7-Zip Doesn't Ask Me For A Password For A ZIP File I Encrypted While Double-clicking It

Answer : The ZIP format doesn't allow for encrypting file lists. This means that file lists are viewable by anyone. Only the contents of the files is encrypted, which means that no one can read the file without your password. Due to this, 7-Zip only asks for your password before unzipping. If you need a format that encrypts the file list, use 7Z and make sure you check "Encrypt File Names". For the more technical minded, the ZIP specification doesn't allow for encryption of the Central Directory. You will be prompted for a password when you try to extract the files. To simply view the contents of the archive does not require a password. If you would like to obfuscate the contents of the archive, compress the directory into an archive, and then compress that archive with a password. Thus, you will have to extract the archive with a password, to pull out the archived (and obfuscated) contents. A generalized solution that works for all zip programs (WI...

Chrome Not Saving Passwords On Mac

Image
Answer : I had the same issue when my IT folks at work nuked my keychain. I uninstalled and installed chrome following the steps here. Go to ~/<username>/Library folder. Delete Google folder from ~/Library/Application Support . Delete below folders from ~/Library/Caches Delete ~/Library/Google folder Make sure you’ve shut down Chrome while performing this action and then either move the folder to the trash or rename it to something like backup. Chrome and then start Chrome up again. This will fresh start your Google Chrome. An important addition to this comprehensive answer. This will only work if you sign out of your Google account in Chrome. I tried this method several times and it wasn't until I signed out of Chrome, then deleted all the cached items and the Google folder in the Library folder that my passwords were restored. Also, another tip (as osx has been updated). To view the Library folder, when in the User folder cl...

Chrome Not Asking To Remember Passwords

Answer : From Google's help: Make Chrome ask to save passwords again If you told Chrome to never offer to save your password for a specific site, but you change your mind, you can bring back the option. On your computer, open Chrome. At the top right, click More More and then Settings. At the bottom, click Show advanced settings. Under "Passwords and forms," click Manage passwords. A box will appear with a list of saved passwords. In the "Never saved" section, select the website and click Delete Delete. Click Done. If Chrome isn't asking to save any passwords anymore, you may have asked it to stop saving passwords. Bring back the prompt by turning "Offer to save your web passwords" back on. Chrome isn't saving passwords If you've told Chrome to save a password but it's not showing up, try deleting and resaving it. Open your list of saved passwords, and check for the website. ...

Brother Printer Firmware Update Password Reset

Answer : I spent many hours doing a variety of factory resets and trying the password above, "access". Apparently, Brother pushed out a firmware update recently which changed the default password on many devices to "initpass". So, if you are locked out of the web interface give this a try. help.brother-usa.com It looks like you might be able to reset to factory settings via the control panel on the device as well. From Brother's FAQ: Via the control panel (only for network ready models) Make sure the machine is not operating, then disconnect all the cables from the machine (except power cable). Press the Menu or Menu/Set key on the control panel. Press up or down navigation key to select LAN or Network and press Set, Menu/Set or OK . Press up or down navigation key to select Factory Reset or Network Reset and press Set, Menu/Set or OK . Select Reset . Select Yes . The machine will re-start, re-connect cables once this is complete.

Calculating Password Entropy?

Answer : There are equations for when the password is chosen randomly and uniformly from a given set; namely, if the set has size N then the entropy is N (to express it in bits, take the base-2 logarithm of N ). For instance, if the password is a sequence of exactly 8 lowercase letters, such that all sequences of 8 lowercase characters could have been chosen and no sequence was to be chosen with higher probability than any other, then entropy is N = 26 8 = 208827064576 , i.e. about 37.6 bits (because this value is close to 2 37.6 ). Such a nice formula works only as long as uniform randomness occurs, and, let's face it, uniform randomness cannot occur in the average human brain. For human-chosen passwords, we can only do estimates based on surveys (have a look at that for some pointers). What must be remembered is that entropy qualifies the password generation process , not the password itself. By definition, "password meter" applications and Web sites do ...

Can Anyone Confirm That PhpMyAdmin AllowNoPassword Works With MySQL Databases?

Answer : Copy config.sample.inc.php to config.inc.php . In most cases you will find the config file on linux: /etc/phpmyadmin/config.inc.php on mac: /Library/WebServer/Documents/phpmyadmin/config.inc.php If you are trying to log in as root, you should have the following lines in your config: c f g [ ′ S e r v e r s ′ ] [ cfg['Servers'][ c f g [ ′ S er v er s ′ ] [ i]['user'] = 'root'; c f g [ ′ S e r v e r s ′ ] [ cfg['Servers'][ c f g [ ′ S er v er s ′ ] [ i]['AllowNoPassword'] = true; According to this: https://www.simplified.guide/phpmyadmin/enable-login-without-password This $cfg['Servers'][$i]['AllowNoPassword'] = TRUE; should be added twice in /etc/phpmyadmin/config.inc.php if (!empty($dbname)) { // other configuration options $cfg['Servers'][$i]['AllowNoPassword'] = TRUE; // it should be placed before the following line $i++; } // other configuration options $cf...

Add Password To Existing Zip File With 7zip

Answer : By nature if you want the file to be encrypted, it needs to be unpacked and repacked, since the whole archive needs to be encrypted with the password. Would it work for you to zip the zip file? Use no/low compression and encrypt the original zip file. Its a lot quicker than repacking the original files.

Can I Remove A RAR File's (known) Password Without Recompressing The Archive?

Answer : Out of the box, no, you can not. Version 3 of the RAR file format (implemented first in WinRAR 2.9) encrypts the actual data itself, as well as the file headers (if requested) using AES-128 encryption. With just WinRAR, it is impossible to simply "remove" the password from an archive, since the data itself is encrypted with the password. You could make a quick batchfile implementing a "remove password" feature, which could simply unrar the archive, and then re-compress the files without a password. Technically , the data is compressed before being encrypted. This indicates that, given enough knowledge of the RAR file format itself, one could create a tool to AES-decrypt the datastream of the compressed files, and then save it into a new RAR archive. It should be noted, however, that this requires extensive knowledge of the file format itself. Given the number of open-source tools that support password-protected RAR files (e.g. unar), one c...

AWallet Password Manager

Answer : aWallet specifically: don't use it. The creator obviously doesn't know what they are doing. I'll just pick out one concern (there are several that will probably be more obvious to People Smarter Than Me): it could encrypt your database in ECB mode (sometimes, but not always). ECB mode is notably not secure because the same plaintext always encrypts to the same cypher text. Therefore, ECB mode "does not hide data patterns well...it doesn't provide serious message confidentiality, and it is not recommended for use in cryptographic protocols at all". Password managers in general: use one. But pick a well-known one with good reputation like 1Password, LastPass, KeePass, Dashlane, etc. Or at least use one created or recommended by a well-known security company or security researcher if you don't know where else to look. A good password manager with competent encryption ( not aWallet apparently) is perfectly safe to keep on cloud storage, provid...
