.ChecksumType, str: String, length: Number(gssize)): String {
    // Gjs wrapper for g_compute_checksum_for_string()
}
  Computes the checksum of a string.
The hexadecimal string returned will be in lower case.
Since 2.16
- checksum_type
- str
