Koodivahetus

Koodivahetus is an Estonian term that literally means “code exchange.” It is not a single standardized concept, but rather a phrase used in several contexts to describe the process of exchanging coded information, identifiers, or source code between parties.

In security and cryptography contexts, koodivahetus often refers to key exchange—the sharing of cryptographic keys or secrets between communicating parties to establish an encrypted channel. This can occur through public-key infrastructures, pre-shared keys, or key agreement protocols, and is essential for ensuring confidentiality and authentication.

In software development and IT collaboration, the term may describe exchanging source code, configuration scripts, or code snippets. This includes practices such as code reviews, pull requests, and sharing repositories to enable collaboration, reuse, and improvement of software.

In marketing or consumer services, koodivahetus can describe the distribution and redemption of promo codes or discount codes, where customers exchange codes for offers or access to products and services.

Because of its broad usage, interpretation of koodivahetus depends on the context, and native Estonian speakers may specify the domain (security, software development, marketing) to avoid ambiguity.
