Is it possible to fake SSL certificate?

Any fake certificate you create will be a self-signed certificate. In order to avoid warnings, you need a certificate signed by a certificate authority that the browser trusts, such as VeriSign. These companies will hopefully make sure that you actually own the domain for the certificate they’re signing.

Is self-signed false?

With self-signed SSL they cannot simply listen in, but now must fake your site, potentially alter DNS to do a man it the middle (MITM) attack. This is still a threat, but significantly more difficult for them to accomplish.

Why are self-signed certificates not trusted?

Organizations may ban the use of self-signed certificates for several reasons: It is trivially easy to generate a certificate’s key pair without reasonable entropy, to fail protect the private key of the key pair appropriately to its use, to poorly validate the certificate when used, and to misuse a self-signed …

Which is better, a self signed SSL certificate or a trusted CA certificate?

While Self-Signed certificates do offer encryption, they offer no authentication and that’s going to be a problem with the browsers. Trusted CA Signed SSL Certificates, on the other hand, do offer authentication and that, in turn, allows them to avoid those pesky browser warnings and work as an SSL Certificate should.

How can you tell if a SSL certificate is valid?

When you get an SSL certificate from a server, you get the server’s public key, and a signature from a CA saying that it’s valid (along with some other info). If you know and trust that CA, you can check the signature and determine if it’s valid.
