I Just Released My Personal Password Manager App — CyberSafe

Duc Nguyen Van — Mon, 09 Jun 2025 17:49:57 +0000

Hello everyone!

I’m excited to share that CyberSafe — a fully offline password manager app I developed personally — has just been published on Google Play!

This project has been a labor of love for me. I wanted to build a secure app that allows users to safely store passwords and sensitive information completely offline with strong AES-256 encryption. CyberSafe requires no account, no cloud sync, and fully respects user privacy.

The app features a clean and intuitive interface optimized for both phones and tablets. Some key features include:

Manage passwords, notes, and 2FA (TOTP) codes
Powerful password generator and smart security check
Secure backup and restore stored locally on your device
No ads, no tracking, no data collection

I would be grateful for your support, feedback, and congratulations as I continue to improve and grow CyberSafe.

Thank you all for following along and being part of this journey!

I'm having trouble merging arrays in reactjs

Duc Nguyen Van — Tue, 06 Dec 2022 10:48:39 +0000

i'm doing a recursive array merge into an array but it's not working

this is current data

let currentData = [
   {
     "id":1,
     "content":"Comment 1"
     "answers":[
       {
       "id":3,
       "content":"Comment 3"
       "answers":[ 
         {
         "id":4,
         "content":"Comment 4",
         "answers":[]
         },
         {
         "id":5,
         "content":"Comment 5",
         "answers":[]
         }]
       }
     ]
   }
   {
     "id":2,
     "contents":"Comment 2"
     "answers":[
       {
          "id"6,
          "content":"Comment 6",
          "answers":[]
       }
     ]
   }
 ]

I want like this

[
     {
          "id": 1,
          "content": "Comment 1"
     },
     {
          "id": 2,
          "content": "comment 2"
     },
     {
          "id:": 3,
          "content": "comment 3"
     },...
]

I tried using this function but it doesn't work

 const [replyList, setReplyList] = useState([])
 useEffect(()=>{
    handleMerge(currentData)
  },[])
 const handleMerge = (reply) => {
    if (reply.length == 0) {
      return
   }
    for (let i = 0; i < reply.length; i++) {
        setReplyList([...replyList,reply[i]])
        handleMerge(reply[i].reply)
      }
    }
