Base64 Decode

Decoding turns a Base64 string back into its raw byte sequence. That is useful when you inspect a configuration value, unpack a payload from an older integration, or reverse a data URL for local analysis.

Whitespace and newlines are common in PEM-style blocks; tolerant decoders strip them, but you should still validate the output type before writing files to disk.

Decoded content might be executable, archived, or otherwise unsafe if written blindly to disk. Treat unknown output like any download from the internet.

Never decode secrets into a shared screen recording without redaction, because decoded material can appear in editor history or clipboards unexpectedly.

If decoding fails, check for URL-safe alphabet variants, missing padding characters, or accidental truncation when copying from chat apps that wrap long lines.

Compare the decoded length with what your producer claims; mismatches often point to double-encoding or incorrect transport framing.
