+ * multiple inputs to the buggy algorithm there exist easily found inputs to
+ * the correct algorithm that produce the same hash. Thus, we optionally

+ * While the bug itself affected the majority of passwords containing

+ * collision-producing way), the anti-collision safety measure affects
+ * only a subset of passwords containing the '\xff' character (not even all of
+ * those passwords, just some of them). This character is not found in valid
+ * UTF-8 sequences and is rarely used in popular 8-bit character encodings.
+ * Thus, the safety measure is unlikely to cause much annoyance, and is a
+ * reasonable tradeoff to use when authenticating against existing hashes that
+ * are not reliably known to have been computed with the correct algorithm.
+ *
+ * We use an approach that tries to minimize side-channel leaks of password
+ * information - that is, we mostly use fixed-cost bitwise operations instead
+ * of branches or table lookups. (One conditional branch based on password
+ * length remains. It is not part of the bug aftermath, though, and is
+ * difficult and possibly unreasonable to avoid given the use of C strings by
+ * the caller, which results in similar timing leaks anyway.)
+ *
+ * For actual implementation, we set an array index in the variable "bug"
+ * (0 means no bug, 1 means sign extension bug emulation) and a flag in the
+ * variable "safety" (bit 16 is set when the safety measure is requested).
