CAcert.org is a community driven, Certificate Authority that issues certificates to the public at large for free.
CAcert's goal is to promote awareness and education on computer security through the use of encryption, specifically with the X.509 family of standards. We have compiled a document base that has helpful hints and tips on setting up encryption with common software, and general information about Public Key Infrastructures (PKI).
For the enthusiast looking to dip their toe in the water, we have an easy way of obtaining certificates you can use with your email program. You can use these not only to encrypt, but to prove to your friends and family that your email really does come from you.
For administrators looking to protect the services they offer, we provide host and wild card certificates which you can issue almost immediately. Not only can you use these to protect websites, but also POP3, SMTP and IMAP connections, to list but a few. Unlike other certificate authorities, we don't limit the strength of the certificates, or the use of wild card certificates. Everyone should have the right to security and to protect their privacy, not just those looking to run ecommerce sites.
If you're extremely serious about encryption, you can join CAcert's Assurance Programme and Web of Trust. This allows you to have your identity verified to obtain added benefits, including longer length certificates and the ability to include your name on email certificates.
CAcert Inc. is a non-profit association, incorporated in New South Wales Australia.
Kiran Kuppa on 29 Jul 13"Google engineers are experimenting with new ways to replace user passwords, including a tiny YubiKey cryptographic card that would automatically log people into Gmail, according to a report published Friday. In the future, engineers at the search giant hope to find even easier ways for people to log in not just to Google properties, but to sites across the Web. They envision a single smartphone or smartcard device that would act like a house or car key, allowing people access to all the services they consume online. They see people authenticating with a single device and then using it everywhere."
