海外TECH	DEV Community	What is Bcrypt. How to use it to hash passwords	https://dev.to/documatic/what-is-bcrypt-how-to-use-it-to-hash-passwords-5c0g	What is Bcrypt How to use it to hash passwordsThe bcrypt npm package is a JavaScript implementation of the bcrypt password hashing function that allows you to easily create a hash out of a password string Unlike encryption which you can decode to get back the original password hashing is a one way function that can t be reversed once done When the user submits a password the password will be hashed and your JavaScript application needs to store the hash in the database Later when the user wants to authenticate his or her account you need to compare the password input with the hash stored in your database to see if it matches The bcrypt library makes the process easy by providing you with methods to hash and compare passwords To start using the library you need to install it with your package manager npm install bcrypt oryarn add bcrypt Then include the module to your JavaScript code with require const bcrypt require bcrypt Creating a password hash with bcryptTo generate a password using the bycrypt module you need to call on the hash method which accepts the following three parameters The password string that you wish to hashThe number of rounds to secure the hash The number commonly ranges from to The callback function to execute when the hash process is finished passing along the error message and the hash resultHere s an example of bcrypt hash processing the password string generic const bcrypt require bcrypt bcrypt hash generic function err hash console log hash TODO Store the hash in your password DB Or you can use the synchronous method equivalent called hashSync const bcrypt require bcrypt const myPlaintextPassword generic const hash bcrypt hashSync myPlaintextPassword console log hash Generating salt for the hashA hashing function requires you to add salt into the process A salt is simply a random data that s used as an additional input to the hashing function to safeguard your password The random string from the salt makes the hash unpredictable In the code examples above the salt is auto generated by bcrypt module but you can actually generate the salt first before hashing the password To generate a salt you can use the genSalt method from the module const bcrypt require bcrypt bcrypt genSalt function err salt console log salt the random salt string Once you have the salt you can pass it to the hash method as follows const bcrypt require bcrypt bcrypt genSalt function err salt bcrypt hash generic salt function err hash console log hash Store hash in your password DB There s also a synchronous equivalent for the method called genSaltSync const salt bcrypt genSaltSync const hash bcrypt hashSync generic salt Note that there s no differences on the resulting hash whether you generate a salt separately or automatically but the CPU usage may be lowered when you separate the salt generation and the hash process You should test if your NodeJS server can handle auto generating the salt and hash first before separating them A note on the salt round numberThe salt generation for your hash function can range from a few seconds to many days depending on how many rounds you passed The bcrypt module will go through rounds to generate the salt to give you a secure hash According to the documentation here s the amount of time to process the salt generation on a GHz core computer rounds hashes secrounds hashes secrounds hashes secrounds hashes secrounds hashes secrounds sec hashrounds sec hashrounds sec hashrounds hour hashrounds days hashThe number is just an estimation so you may want to test the highest rounds with the fastest generation time that your server can support Verifying a password with bcryptOnce you saved the hash to the database you can compare the user s plain text input with the stored hash using the compare method The compare method accepts three parameters The plain string password for comparisonThe hash string created earlierAnd the callback function once the comparison process is finishedThe method will pass the error err object and the boolean value result telling you whether the comparison matches or not Here s an example of the compare method in action const bcrypt require bcrypt bcrypt hash generic function err hash console log hash The hash returned continue to compare bcrypt compare generic hash function err result console log generic result generic true bcrypt compare falsy hash function err result console log falsy result falsy false The module also provides the synchronous method compareSync for you to use const bcrypt require bcrypt const myPlaintextPassword generic const hash bcrypt hashSync myPlaintextPassword const result bcrypt compareSync myPlaintextPassword hash console log result trueAfter the comparison is finished you need to provide the right authentication code according to the returned result Using promise or async await instead of callback functionFinally bcrypt module also supports the use of promise and async await code style so you can use them instead of callbacks to make your code cleaner Here s an example of using promises in the hash process const bcrypt require bcrypt bcrypt hash generic then hash gt return bcrypt compare generic hash then result gt console log generic result generic true catch err gt console log err And another example using the async await style const bcrypt require bcrypt async function passwordHashTest password const hash await bcrypt hash password const result await bcrypt compare password hash console log result true passwordHashTest generic test the async functionAnd that s how the bcrypt module in NodeJS works If you
