Last week an international team of researchers broke the 768bit RSA key using several hundred computers, The Register reports.
It’s interesting news but has little practical value, however, the part of the article everyone should read is:
More importantly, it means it’s only a matter of another decade or so – sooner assuming there’s some sort of breakthrough in NFS or some other form of mathematical factoring – until the next largest RSA key size, at 1024 bits, is similarly cracked.
There are several so-called “enterprise” products that are using 1024 bit RSA keys. I have been claiming for years that those were totally inadequate even for a security-conscious prosumer, much less for a large corporate or government.
Now finally a best before date can be slapped on those, and it’s 10 years or less. No one should have such small RSA keysizes, now is the time to upgrade.
