SSH vs TLS
SSH (Secure Shell) and TLS (Transport Layer Security) both come up in technology conversations and get confused. Here's the plain-English difference, side by side, so you can use each one with confidence.
The key difference: SSH refers to secure shell, while TLS refers to transport layer security — they describe different things even when they show up in the same sentence.
SSH — Secure Shell
An encrypted protocol for accessing and operating remote servers. Still the backbone of how engineers touch production — which is why SSH key hygiene is non-negotiable.
TLS — Transport Layer Security
The cryptographic protocol that encrypts data in transit on the modern web. The "S" in HTTPS — and the bare minimum any serious product ships with.
When to use SSH
Reach for "SSH" when the conversation is specifically about secure shell. An encrypted protocol for accessing and operating remote servers. Still the backbone of how engineers touch production — which is why SSH key hygiene is non-negotiable.
When to use TLS
Reach for "TLS" when the conversation is specifically about transport layer security. The cryptographic protocol that encrypts data in transit on the modern web. The "S" in HTTPS — and the bare minimum any serious product ships with.
FAQs
What is the difference between SSH and TLS?
SSH stands for Secure Shell — An encrypted protocol for accessing and operating remote servers. Still the backbone of how engineers touch production — which is why SSH key hygiene is non-negotiable. TLS stands for Transport Layer Security — The cryptographic protocol that encrypts data in transit on the modern web. The "S" in HTTPS — and the bare minimum any serious product ships with.
Are SSH and TLS the same thing?
No. They're often used in the same conversation because they're related, but they describe different concepts. SSH = Secure Shell. TLS = Transport Layer Security.
When should I use SSH vs TLS?
Use SSH when you're specifically referring to secure shell. Use TLS when the topic is transport layer security.
