Errata ID: 2211
Reported By: Constantin Hagemeier
Date Reported: 2010-04-28
Rejected by: Sean Turner
Date Rejected: 2010-07-20
Section 5.2.2. says:
The details of the calculation are different for DSA signatures than for RSA signatures.
It should say:
The details of the calculation are different for DSA signatures from that for RSA signatures.
different from, not different than
Our research shows that this is a matter of opinion -- in US English grammar, the “different than” is acceptable this way. Jon prefers “different from” (the suggested erratum) and David “different than.” Thus our agreed resolution is to reject, as this is debate over usage, not an actual erratum.
