Is Podepisovací komponenta Signer safe?

Clean risk

Podepisovaci komponenta Signer forwards selected site messages to the local ace.nmsigner native host.

On matching intranet, Asseco, and Czech or Slovak healthcare portal domains, the content script accepts same-window FROM_ACE_SIGNER messages and sends their method and parameter fields to the extension background script. The background script connects to the local ace.nmsigner native messaging host, forwards those values, and posts the host's response back to the page; the code does not show a remote network endpoint.
