Yes, it's standard. I seem to remember reading somewhere that it could
be used for text that contained something that might offend somebody,
that way only those who want to read it can read it and nobody has to
accidentally read something he/she doesn't want to read... The coding is
just there to "blur" the text for the human eye...

This little C program will "scramble"/"unscramble" text for you:


#include <stdlib.h>
#include <stdio.h>

main()
{
  int ch;

  while ((ch = getchar()) != EOF)
    {
      if ((ch >= 65) && (ch <= 90))
	{
	  ch = 65 + ((ch - 65) + 13) % 26;
	}
      if ((ch >= 97) && (ch <= 122))
	{
	  ch = 97 + ((ch - 97) + 13) % 26;
	}
      printf("%c", ch);
    }
}
