- The PKZIP 1.10 AV system is very easy to crack (many tools are available
- for this purpose). Therefore it is useless and meaningless to support them.
- BTW The new AV scheme has been reported to even weaker. See sci.crypt for
- more information. The ARJ security envelope has been cracked as well BTW.
- IMO only HPACK has a proper AV implementation. (it uses RSA)
