a little background: im a merchant and accept bitcoin payments. the addresses are created with an electrum MPK. I want to give my customers a possibility to doublecheck if the address where he is about to send his payments to, is really from my wallet. In case my webshop gets compromised a hacker might change the displayed btc addresses. fairly unlikely, but if the customer wants to be 100% sure he could see my pgp signed MPK, and check if the btc address really belongs.

It would be sufficiant if the customer can enter the mpk somewhere and create addresses, so he could check if the btcaddress apears in the list. I have seen php scripts creating addresses from the mpk, but no website where you can just enter the MPK and display the correspondant addresses. I could implement this feature myself into our shop, but that wouldnt give any extra safety, it has to be a third party like a different website from ours to be sure that the output is real.

Is there an electrum command where you can display btc addresses from an MPK of somebody elses wallet?

would be happy if anybody has an idea how i could give my customers a possibility to doublecheck the given addresses somehow, for their and my own safety.

Hey There,

Is there a way to check if a BTC address belongs to a certain wallet? Like for example i know the electrum Master Public Key of the recipients wallet and want to check if the BTC address I have is really from his wallet?

thx

PP

if anybody came via google or so and faces the same problem. The previous steps actually did fix the problem, i just had to run "pecl install gnupg" again and it works fine finally. Thanks seoincorporation great job.

You sure you dont want to just connect via teamviewer and try a little yourself? We can continue like this but i figured for it to be more easy

I found this thread with somebody who has the same problem:

https://forums.cpanel.net/f34/installing-gnupg-php-module-204921.html

hmm this is what i was trying in the beginning. i installed all dependencies, but get an error when trying to run pecl install gnupg

i transferred you 25$ for a start to thank for your efforts so far. I really hope we can get this thing running.

thats exactly what I have tried before unfortunately. The /etc/php.d/gnupg.ini is somewhat mentioned in the phpinfo() screen but it didnt load the extension. I also have put the line in php.ini but no changes

[root@server ~]#

seems to be installed... the problem is that I dont get it integrated in PHP

ah ok i think we are almost there then. I still cant call it via PHP, probably because the extension isnt loaded.

on the last linux server where it all worked i used this command i think:

echo extension=gnupg.so > /etc/php5/conf.d/gnupg.ini

on my new server the directory seems to be here:

/etc/php.d/

so i created the ini there, but it isnt loaded when i do phpinfo(), it only appears here:

Additional .ini files parsed
/etc/php.d/curl.ini, /etc/php.d/fileinfo.ini, /etc/php.d/gd.ini, /etc/php.d/gnupg.ini, /etc/php.d/json.ini, /etc/php.d/mbstring.ini, /etc/php.d/mcrypt.ini, /etc/php.d/mysql.ini, /etc/php.d/mysqli.ini, /etc/php.d/pdo.ini, /etc/php.d/pdo_mysql.ini, /etc/php.d/pdo_sqlite.ini, /etc/php.d/phar.ini, /etc/php.d/sqlite3.ini, /etc/php.d/zip.ini

the gmt is loaded file but no gpg in phpinfo()

Thanks for your help really appreciate it,

any ideas?

Hello,

I am trying to setup the openpgp and gmp package on a centos server. Apache and PHP are already running, and I have some scripts that automatically encrypt a message with pgp, so I need the required packages installed. I already installed everything successfully on 2 other servers (debian and ubuntu) but I dont get it to work on the centos server. need to say that I am a linux newb and its probably not big of a deal for somebody who has more experience with installing packages and their dependencies on a linux machine.

This is how I thought we do this. I prepare the ssh connection to the server and all the infos i got including the tutorial I used to set it up on the other servers. You connect via teamviewer to my PC and we text through notepad or something while you try your best in the putty connection.

Happy to hear from somebody,

PP
