S/MIME is used most often in corporate settings. In these cases, administrators supply certificates that they have purchased from a certificate authority. In some cases, an organization can act as its own certificate authority, with or without a guarantee from a dedicated authority such as VeriSign* or Thawte*. In either case, the system administrator provides you with a certificate file.

Nolanahi ere, sistema-administratzaileak ziurtagiri-fitxategi bat ematen dizu.
