To negate a set or a range, you use the caret character ( ^) at the beginning of the set and range. For example, the range [^0-9] matches any character except a digit. It is the same as the character set \D. Notice that regex also uses the caret ( ^) as an anchor that matches at the beginning of a string. cryptographic service windows 10Web15. Using non-greedy quantifiers here is probably the best solution, also because it is more efficient than the greedy alternative: Greedy matches generally go as far as they can (here, until the end of the text!) and then trace back character after character to try and match the part coming afterwards. crypto falling apart
