// SockaddrALG implements the Sockaddr interface for AF_ALG type sockets.
// SockaddrALG enables userspace access to the Linux kernel's cryptography
// subsystem. The Type and Name fields specify which type of hash or cipher
// should be used with a given socket.
//
// To create a file descriptor that provides access to a hash or cipher, both
// Bind and Accept must be used. Once the setup process is complete, input
// data can be written to the socket, processed by the kernel, and then read
// back as hash output or ciphertext.
//
// Here is an example of using an AF_ALG socket with SHA1 hashing.
// The initial socket setup process is as follows:
//
// // Open a socket to perform SHA1 hashing.
// fd, _ := unix.Socket(unix.AF_ALG, unix.SOCK_SEQPACKET, 0)
// addr := &unix.SockaddrALG{Type: "hash", Name: "sha1"}
// unix.Bind(fd, addr)
// // Note: unix.Accept does not work at this time; must invoke accept()
// // manually using unix.Syscall.
// hashfd, _, _ := unix.Syscall(unix.SYS_ACCEPT, uintptr(fd), 0, 0)
//
// Once a file descriptor has been returned from Accept, it may be used to
// perform SHA1 hashing. The descriptor is not safe for concurrent use, but
// may be re-used repeatedly with subsequent Write and Read operations.
//
// When hashing a small byte slice or string, a single Write and Read may
// be used:
//
// // Assume hashfd is already configured using the setup process.
// hash := os.NewFile(hashfd, "sha1")
// // Hash an input string and read the results. Each Write discards
// // previous hash state. Read always reads the current state.
// b := make([]byte, 20)
// for i := 0; i < 2; i++ {
// io.WriteString(hash, "Hello, world.")
// hash.Read(b)
// fmt.Println(hex.EncodeToString(b))
// }
// // Output:
// // 2ae01472317d1935a84797ec1983ae243fc6aa28
// // 2ae01472317d1935a84797ec1983ae243fc6aa28
//
// For hashing larger byte slices, or byte streams such as those read from
// a file or socket, use Sendto with MSG_MORE to instruct the kernel to update
// the hash digest instead of creating a new one for a given chunk and finalizing it.
//
// // Assume hashfd and addr are already configured using the setup process.
// hash := os.NewFile(hashfd, "sha1")
// // Hash the contents of a file.
// f, _ := os.Open("/tmp/linux-4.10-rc7.tar.xz")
// b := make([]byte, 4096)
// for {
// n, err := f.Read(b)
// if err == io.EOF {
// break
// }
// unix.Sendto(hashfd, b[:n], unix.MSG_MORE, addr)
// }
// hash.Read(b)
