If keys are involved then the main question is: How secure / reliable are they and their usage? The most important rule in cryptography is not "Make it even more secure" but "(1) Think about how much security you need. (2) Decide which technical effort seems necessary (lower limit) and reasonable (upper limit) to fulfill these requirements. (3) Strictly observe the rules you have determined (write them down). (4) If other people are involved (which usually is the case) let them know precisely and securely what the usage limits and the security level of this key are." Most of the following considerations are about the security and the transparency of their security and meaning.
