| 85 | * The tag is now still a single octet, but the |
| 86 | * upper 4 bits are interpreted as a version. Previous format |

| 91 | * (Bad app, no cookie!) Thus, we leave the _PW_KEY* symbols at their |
| 92 | * old values so these apps still work. Consequently |
| 93 | * we have to muck around a bit more to get the correct, versioned |
