How to Extract Bitcoin Addresses ??

[apoorvlathey]

I want a javascript (.js) that can find the Valid Bitcoin Addresses from a piece of text.
This might help :

https://github.com/achow101/BitcointalkAccountPricer/blob/master/src/com/achow101/bctalkaccountpricer/server/Address.java

It is the GitHub directory of http://www.bctalkaccountpricer.info . This java file does the same task that i want.
The only problem is that i want that it should be a .js script. Can anyone help me in achieving this ?

Are you familiar with regular expressions? If so, you can find the solution on this[1] post on Stackoverflow. I used it myself some time ago and it worked fine.

You can use https://github.com/trapp/brainwallet to understand how address generation works,  but be aware that it is vulnerable that's why original Brainwallet website was shut down.
For production version use bip32 based https://bip32jp.github.io/english/.
