What output does PEM Blocks give me?
One block type per line, in order. The base64 body is not printed. If no block is found, the tool returns an error.
Is PEM Blocks free, and is my input private?
Yes — Your input is processed in memory for this request only. It is not saved to disk or the database, and it is cleared after the tool finishes.
Does this validate the key or the certificate?
No. It only reads the PEM armor labels. An expired certificate and a mismatched key still list their block types.
