Unicode symbol U+1F44C (👌) represents this gesture.
US Air Force Lt. Col. John "Shorty" Powers popularized the expression "A-ok" while NASA's public affairs officer for Project Mercury, attributing it to astronaut Alan Shepard during his Freedom 7 flight. In his book The Right Stuff, however, author Tom Wolfe wrote that Powers had borrowed it from NASA engineers who used it during radio transmission tests because the sharper sound of A cut through the static better than O. Apparently, the first documented use "A-ok" is contained within a memo from Tecwyn Roberts, Flight Dynamics Officer, to Flight Director (entitled "Report on Test 3805", dated Feb 2, 1961) in penciled notes on the countdown of MR-2, dated Jan 31, 1961.
Multiple meanings 
While the gesture is positive in some countries, in certain parts of middle and southern Europe (although not in Spain or Portugal) the gesture is considered offensive, as in you are a zero or you are nothing. In some Mediterranean countries such as Turkey, as well as in Brazil, it represents vulgar expressions: either an insult (you are an asshole), or the slang for anus itself. By the same symbolism, it stands for (faggot) in several South American countries.
Positive connotation 
In Australia and Portugal, it can either mean okay or zero.
In Finland, it is used to celebrate ending of the national service. During their final day in the Finnish Defence Forces, conscripts use it to denote they have zero days left in their service, and that they will receive an honorable discharge during the course of that day. It is also used to tease and taunt other conscripts that still have various numbers of days left, and are stuck while their comrades are allowed to leave. Colloquially, it is referred to as the TJ0 or 'Tänään jäljellä 0 aamua', which translates to 'Zero mornings left today'. The official TJ counter can be viewed on the Finnish Defence Forces website.
In underwater diving, it widely means both Are you okay?, and its response Yes, I'm OK, or just I'm OK. It can be confusing for beginners, because using the thumbs up gesture rather than the A-ok gesture signals that the person making that gesture wants to ascend (to the surface).
In basketball, players sometimes use this gesture to show they just made a three pointer.
Negative connotation 
In Venezuela, as well as Turkey, it is a very offensive gesture, regarded as a reference to homosexuality, and reflecting a wider than usual (due to anal sex) anus of a homosexual man. In Peru too, but it is upside-down with the middle, ring and little fingers pointing down.. In Brazil it is also an offensive gesture, equivalent to showing the middle finger.
In most continental European countries, when the sign is placed over the nose, with the nose protruding through the O made by the thumb and forefinger, it means drunk. The origins of this sign may stem from the hand gesture holding a bottle's head while drinking. As a bottle with alcoholic liquid is implied this refers to drinking or the state of being drunk.
Some Occultists view it as the number 666 due to the circle and the three fingers behind it. The sign is associated with the Illuminati or Freemasonry by some conspiracy theorists, especially when shown in the media, especially when used by certain entertainers.
