Lovecard>is there any weakness on smartcards with rsa encryption

2600-Wiz> the problem is the rsa encryption... RSA hasn't been broken, although it is vulnerable to WEAK KEY VALUES.
a weak value is a key that produces at least one repeated value, for every additional bit in the encryption key, the search time increase exponentially .

It kinda outlines the issues and problmes with cracking RSA and related algorithms.

RSA is very expensive to crack... IT CAN BE CRACKED, but not w/your desktop computer. I 'm leaving in 5 minutes
