There is the vigenère cipher, which is pretty strong but relativeley easy to "hand-code"
The best search algorithm to use for a sorted array is the binary search algorithm.

Yes, Dijkstra's algorithm is a greedy algorithm because it makes decisions based on the current best option without considering future consequences.
The quicksort algorithm is considered the best for efficiency and performance among sorting algorithms.
One of the best property of an algorithm is that it is simple. It can not be too long and ambiguous, it has to be straightforward, with understandable variables as used also in a pseudocode.
The usual definition of an algorithm's time complexity is called Big O Notation. If an algorithm has a value of O(1), it is a fixed time algorithm, the best possible type of algorithm for speed. As you approach O(∞) (a.k.a. infinite loop), the algorithm takes progressively longer to complete (an algorithm of O(∞) would never complete).
These are terms given to the various scenarios which can be encountered by an algorithm. The best case scenario for an algorithm is the arrangement of data for which this algorithm performs best. Take a binary search for example. The best case scenario for this search is that the target value is at the very center of the data you're searching. So the best case time complexity for this would be O(1). The worst case scenario, on the other hand, describes the absolute worst set of input for a given algorithm. Let's look at a quicksort, which can perform terribly if you always choose the smallest or largest element of a sublist for the pivot value. This will cause quicksort to degenerate to O(n2). Discounting the best and worst cases, we usually want to look at the average performance of an algorithm. These are the cases for which the algorithm performs "normally."
Elliptical Curve Cryptography.
Yes,there is an obvious algorithm to test each possible trip and find the best one. The trouble is the exponential run-time.
