SSL 2.0 (Secure Socket Layer) was originally released in 1995 and was soon replaced by SSL 3.0 in 1996. The protocols are quite old now, and over the years security flaws have been found in the protocols. Which meant that it was insecure and needed to be replaced.
There was a SSL 1.0 prior to 1995, however it was never released because TLS 1.0 was released in 1999, and was intended to be a replacement for SSL. Because TLS 1.o was largely based on the now insecure SSL 3 protocol, and TLS 1.1 is now insecure and vulnerable to attack as well. The most notable was the POODLE attack.
There are now newer versions of TLS (1.2 and 1.3) which are more secure and considered safe to use.
Why can’t VentraIP Australia support SSL or earlier versions of TLS?
VentraIP Australia implements PCI DSS security standards, which requires us to disable support for older versions of SSL and TLS. The reason behind this, is the older versions are very old and insecure now, and cannot be used for the transmission of private or confidential information.
Our intentions are entirely positive here, we want to provide the best quality and most secure services possible. This includes finding the best balance between security and compatibility that we can.
The versions that we no longer support are SSL 1, SSL 2, SSL 3, TLS 1.0 and TLS 1.1. These versions are 20+ years old, and have been replaced by some more modern encryption protocols and standards.
Rest assured, most modern computers, devices and operating systems already support the newer versions of the TLS encryption protocols (versions 1.2 and 1.3). It’s only older operating systems and software that don’t support the new encryption.
