Wasn't there a rumor last year that Skype didn't do any encryption
padding, it just did a straight exponentiation of the plaintext?
Would that be safe, if as the report suggests, the data being
encrypted is 128 random bits (and assuming the encryption exponent is
considerably bigger than 3)? Seems like it's probably OK. A bit risky
perhaps to ride bareback like that but I don't see anything inherently
fatal.
