PKI in a Nutshell
A blog by Ronald

This blog briefly describes theoretically how Public Key Infrastructure (PKI) works. It also introduces the key concepts used in PKI. This is done by describing encryption, decryption, hashing, signing, and authentication using mathematical notations.

Researchers from Google and GitGuardian found over 900 TLS certificates used by Fortune 500 firms and governments exposed through leaked private keys on public code platforms like #GitHub.

Why is everyone using #base64 to encode their private SSH keys to store them in masked variables in #GitLab CI?! 🤔

⚠️ GitLab cannot effectively mask your private key in CI logs if you only give it a base64-encoded version of it!

Instead I found a solution that stores the *original* private key format from #OpenSSH in a one-line CI variable and recreates the begin/end markers for a valid OpenSSH identity file with commands inside the CI.
