The following table shows the frequency breakdown, by key generation month, just over the past year, of the approx. 3300 public keys that are available on the public key servers (I used the one at <public-key-server@martigny.ai.mit.edu>). Note that I've included revoked keys, but there are only 19 of these from the same time period. In other words, of the keys out there, 211 of them were generated in March of 1993, 216 in April, etc. I have no idea if these numbers correlate well to actual PGP use (these are, after all, just the people who are activist enough to post their key on the public key server, which also requires some degree of Internet connectivity). If the numbers DO correlate to some degree, I thought it was interesting that they appear to show a recent decline in usage rather than a steady ramp-up. Is the trend toward universal crypto slacking off?
