Telnet vs TLS

Developers should learn Telnet for legacy system maintenance, network troubleshooting, and understanding foundational remote access concepts, as it is still used in some embedded systems, routers, and older infrastructure meets developers should learn and use tls to secure data transmission in applications, especially for web services, apis, and client-server communications where sensitive information like passwords or financial data is exchanged. Here's our take.

Telnet

Nice Pick

Developers should learn Telnet for legacy system maintenance, network troubleshooting, and understanding foundational remote access concepts, as it is still used in some embedded systems, routers, and older infrastructure

Pros

• It is valuable for testing network services (e
• Related to: ssh, tcp-ip

Cons

• Specific tradeoffs depend on your use case

TLS

Developers should learn and use TLS to secure data transmission in applications, especially for web services, APIs, and client-server communications where sensitive information like passwords or financial data is exchanged

Pros

• It is essential for implementing HTTPS in web development, protecting against eavesdropping and man-in-the-middle attacks, and is required for compliance with security standards like PCI DSS
• Related to: https, cryptography

Cons

• Specific tradeoffs depend on your use case

The Verdict

These tools serve different purposes. Telnet is a protocol while TLS is a concept. We picked Telnet based on overall popularity, but your choice depends on what you're building.

The Bottom Line

Telnet wins

Based on overall popularity. Telnet is more widely used, but TLS excels in its own space.
