About Code Secret Scanner

Use Code Secret Scanner when you need a focused result without installing a separate desktop application. Scan pasted code for patterns resembling exposed API keys, tokens, private keys and credentials. The result changes when the source data or selected options change, so it is easy to run a second comparison.
