comment Is this a secure way of storing passwords?
@Cthulhu the way the OP proposes it, concatenating random characters (if really random, will include non-printable characters too) avoid the problems that the article tries to explain.

comment Is this a secure way of storing passwords?
@Cthulhu so the answer should have stated that. The way it is, it's wrong. Hashing many times is good if you add the salt (and the pepper, why not). The article is based on a wrong assumption: the 14-printable characters have LESS entropy than the 20 hex-characters hash.

comment Password protect an excel file for a period of time?
@MOTS If the file is really important, that would attract attention from people who really want it, consider it impossible. If you want to protect against a 5 year old boy who wants it, perhaps you can... :) It really depends on the resources of your enemy.

it would be much harder than that. If someone is able to see a file, he is also able to take a photo or film it.

comment Password protected zip opened in notepad
When did you create that .zip file? Did you use strong password or it was a time when you knew little and just used lowercase letters? If so, try bruteforcing it with some program like FZC. In modern computers, weak passwords are easily cracked.

comment I need two separate hidden volumes in disk encryption. What are my options?
@superuser :) take care when doing things "for fun" in security realms. You might end up without your data or without security...
