In the refered doc there are several algos defined in dependance of what version of PKZip is used. Furthermore, under "Strong Encryption", from which I hope it is used inside vim (I think I remember earlier posts elsewhere stateing to have broken encrypted zip archives...if my memory serves me right...) I found the following note: "The Strong Encryption technology defined in this specification is covered under a pending patent application. The use or implementation in a product of certain technological aspects set forth in the current APPNOTE, including those with regard to strong encryption or patching, requires a license from PKWARE. Portions of this Strong Encryption technology are available for use at no charge. Contact PKWARE for licensing terms and conditions. Refer to section II of this APPNOTE (Contacting PKWARE) for information on how to contact PKWARE." Is this applicable to out vim ??? Kind regards, mcc PS: AES,Twofish, Blowfish would be alternatives since not covered by patents and explicitely released into the public domain.
