Are you new to CAcert?

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 by providing cryptographic certificates. These certificates can be used to digitally sign and encrypt email, authenticate and authorize users connecting to websites and secure data transmission over the internet. Any application that supports the Secure Socket Layer Protocol (SSL or TLS) can make use of certificates signed by CAcert, as can any application that uses X.509 certificates, e.g. for encryption or code signing and document signatures.

If you want to have free certificates issued to you, join the CAcert Community .

If you want to use certificates issued by CAcert, read the CAcert Root Distribution License .This license applies to using the CAcert root keys .

Thank you so much!

Our treasurer tries to owe donations personally. Now we have learned from our German support association secure-U e.V. that many European CAcert supporters have made use of the possibility to transfer donations directly to their bank account. Also a big thank you to all these donors, even if we don’t know them by name!

Herzlichen Dank!

Unser Kassier bemüht sich, Spenden jeweils persönlich zu verdanken. Nun haben wir von unserem deutschen Unterstützungsverein secure-U e.V. erfahren, dass sehr viele europäische CAcert-Unterstützer von der Möglichkeit Gebrauch gemacht haben, Spenden direkt auf deren Bankkonto zu überweisen. Auch all diesen Spendern ein herzliches Dankeschön, auch wenn wir sie nicht namentlich kennen!
