comment How to checkout only one file from git repository?
I would argue against the statement that git "generates [files] based on the entire history of the project". It is more correct to say that git stores snapshots of the states of files in the form of hash trees. Certainly there is no generating going on.

comment How can I easily encrypt a file?
@David Forester: it is not enough to say "it uses AES and AES has no known vulnerabilities," because just using AES alone is not enough to password-protect a file securely. The WinZip file format (as you linked) also uses PBKDF2 to generate the AES-128 (or AES-256) key (with 1000 iterations), which is important to protect against brute-force attacks, and HMAC-SHA1-80 (truncated to 80 bits) as a MAC, which is also fairly important to prevent tampering. This isn't the most secure system ever; 1000 iterations isn't seen as especially strong these days, and it only gets worse with time.

comment Need a secure password generator recommendation
@Dave: Because it adds no value to do so. This also means sometimes you're creating a password with 33 bits of security, and sometimes with 82 (assuming this is base-62). Here's a better plan: decide what the maximum password length you're willing to have is, and choose a password with that length, or at least long enough that you get 128-bits of security.

@Tito: What? How is an attacker going to guess a 128-bit value?

comment Need a secure password generator recommendation
Why is this the top answer? "Don't worry about password security, it's not important." Password security is one of the most abused, misunderstood problems with security today. Please stop spreading stuff like this. Make your passwords secure.
