I was wondering where "RSA-464" in the article came from.. and found calculation formula, which makes this number to seem incorrect?
bmax - a maximum number of bits required for a decimal number is calculated by this formula:
bmax = ceil(d(log(10)/log(2)))
(where d - number of digits).
log(10)/log(2) = 3.3219280948873623
approximately:
bmax = ceil(d3.3219)
comes to 425 bits key.
