364. Warning messages about key lengths
37
38Commercial SSH's ssh-keygen program contained a bug which caused it to
39occasionally generate RSA keys which had their Most Significant Bit
40(MSB) unset. Such keys were advertised as being full-length, but are
41actually only half as secure.
42
43OpenSSH will print warning messages when it encounters such keys. To
44rid yourself of these message, edit you known_hosts files and replace
45the incorrect key length (usually "1024") with the correct key length
46(usually "1023").
