[cypherpunks list, 1996] An attack on a public-key cryptosystem
consisting of publishing a key having the same ID as another key
(thus making it possible to spoof a user's identity if recipients
aren't careful about verifying keys). In PGP and GPG the key ID is
the last eight hex digits of (for RSA keys) the product of two
primes. The attack was demonstrated by creating a key whose ID was
0xdeadbeef (see {DEADBEEF}).
