### What is a VPN?
|
|
|
|
|
A Virtual Private Network is a private network on the Internet.
|
|
|
|
|
Here, it is made of our customers and our servers acts like routers.
|
|
|
|
|
That means that everything goes through our servers, and you appear anonymous
|
|
|
|
|
on the Internet.
|
|
|
|
|
Because of the strong encryption used, attackers or your ISP cannot log,
|
|
|
|
|
filter, or change anything.
|
|
|
|
|
|
|
|
|
|
### Why should I pay to use it instead of tor?
|
|
|
|
|
Although tor may be free (and extremely good for some usage), tor is also very
|
|
|
|
|
slow and exit nodes can see and intercept your traffic.
|
|
|
|
|
This means that tor is good if you want full anonymity, but not for
|
|
|
|
|
everyday web browsing, or to play an online game. For that, a VPN is perfect.
|
|
|
|
|
|
|
|
|
|
### Do you propose an affiliate program?
|
|
|
|
|
Yes! Share your affiliate link and earn 2 weeks for each referral.
|
|
|
|
|
Invite 24 friends and you get one year of free VPN!
|
|
|
|
|
|
|
|
|
|
### Is P2P allowed?
|
|
|
|
|
On some servers. You can see it in CCVPNGUI and on the configuration download page.
|
|
|
|
|
|
|
|
|
|
### Can I have a static IP address?
|
|
|
|
|
Yes, as each server has its own address. You only have to choose one.
|
|
|
|
|
|
|
|
|
|
### Can I have a dedicated IP address?
|
|
|
|
|
Not at the moment.
|
|
|
|
|
|
|
|
|
|
### Do you monitor or limit bandwidth usage?
|
|
|
|
|
No, every user share each VPN server's connection.
|
|
|
|
|
We always try to have enough bandwidth (at least 20Mbps) available
|
|
|
|
|
for everyone.
|
|
|
|
|
|
|
|
|
|
### Do you censor some websites or protocols?
|
|
|
|
|
No and we will never do it.
|
|
|
|
|
|
|
|
|
|
### Which protocols are supported?
|
|
|
|
|
We only support OpenVPN for now.
|
|
|
|
|
|
|
|
|
|
### Which payment methods are supported?
|
|
|
|
|
We support Paypal, Stripe (credit card) and Bitcoin.

|
|
|
|
|
|
|
|
|
|
### Is it open-source?
|
|
|
|
|
Yes! Our VPN is made with OpenVPN.
|
|
|
|
|
Our servers' config and this website are also open-source and available on our
|
|
|
|
|
[GitHub project](https://github.com/CCrypto/ccvpn/).
|
|
|
|
|
|
|
|
|
|
### Are my data kept secure?
|
|
|
|
|
Yes, the VPN traffic is strongly encrypted and we do not keep any data on the
|
|
|
|
|
VPN servers.
|
|
|
|
|
The website and database are on a different server, in a
|
|
|
|
|
different datacenter.
|
|
|
|
|
|
|
|
|
|
### Will there be more servers/countries available?
|
|
|
|
|
Yes, but we first need money to pay the servers.
|
|
|
|
|
If you would like to have a server somewhere, know a good provider or would
|
|
|
|
|
like to host one, please contact us.

|
### Encryption used
|
|
|
|
|
Authentication uses a 4096 bits RSA key. (3072 bits on oldest servers)
|
|
|
|
|
The current recommended key size considered safe until 2030 is 2048 bits.
|
|
|
|
|
|
|
|
|
|
VPN trafic encryption is performed with the Blowfish cipher using a random
|
|
|
|
|
128 bits key re-generated every 60 minutes, and unique to a VPN connection.
|
|
|
|
|
|
|
|
|
|
Key Exchange uses a 3072 bits Diffie-Hellman parameters.
|
|
|
|
|
A 2048 bits key is considered safe until 2030.
|
|
|
|
|
|
|
|
|
|
### Do you support IPv6?
|
|
|
|
|
Yes, most of our servers are dual stack - they perfectly support IPv4 and IPv6
|
|
|
|
|
at the same time.
|
|
|
|
|
Some are IPv4 only (but we're working with our providers to fix it) and will
|
|
|
|
|
block all IPv6 traffic to make sure your IPv6 address is not leaked.
|
|
|
|
|
|
|
|
|
|
### Do you support PPTP?
|
|
|
|
|
No, PPTP is not supported and will not be supported.
|
|
|
|
|
PPTP is considered insecure and should never be used.

### What do you log?
|
|
|
|
|
We only keep VPN connection IP addresses because of the law.
|
|
|
|
|
We do not keep any data concerning your traffic.
|
|
|
|
|
|
|
|
|
|
### Is it really anonymous?
|
|
|
|
|
Depends of your definition of anonymous.
|
|
|
|
|
It is anonymous, because we will not ask you for your name or verify your
|
|
|
|
|
identity to be able to use the VPN, and we use anonymous payment methods
|
|
|
|
|
like Bitcoin.
|
|
|
|
|
It is anonymous, because no one can directly find out your identity from the other side
|
|
|
|
|
of the VPN.
|
|
|
|
|
However, French authorities can ask us for user data (username, email,
|
|
|
|
|
payments, ...)
|
|
|
|
|
It is traceable in extreme cases and will not hide you from the law.
|
|
|
|
|
|
|
|
|
|
### Will you log traffic or send user data to authorities?
|
|
|
|
|
We won't log your traffic under any condition.
|
|
|
|
|
We may give the little we know about you to authorities
|
|
|
|
|
only if required by the law to keep the service running.
|
|
|
|
|
In this case, we'll try to contact you before doing anything if possible.
