1.Open Certification Authority

1.1 http://www.openca.org/openca/docs/online/pr01.html
	Today we support the following things (this is an incomplete list just 
	to give you an impression how complex the subject matter is):
	Public interface, LDAP interface, RA interface,CA interface,
	SCEP, OCSP, IP-filters for interfaces, Passphrase based login
	Certificate based login (incl. smatcards), Role Based Access Control
	flexible certifcate subjects, flexible certificate extensions
	PIN based revocation, digital signature based revocation
	CRL issuing, Warnings for expiring certificates
	support for nearly every (graphical) browser

1.2 http://www.pyca.de/features.html
	pyCA tries to make it easier for people to set up and run a 
	organizational certificate authority which fulfills the need for a 
	fairly secure certification processing. The package also tries to 
	reduce administrative tasks and user's frustration by providing a 
	comfortable web interface to users contacting the certificate authority.

1.3 http://www.hohnstaedt.de/xca.html
	This application is a graphical user interface to OpenSSL, RSA public 
	keys, certificates, signing requests and revokation lists. Xca 
	supports next to the usual PEM and DER format of certificates the 
	import and export of PKCS#12 (aka *.pfx) files and the Certificate 
	import from PKCS#7 files. Certificates can be created by self signing 
	it, by signing it by an other (usually CA) certificate or by signing a 
	PKCS#10 request. Netscape SPKAC is supported since version 0.4.6.
	 The validity dates and x509.v3 extensions can be adjusted to fit 
	ones needs. The use of 	multiple certificates in CA chains is 
	supported and a tree view of the certificates reflects the dependencies.

2. Free certifikates

2.1 https://www.cacert.org/index.php?id=12
	CAcert.org is a community driven, Certificate Authority that issues 
	certificates to the public at large for free.

2.2 http://www.opencerts.com/index.php
	Welcome to OpenCerts, a completely open and free 
	certificate authority (CA) which embraces the foundation of 
	SSL technology: trust. 	We believe that trust should not be 
	leveraged by the companies that pay the most money to get their root 
	certificates into the major browsers, rather, it should be explored 
	through knowledge and understanding of the sites involved in this 
	network.
