What is StartSSL?
StartSSL is a certificate authority founded in 2008 that issues free basic SSL certificates for websites. Its certificates utilize 2048-bit encryption to enable HTTPS and the TLS protocol on websites, allowing for secure transmission of data between servers and visitors.
Some key features of StartSSL's free certificates include:
- Domain Validation certificates issued within minutes
- Supports up to 5 domains on one cert
- Valid for 1 year
- Recognized by all major browsers
- Enables green padlock and https in browsers
- Allows use of HSTS security headers
While the basic certificates lack extended validation and some features of paid options, they provide essential transport layer security for small sites and personal projects at no cost. More advanced certificates are available for purchase from StartSSL with more vetting and longer validity periods.
