631	631	// Here is an example of using an AF_ALG socket with SHA1 hashing.
632	632	// The initial socket setup process is as follows:
633	633	//
634		// // Open a socket to perform SHA1 hashing.
635		// fd, _ := unix.Socket(unix.AF_ALG, unix.SOCK_SEQPACKET, 0)
636		// addr := &unix.SockaddrALG{Type: "hash", Name: "sha1"}
637		// unix.Bind(fd, addr)
638		// // Note: unix.Accept does not work at this time; must invoke accept()
639		// // manually using unix.Syscall.
640		// hashfd, _, _ := unix.Syscall(unix.SYS_ACCEPT, uintptr(fd), 0, 0)
	634	// // Open a socket to perform SHA1 hashing.
	635	// fd, _ := unix.Socket(unix.AF_ALG, unix.SOCK_SEQPACKET, 0)
	636	// addr := &unix.SockaddrALG{Type: "hash", Name: "sha1"}
	637	// unix.Bind(fd, addr)
	638	// // Note: unix.Accept does not work at this time; must invoke accept()
	639	// // manually using unix.Syscall.
	640	// hashfd, _, _ := unix.Syscall(unix.SYS_ACCEPT, uintptr(fd), 0, 0)
641	641	//
642	642	// Once a file descriptor has been returned from Accept, it may be used to
643	643	// perform SHA1 hashing. The descriptor is not safe for concurrent use, but

646	646	// When hashing a small byte slice or string, a single Write and Read may
647	647	// be used:
648	648	//
649		// // Assume hashfd is already configured using the setup process.
650		// hash := os.NewFile(hashfd, "sha1")
651		// // Hash an input string and read the results. Each Write discards
652		// // previous hash state. Read always reads the current state.
653		// b := make([]byte, 20)
654		// for i := 0; i < 2; i++ {
655		// io.WriteString(hash, "Hello, world.")
656		// hash.Read(b)
657		// fmt.Println(hex.EncodeToString(b))
658		// }
659		// // Output:
660		// // 2ae01472317d1935a84797ec1983ae243fc6aa28
661		// // 2ae01472317d1935a84797ec1983ae243fc6aa28

	650	// hash := os.NewFile(hashfd, "sha1")

	652	// // previous hash state. Read always reads the current state.
	653	// b := make([]byte, 20)
