PGP - Keyring Statistic

This is based on the keyring from the CH-Keyserver by November, 16th, 1999.

New statistics can be found at http://dtype.org/keyanalyze/

Background Information

Usable for WOT means: key is self signed, key is not revoked, key has at least one valid userID and key has at least 2 signatures (including the self signature)

Keys with the experimental public key algorithm 100 have been omitted.

The following signatures have been discarded:

Statistical Data

RSA (Encrypt or Sign)

There are 109292 public keys with this algorithm
Number of self signed Keys:   77125 (70.57%)
Revoked Keys:                  6997 ( 6.4 %)
Keys with no valid UID:         494 ( 0.45%)
Keys usable for WOT:          27046 (24.75%)

'General' and 'positiv cert' signatures under keys with public key algoritm RSA (Encrypt or Sign):
