How deeply does Logs and Telemetry cover Base64?

Shows the credential representation and verification step, but does not explain the encoding algorithm or decoding process.

Base64

As explained in Logs and Telemetry

Base64 encoding represents binary or textual data as ASCII characters using a 64-character alphabet.

Base64 represents binary or textual data with ASCII characters from a 64-character alphabet. In HTTP Basic authentication, the authorization header carries a random-looking Base64 value formed from a username and password separated by a colon. section 5.8

Inspecting Basic authentication

A Fluent Bit HTTP output sends credentials to WireMock. The authorization value can be verified with base64encode.org, but transmitting credentials without HTTPS exposes them in cleartext; use certificates when security matters. section 5.8
