 Adding 2 metadata characters and a clear separator gives us:

 [#217:c44]comment:44:[/tahoe-lafs/trac-2024-07-25/issues/7722](/tahoe-lafs/trac-2024-07-25/issues/7722) says that, if we don't need to prevent collisions, then we can use a K-bit hash for K-bit second-pre-image resistance. However, see [#882:c6]comment:6:[/tahoe-lafs/trac-2024-07-25/issues/8387](/tahoe-lafs/trac-2024-07-25/issues/8387) for a counterargument saying that 50 extra bits or so are needed to be secure against multi-target attacks (i.e. T = 50). This page has now been updated assuming the counterargument is correct.
