initialization vector

A continuously changing number used in combination with a secret key to encrypt data. Initialization vectors (IVs) are used to prevent a sequence of text that is identical to a previous sequence from producing the same exact ciphertext when encrypted. For example, packets have address fields that are generally fixed in location within the header of the packet. If attackers view the same encrypted data over and over, it provides them with clues to interpret their original values. See nonce.

If you do not want to deal with questions like key sizes, salt lengths, block cipher modes, initialization vectors or iteration count then CrococryptLib is exactly what you need for your software project.
That implies that the router had only strong initialization vectors and other improvements in WEP that typically only forestall cracking by minutes.
