You can check this: https://github.com/zamgo/PHPCoinAddress

Also this script need to be patched for secure working. Look here for more: https://github.com/zamgo/PHPCoinAddress/pull/1

That pull is correct, non-cryptographically secure functions should never be used to generate pub/priv keypairs.

Also, a Bitcoin address can be generated in pretty much ANY language, not just PHP.

It would have been great, if u please shared the secured PHP code...

Everything you need is in that pull request.

Ok... so u mean, I just need to change the random number generator from mt_rand() to openssl_random_pseudo_bytes() ?

Yes. Just copy the changed code in that pull.

thanks, can u plz help me out here => https://bitcointalksearch.org/topic/can-rawtx-be-created-using-php-709974 ?

You're in deep with that, one wrong move with rawtx and you can make a fee that is huge or simply send the coins to some wrong address.

In my specific requirement all the outputs of the address in question will be spent. Hence I'm not bothered about change address or big mining fee. Rather I'm concerned how do I calculate the required mining fee depending on the Tx size.

this tool uses public master key from a deterministic wallet (like electrum) and generates addresses.
i would not run anything else on a server that will be accessible from internet

Yes looks like that in some situations it is not secure enough but my knowledge is too low for better understanding.

Thank you so much... I think it'll serve my purpose. But I did not get the second link. Is not mt_rand() secure enough to generate a random seed ?
