SHA256-CRYPT / SHA512-CRYPT in node.js



I use dovecot as my mail transfer agent and I aim to use the strongest password scheme which is supported by my system: SHA512-CRYPT or SHA256-CRYPT (BLF-CRYPT doesn't work).



For my own written webinterface I look for a function or library in node.js for hashing a password (with SHA***-CRYPT).

You may consider checking: https://github.com/mvo5/sha512crypt-node which contains a implementation for sha512crypt in JS. Its very new but passes the testvectors from the glibc reference implementation.



Check out my fork of shacrypt - a Node.js addon that supports SHA-256 crypt and SHA-512 crypt password hashing.



I extended it to:



Support asynchronous operation where computation is performed in Node.js's libuv thread pool, so it won't block the event loop.



Allow the module to be built under Windows



You will need to have C++ build tools installed on your system to successfully install the package. If you are running under Windows, you can download Microsoft's Build Tools for Visual Studio 2017.

Have you seen this page:
cryto.createHash sha512 with hexDigest input type



You can use crypto.createHash function, but why SHA512? Are you sure you need it for your website?





SHA512 != SHA512-CRYPT (includes automatically rounds and salting)

Have not seen any public implemention of this algorithm in nodejs

Firebase Auth - with Email and Password - Check user already registered

Clash Royale CLAN TAG #URR8PPP Firebase Auth - with Email and Password - Check user already registered I want to check when a user attempts to signup with createUserWithEmailAndPassword() in Firebase user Authentication method, this user is already registered with my app. createUserWithEmailAndPassword() 8 Answers 8 To detect whether a user with that email address already exists, you can detect when the call to createUserWithEmailAndPassword () fails with auth/email-already-in-use . I see that @Srinivasan just posted an answer for this. createUserWithEmailAndPassword () auth/email-already-in-use Alternatively, you can detect that an email address is already used by calling fetchSignInMethodsForEmail() (previous called fetchProvidersForEmail() ). fetchSignInMethodsForEmail() fetchProvidersForEmail() When the user trying to create an user with same email address, the task response will be "Response: The email address is already in use by another account." mFirebas

Clash Royale CLAN TAG #URR8PPP Dynamically update html content plain JS So I have a script bound in my index.html, which literally has to fetch an array of jsons from an api, then dynamically update my page when get response. But as a result I'm getting an as the only update of my page. here is my script fetch(url) .then((resp) => resp.json()) .then((resp) => resp.results.forEach(item => fetch(item.url) .then((response)=> response.json()) .then((response) => pokeArr.push(response)) .catch(console.log) ) ).catch(console.log) const filler = () => if(!pokeArr) return 0 pokeArr.map((i,j)=> return `<tr>$i.name</tr>` ) const pokeindex = () => document.getElementById('a').appendChild(document.createElement(filler())) pokeindex() When I'm consoling it, I can see in the console all the responses I get, so I'm at least doing the fetching part right. What's parberakan ? What's pokeArr ? – T.J. Crowder Aug 8 at 12

How to determine optimal route across keyboard

Clash Royale CLAN TAG #URR8PPP How to determine optimal route across keyboard I'm trying to automate the typing process in a video game. Players are given an on-screen QWERTY keyboard layout that they can navigate with the control stick (up, down, left, right) in order to select a letter to type. I was wondering if there was a module for Python (or some other resource I could explore) that would help my program find a path across the keyboard as it types each letter in a given message. In other words, if the first letter typed was "A" and the next letter was "B", the module would know that the program should move 1 space down on the keyboard and 4 spaces to the right. Currently, I have the program resetting to the "G" key after each letter is typed (allowing me to use fixed-directions as the program parses each character in the desired message). As you can imagine, this is quite inefficient and defeats the purpose of automating the typing in the fir
