1. The encryption scheme used for UNIX passwords is one way; it is not possible to reverse it. Therefore, would it be accurate to say that this is, in fact, a hash code rather than an encryption of the password?

2. Assuming that you have successfully answered the preceding problem and understand the significance of the salt, here is another question. Wouldn’t it be possible to thwart completely all password crackers by dramatically increasing the salt size to, say, 24 or 48 bits?
