Situated in the southeast of Europe, Romanian Countries had an intense diplomatic activity, even if this was not recorded accordingly in documents of the day. This activity, as well as others made use of cryptography and cryptographic systems. Considering the scarcity of books devoted to this topic, the present paper is a survey regarding some of the encryption systems used in the Romanian Countries in the 15th -19th centuries, and will include a comparative approach between these and other encryption systems used in Europe at the same time.
