| michael@0 | 43 | * |
| michael@0 | 44 | * First, |data| is the final string value produced by the cryptohash. |for (i in |
| michael@0 | 45 | * data)| uses the Mozilla JS extension that iterating over a string iterates over |
| michael@0 | 46 | * its character indexes, so that's 0..length-1 over the hash string. |
| michael@0 | 47 | * |
| michael@0 | 48 | * Returning to the left, the |charCodeAt| gets the value of the character at that |
| michael@0 | 49 | * index in the string. |
| michael@0 | 50 | * |
| michael@0 | 51 | * |slice(-2)| is equivalent to |slice(length of this string - 2)| as a convenient |
| michael@0 | 52 | * way of wrapping around to the other end of a string without doing the actual |
| michael@0 | 53 | * calculation. When provided with only one argument, slice selects to the end of |
| michael@0 | 54 | * the string, so this chomps off the last two characters of the string. |
| michael@0 | 55 | * |
| michael@0 | 56 | * The last-two-characters part clarifies the |"0" +| -- if the Unicode value is |
| michael@0 | 57 | * <10, we have a single-character hex string when we want one that's two |
| michael@0 | 58 | * characters, and unconditionally prepending a "0" solves the problem. |
| michael@0 | 59 | * |
| michael@0 | 60 | * The array comprehension just creates an array whose elements are these |
| michael@0 | 61 | * two-character strings. |
