SecureZIP 12.1: How It Uses Comodo Digital Certificates for Secure File Exchange

Opublikowana właśnie nowa wersja SecureZIP 12.1 znanej firmy PKWARE to dobry pomysł na zabezpieczenie swoich zdjęć. SecureZIP korzysta z systemu kluczy publicznych certyfikowanych przez COMODO (zgodnych ze standardem X.509). Dobre też jest to, że w wersji dla domowych, niekomercyjnych użytkowników program jest bezpłatny.

Getting started with a certificate-based public-key encryption product like PKware's SecureZIP 12.1 or PGP Desktop requires a significant amount of setup. You need to obtain and install your certificate and keys and register the public key in a repository. SecureZIP automates the setup process as much as it can, but it's still a tad arcane. So how does Voltage get away with skipping this step?

WinZip, starting with version 12.1, uses the extension .zipx for ZIP files that use compression methods newer than DEFLATE; specifically, methods BZip, LZMA, PPMd, Jpeg and Wavpack. The last 2 are applied to appropriate file types when "Best method" compression is selected.[28][29]

The mean age of participants was 48.5 years (SD11.6), 33 (75 %) were female, forty three (97.72%) were NZ Europeans and one (2.27%) was Maori. Nineteen participants (43.2 %) were employed and the rest were either unemployed or retired from work. The mean duration of their disease was 12.1 (SD10) years and the mean age at disease onset was 36.4 (SD10.6) years. Twenty-nine participants (65.9 %) did not use an assistive device for ambulation and 15 (34.1%) were assistive device users. Some of the assistive devices the participants used were: 1 stick (n=5), 1 elbow crutch (n=4), 2 elbow crutches (n=2), 1 quadripod (four-legged cane) (n=1) and rollator (rolling walker) (n=3). Four assessments were performed at participant's home and the remaining (n=40) took place at one of the research centres. EDSS assessments for eight participants were performed by a neurologist, and for the remaining 36 participants, their EDSS scores were retrieved from their medical records.
