What are non-control ASCII characters

In order to create a password on a certain web site, one of the requirements is to use least eight non-ascii control characters. I should know this, and I have a hunch it's very obvious, but can someone answer? I used what I thought would qualify, but maybe I didn't use enough.

Which is it non-control ASCII characters as in your title or non-ASCII control characters as in your text? I suspect your title is correct in which case any upper or lower alphanumeric character or symbol should work. Other than resorting to hexadecimal or binary code I can't figure out how one would go about entering non-ASCII control characters. In any case you can find the ASCII character set here which contains a list of the ASCII control characters, the printable ASCII characters, and the extended ASCII character set.


If we knew what it was we were doing, it wouldn't be called research, would it?

Sorry. I'll cut and paste:

"Password requires 8-20 non-control ascii characters"

The shorter answer is there are 32 'control characters' prior to the 'printable' 96 in the low-bit ascii range 0-127. Many of the control chars are used for special keys such as arrows, return, and escape. It's pretty rare to find any password system that will accept non-printable characters.

I you want to get exotic with your password characters, you can go with the symbols, tho the ones that are NOT above the numbers are actually the less-used and may be slightly more secure.

ASCII characters are letters, numbers, and standard punctuation marks that do not have accent marks or non-English characters. Every character in this post, for example, is a non-control ASCII character.

"Non-control ASCII characters" is brain-dead computer-programmer-speak for "numbers, English letters, and standard punctuation." Whatever user interface designer wrote that message needs to be fired.
