The RSA algorithm will work with keys of any length and longer is stronger.
But less than 2048 is not acceptably secure by today's standards and the
sad part is that going beyond 2048 bits doesn't improve it by very much.
Add one bit to the key size of a symmetric cipher like AES and you double
t
There are currently two sets of preferred curves.
CABForum approved use of the NIST curves from Suite B at 384 bits (and
521??) several years ago. Those are currently the only curves for which
FIPS-140 certified HSMs are currently available and thus the only ones that
can be supported by WebPKI CA
For many people involved in developing cryptographic infrastructures,
politics are a major concern.
Getting the politics correct is important.
The true power in this world lies in shaping what people believe. What my
friend Joe Nye calls 'soft power'. To suggest that choice of language is
