Philip Zimmermann's fag page say no. but some examples say this is true. turkish hacker tamer sahin wrote blog, he say dont use pgp. for example maksik has a pgp protected disk, turkish police catch it. 60 days disk cant deciphered, but cia can it. read(turkish) dekart say; Private Disk does not contain any backdoor. Unlike many other software encryption products, Private Disk does not contain backdoors or government induced escrow keys that would allow the police, or any other authority to decrypt your confidential information. Dekart is a company located in the Republic of Moldova, our state does not have laws that force us to add backdoors to encryption software. This means that your data are well-protected, and that the security of your private information has no breaches. Private Disk's encryption mechanisms were certified by NIST, which guarantees that your data are protected against non-government controlled access attempts too. and jetico say; b. We didn't insert any "back (or trap) doors" to the BestCrypt software that would allow recovering the information about the password. Our government does not bind us to insert any "backdoors" to our products, and we ourselves strongly believe that only an owner of data should decide who is allowed to access it. To help our users to answer the question about possible backdoor (and not only for that), we created a freeware document named 'BestCrypt Development Kit', you can download it from our download page. BDK contains source codes for all the encryption and hash algorithms, so you can make sure yourself if they contain any backdoors or not. what is your idea? they are say true? or encryption is lie?
