Getting Started

Install this module.

npm install sails-service-hash

Then require it in your service and create Hash instance.

// api/services/HashService.js
import HashService from 'sails-service-hash';
 
export default HashService('bcrypt');
 
// api/controllers/HashController.js
export default {
  compare: function(req, res) {
    let myPasswordInHash = HashService.hashSync('MY_PASSWORD');
    let isCorrectPassword = HashService.compareSync('MY_PASSWORD', myPasswordInHash);
    res.ok(isCorrectPassword);
  }
};

API

Each of Hash instances has 4 methods:

hash(data, config)

data - Plain data that you want to hash.

config - Additional configuration for override pre-defined config.

Hash your data and returns Promise.

hashSync(data, config)

data - Plain data that you want to hash.

config - Additional configuration for override pre-defined config.

Hash your data in sync mode and returns hash.

compare(plainData, hash, config)

plainData - Plain data that you want to compare with.

hash - Hash that was got from hash methods.

config - Additional configuration for override pre-defined config.

Compare plainData with hash and returns Promise.

compareSync(plainData, hash, config)

plainData - Plain data that you want to compare with.

hash - Hash that was got from hash methods.

config - Additional configuration for override pre-defined config.

Compare plainData with hash and returns Boolean.

Examples

BCryptHash

let bcrypt = HashService('bcrypt', {
  saltLength: 10 // Optional argument if you want to specify rounds for of auto-generated salt
});
 
bcrypt.hash('MY_PASSWORD').then(hash => {
  bcrypt.compare('MY_PASSWORD', hash).then(console.log.bind(console));
});
 
let hash = bcrypt.hashSync('MY_PASSWORD');
let isEqual = bcrypt.compareSync('MY_PASSWORD', hash);
