For 10 points, name these short strings used to restrict access to authorized users.
These objects are usually acted on by MD5 or Blowfish before use. A precomputed list of these via inverted hash is called a rainbow table. Stretching is a technique to increase the effective length of these objects. These are usually stored only in hashed form, and their frequent mutation occurs in a process called aging. The strength of these objects is generally proportional to their length, though poor choices are vulnerable to dictionary attacks, in general brute force attacks occur when a black hat tries every possible combination until one works.
