Secret correspondence

Secret correspondence refers to private communication between parties that is kept hidden from others, often using encryption or confidential channels to protect the content. It ensures that messages cannot be accessed or understood by unintended recipients, maintaining privacy and security. This practice is common in diplomatic, legal, and technological contexts, where sensitive information must be safeguarded from interception, tampering, or unauthorized disclosure. Ultimately, secret correspondence balances the need for confidentiality with the importance of authentic, secure communication.
