Re: [PHP] Encryption/decryption of PHP data
if you want client to send encrypted form to server. then it must be done using some kind of client side script (javascript?). i don't think it is reliable. why not just use https protocol. all data between client and server will be encrypted.

The project in which I am working is definitely selling the software and we have no intention of distributing the source code with it. So that leaves GnuPG out. Is there any other PHP public key-private key implementation which I can use which either I will pay for or does not use the Gnu Public license ? -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Why would it not be reliable if I were using a public-key/private-key encryption library which works both with PHP and C++ ? why not just use https protocol. all data between client and server will be encrypted. The data must be encrypted/decrypted going both ways between the client and the server. Does using https automatically do that ? If it does that would be great.

Re: [PHP] Encryption/decryption of PHP data
As I understand it: You can LINK your commercial binary with GPL binaries, and keep closed source. You cannot co-mingle the two C source codes together and keep it closed. I am fairly certain you can find commercial C++ offerings to generate PGP key pairs, instead of using the GnuPG OSS alternative... -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
