Understanding TLS Versions

Transport Layer Security (TLS) is a protocol that ensures privacy between communicating applications and users on the internet. TLS has evolved over the years, with each version bringing enhancements and security improvements. As organizations upgrade their systems, it’s critical to understand the compatibility of these TLS versions with various data access technologies such as SQL OLE DB.

The following are the main TLS versions and their characteristics:

  • TLS 1.0: Introduced in 1999, it is considered insecure and has been deprecated.
  • TLS 1.1: Released in 2006, it improved upon TLS 1.0 but is also considered weak against modern attacks.
  • TLS 1.2: Launched in 2008, it offers strong security features and is widely used.
  • TLS 1.3: The latest version, finalized in 2018, simplifies the handshake process and enhances security.

I didn’t start out in tech with a clear path. Like many self taught developers, I pieced together my skills from late-night sessions, half documented errors, and an internet full of conflicting advice. What stuck with me wasn’t just the code it was how hard it was to find clear, grounded explanations for everyday problems. That’s the gap I set out to close.

Freak Learn is where I unpack the kind of problems most of us Google at 2 a.m. not just the “how,” but the “why.” Whether it's container errors, OS quirks, broken queries, or code that makes no sense until it suddenly does I try to explain it like a real person would, without the jargon or ego.
