I don't know much about these things, i am new to crypto world
My advice is to familiarize yourself with what you're doing
before sending a large amount to your new address. Test it, test recovery from your backup, test sending, and make sure you understand what you're doing before sending larger amounts to an address.
i used your method and generated a address and its private key, but since i did it offline, what if someone searches the same keywords and gets the same private key or the same address.
My all means:
try it! Try to find the same address again. Or while you're at it, try to find the private key for 1FeexV6bAHb8ybZjqQMjJrcCrHGW9sb6uF (Balance:
). See how long it takes you to find an address that starts with 1FeexV6bAHb8ybZj. On my system, it would take, many billions of years to find. And each additional character makes it 58 times more difficult to find.
Of course you won't find it, but actually trying might help you to understand how secure Bitcoin addresses actually are. Generating it offline is actually a good thing: there's less risk of compromising your private key, and there is no such thing as "generating it online to check if nobody else uses it". That's not needed, as long as your private key is properly (randomly) generated.
Also, how do we get backup phrases for this address or only private key is enough ?
Print it, write it down, stamp it in steel, anything you want works. Note that you don't even need to backup the address itself, it can always be derived from the private key. And when you write down the key,
make sure you can still read it and didn't make mistakes. Try to recover it, you wouldn't be the first to lose funds because of writing mistakes.
"Backup phrases" are just another way to create private keys. Your private key should be randomly generated on it's own, that means there is no "backup phrase". Just don't lose the private key!
Can i receive and send btc freely onto this ?
Yes. But try a small amount first to make sure you do it correctly.
How do we verify signatures into this wallet ?

How to sign a message?!.
Complete noob here, please bear with me
I tried, but this post can't be complete. Welcome to Bitcointalk, you'll find all the information you need here. Just read a lot, stay vigilant, and be very careful who you trust! Scammers are always after your private keys.
