bcrypt

问题 The question is the same title, Where $2x$ is used in BCrypt? The following scenario is right? We have a set of passwords that hashed with $2a$ prefix already, when the Server PHP version was earlier 5.3.7 . Now we upgraded the PHP to 5.3.7+ , now we must firstly verify previous passwords with $2x$ algorithm then rehash the password with $2y$ prefix. That's right? 回答1: Note to wikipedia editors : Content in this answer is in the public domain; i know because i wrote it. I wrote it first for

问题 I'm trying to install bcrypt on CentOS server but I got the following error: info postuninstall bcrypt@0.5.0 ERR! bcrypt@0.5.0 install: `make build` ERR! `sh "-c" "make build"` failed with 2 ERR!

Tell the author that this fails on your system: ERR! make build ERR! You can get their info via: ERR! npm owner ls bcrypt ERR! There is likely additional logging

问题 bcrypt.compare() always comes back false with this code in the user model. This is with bcrypt-nodejs. User.pre('save', function (callback) { this.password = bcrypt.hashSync(this.password, bcrypt.genSaltSync(10)) this.token = jwt.sign(this.email, process.env.JWT_SECRET) callback() }) User.methods.verifyPassword = function ( password ) { const self = this return Q.Promise( (resolve, reject) => { bcrypt.compare( password, self.password, (error, isMatch) => { if (error) reject( new Error("Error

问题 I am building a registration system for my web application wherein users provide a username and a password. This data is stored in a postgresql database. I am using bcrypt to generate a salted hash of the user entered password as follows import bcrypt hashed = bcrypt.hashpw(PasswordFromWebForm.encode('UTF-8'), bcrypt.gensalt()) This creates a salted password that looks something like this - b'$2b$12$GskbcRCMFHGuXumrNt3FLO' I am storing this value in a postgresql database. Next, when a user

问题 i got a problem with bcrypt on node.js -> the bcrypt compare method returns false while comparing the passwords from a mongoDB and a user entry. I have no idea why and i tried to debug it since 3 days but i really need some extern help... UserShema: var userSchema = new Schema({ name: { type: String, required: true }, password: { type: String, required: true } }); hash and salt: userSchema.pre('save', function (next) { var user = this; if (this.isModified('password') || this.isNew) { bcrypt

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed last year . I used NuGet to get the BCrypt library and it's installed properly. Now I'd like to read about it and how to use it, yet I can't seem to find any documentation. Even searching for the libraries namespace yielded no results: DevOne.Security.Cryptography.BCrypt Any suggestions on where to find some examples, or even

问题 The question relates to passwords users input while creating an account, for example, to register with some web-page. I have encountered web-sites that require users to input lower and upper-case letters with numbers and special characters... some web-sites go to an extreme, requesting users to follow strict guidelines. Is all of that really necessary? What are some of the simplest and minimal rules to follow creating a safe user password? At which point does it become a placebo? 回答1: Complex

问题 I am working through the Ruby on Rails Tutorial by Michael Hartl and have generated an interesting dilemma. I will have done something wrong, so I need your help finding the issue. The issue surrounds the validation of a password property within a User model. The initial validation of this property was: validates :password, presence: true, confirmation: true, length: { minimum: 6 } This requires a minimum length of the password and is designed to satisfy the situation where a new user creates

问题 There is no straight forward bCrypt ( http://codahale.com/how-to-safely-store-a-password/) implementation in Objective-C, and while there are C code that does accomplish this, it's specifically for x86 processors, relying on BSD libraries. I'm building an iOS app which shares the same password hashes as corresponding Online (.NET and HTML5+Javascript) applications. I'm not quite where I ought to be, where I can read the awfully simplistic Java code ( http://www.mindrot.org/projects/jBCrypt/)

问题 After looking into a bug in the original jBCrypt v0.1 C# port: BCrypt.net (Related Question). I decided to compare the new jBCrypt code against the old C# port to look for discrepancies and potential issues like the related question's bug. Here is what I've found: // original java (jBCrypt v0.3): private static int streamtoword(byte data[], int offp[]) { int i; int word = 0; int off = offp[0]; for (i = 0; i < 4; i++) { word = (word << 8) | (data[off] & 0xff); off = (off + 1) % data.length; }
