On August 22, 1999, a team of scientists from six different countries, led by Herman te Riele of CWI, found the prime factors of a 512-bit number, whose size models 95% of the keys used for protection of electronic commerce on the Internet. This result shows, much earlier than expected at the start of E-commerce, that the popular key-size of 512 bits is no longer safe against even a moderately powerful attacker.http://www.ercim.org/publication/Ercim_News/enw39/512.html
Arjen Lenstra and Eric Verheul’s methodical estimates give [...] results for the security of 1024-bit RSA keys. In one model, they project that in the year 2009, a machine costing about $250 million could factor a 1024-bit RSA key in a dayhttp://www.rsa.com/rsalabs/node.asp?id=2004
5.3 ID and key maintenance: Creating new IDs with long keys in Notes and Domino 7
When registering certifiers or users in Notes and Domino 7, you need to choose the length for the public key. The default will be 630 bits, which is compatible with all earlier releases. You can change this to 1024 bits if your environment consists entirely of Notes 6, 6.5, and 7 clients and the same releases for your Domino servers.
