bcrypt.compare takes 3 parameters; passwordToCheck, passwordHash, and a callback, respectively. (Check the documentation for examples) This error means one or both of the first 2 parameters are either null or undefined. Therefore, make sure both of them are passed correctly. (Not as null or undefined)
After running bundle install to install bcrypt, just restart the rails server. That should help your application to reload and pick up the newly installed bcrypt dependency.
Peppers: yes you are correct. There is not much additional security achieved with a pepper if you are using salt. Stretches: 12 is reasonable, however bcrypt only ensures a constant time. You should consider using the newer scrypt as it allows you to specify both a constant time and the amount of memory to use. … Read more
await dosent wait for bcrypt.hash because bcrypt.hash does not return a promise. Use the following method, which wraps bcrypt in a promise in order to use await. async function hashPassword (user) { const password = user.password const saltRounds = 10; const hashedPassword = await new Promise((resolve, reject) => { bcrypt.hash(password, saltRounds, function(err, hash) { if … Read more
I had the same problem installing under OSX 10.7.3. When installing the gem, my error message was: Building native extensions. This could take a while… ERROR: Error installing bcrypt-ruby: ERROR: Failed to build gem native extension. creating Makefile make compiling bcrypt_ext.c make: /usr/bin/gcc-4.2: No such file or directory make: *** [bcrypt_ext.o] Error 1 Looks like … Read more
I make the assumption that you use Python 3. With Python 3, strings are, by default, unicode strings. If you call the bcrypt.checkpw() function with unicode values: import bcrypt password = “seCr3t” # unicode string hashed_password = “hashed_seCr3t” # unicode string bcrypt.checkpw(password, hashed_password) You’ll get this exception Traceback (most recent call last): … TypeError: Unicode-objects must be … Read more
Add this in you docker file before npm install: RUN apk add –update python make g++\ && rm -rf /var/cache/apk/* If you’re working with Python 3, remember to use python3 instead of python.
Check out https://npmjs.org/package/bcryptjs, it’s fully compatible with bcrypt just without the dependencies. Or https://npmjs.org/package/simplecrypt if you don’t want the crypto boilerplate and just need to encrypt and decrypt strings.
