Most particularly, asymmetric algorithms such as RSA typically require
far more bits than do symmetric algorithms such as RC4. But sure, it
also varies by individual cipher of course.
My point was that 128 bits isn't much for *any* symmetric cipher. So
calling this "high-grade encryption" is somewhat misleading.
2,048 bits for the RSA cipher, OTOH, should be safe for a while yet...
