LessPass
Stateless Password Manager Stop wasting your time synchronizing your encrypted vault. Remember one master password to access your passwords, anywhere, anytime, from any device. No sync needed. How does it work? Compute your password offline LessPass computes a unique password using a site, login, and a master password. You don't need to sync a password vault across every device or to the cloud, be
10 Ways to Generate a Random Password from the Command Line - How-To Geek
There are many reasons you would want to restore a database from a backup file... But you should also test this on a test server just to make sure that your database backups are working correctly. Here's the syntax: mysql -h hostname -u username -pthepassword databasename < dumpfile.sql Here's an example: mysql -h localhost -u root -p72aDufi8 db01 < thedumpfile.sql
yescrypt: password hashing scalable beyond bcrypt and scrypt (PHDays 2014)
Follow @Openwall on Twitter for new release announcements and other news yescrypt: password hashing scalable beyond bcrypt and scrypt These are the slides on yescrypt that we used at PHDays 2014. In a sense, this presentation is a continuation of Password security: past, present, future (PHDays 2012, Passwords^12), Password hashing at scale (YaC 2012), New developments in password hashing: ROM-por
1Password hashcat strong master passwords | 1Password
You may have heard some news going around about hashcat, a password cracking tool, that recently increased its ability to guess Master Passwords for 1Password data files. It’s an impressive achievement for hashcat, and it is important to understand what this does and doesn’t mean for 1Password. What you need to know1Password has not been “cracked” The existence of a new cracking tool (actually the

Don't use bcrypt
Hi, I'm Tony Arcieri. You may remember me from such software projects as Celluloid, Reia, and Cool.io... If you're already using bcrypt, relax, you're fine, probably. However, if you're looking for a key derivation function (or in bcrypt's case, password encryption function) for a new project, bcrypt is probably not the best one you can pick. In fact, there are two algorithms which are each better
How to securely hash passwords?
Note: This answer was written in 2013. Many things have changed in the following years, which means that this answer should primarily be seen as how best practices used to be in 2013. The Theory We need to hash passwords as a second line of defence. A server which can authenticate users necessarily contains, somewhere in its entrails, some data which can be used to validate a password. A very simp
Storing Passwords Securely
Storing Passwords Securely June 6, 2012 Time and time again you hear about a company having all of their users’ passwords, or “password hashes”, compromised, and often there’s a press response including one or more prominent security researchers demonstrating how 1,000 users had the password “batman”, and so on. It’s surprising how often this happens considering we’ve had ways to do password authe
Do any security experts recommend bcrypt for password storage?
Bcrypt has the best kind of repute that can be achieved for a cryptographic algorithm: it has been around for quite some time, used quite widely, "attracted attention", and yet remains unbroken to date. Why bcrypt is somewhat better than PBKDF2 If you look at the situation in details, you can actually see some points where bcrypt is better than, say, PBKDF2. Bcrypt is a password hashing function w
Password Hashing Competition
and our recommendation for hashing passwords: Argon2 Password hashing is everywhere, from web services' credentials storage to mobile and desktop authentication or disk encryption systems. Yet there wasn't an established standard to fulfill the needs of modern applications and to best protect against attackers. We started the Password Hashing Competition (PHC) to solve this problem. PHC ran from 2
Java Hashing using MD5, SHA, PBKDF2, Bcrypt and Scrypt
Please remember that once the password hash has been generated, we can not convert the hash back to the original password. Each time a user login into the application, we must generate the password hash again and match it with the hash stored in the database. So, if a user forgets his/her password, we will have to send him a temporary password; or ask him to reset the password. It’s common nowaday
Password strength - Wikipedia
Options menu of the random password generation tool in KeePass. Enabling more character subsets raises the strength of generated passwords a small amount, whereas increasing their length raises the strength a large amount. Password strength is a measure of the effectiveness of a password against guessing or brute-force attacks. In its usual form, it estimates how many trials an attacker who does n
ユーザー認証の手抜き - 方向
Webアプリ作っているといろんな局面でユーザー認証が必要になる局面がある。まじめにつくると果てしなく面倒だし、適当につくるとセキュリティ上問題になるので、要件に応じて適切に手抜きする必要がある。 適当なやつからしっかりしたやつまでなんとなくソートしていくとこんなかんじだと思う。 認証なし IPで弾く Basic認証（ソースコード、設定ファイルにパスワードベタ書き） Basic認証（DBにUserテーブルをつくってパスワードを保存。追加はcliとかで手動） login/logout画面作成。cookieなりmemcacheなりにセッションを保存 webからユーザーを追加できるように password変更機能 OAuth OpenID mailを送ってリンクをクリックさせてメールアドレスの所有確認 メールアドレス変更機能 メールを使ってのパスワードリセット機能 OAuthで作ったアプリへの後か
Pass: The Standard Unix Password Manager
Introducing pass Password management should be simple and follow Unix philosophy. With pass, each password lives inside of a gpg encrypted file whose filename is the title of the website or resource that requires the password. These encrypted files may be organized into meaningful folder hierarchies, copied from computer to computer, and, in general, manipulated using standard command line file ma

Secure Salted Password Hashing - How to do it Properly
Salted Password Hashing - Doing it Right If you're a web developer, you've probably had to make a user account system. The most important aspect of a user account system is how user passwords are protected. User account databases are hacked frequently, so you absolutely must do something to protect your users' passwords if your website is ever breached. The best way to protect passwords is to empl
