Note: A text list of all duplicate keys by short keyid listed on this page is available in duplicate_keyids (signature).

Update: Yet even more duplicates are found, esp. when using raw pubkey packets to further disambiguate keys, even "identical" v2 and v3 keys or v3 keys with different timestamps, for example.

This brings the number of duplicate short keyids on v4 keys to 70. Given 152 duplicate short keyids in total, 46.1% are v4 keys.

In the 2002-02-01 keydump of pgp.cc.gatech.edu, there are 5 duplicate long (64 bit) keyids and 81 duplicate short (32 bit) keyids, out of 1,623,342 keys. This previous survey from 1999-07-09 can be used for a comparison. The duplicates by long keyid all appear to be two versions of the same key (all are pre-v4 RSA with slightly-mangled moduli in the bits before the last 64 (the keyid)): 

  1. 0x6B2B5E51E879DAF5 (0xE879DAF5, also #73 below)

  2. 0xA88984546775FEF5 (0x6775FEF5, also #26 below)

  3. 0xBC3A4EB1DE0E525D (0xDE0E525D, also #69 below)

  4. 0xD1FAB1B9D6DC8A3D (0xD6DC8A3D, also #65 below)

  5. 0xF8CC5575CFA87201 (0xCFA87201, also #60 below)
The duplicates by short keyid (note that there are two 0xDEADBEEF duplicates): 
  1. 0x00000001 (neither are v4)

  2. 0x0332405D (one v4)
