Salausmenettelyllä

Salausmenettelyllä is a Finnish term that translates to "by means of encryption" or "using encryption". It refers to the process of encoding information in such a way that only authorized parties can understand it. This is achieved through the use of cryptographic algorithms and keys.

The purpose of employing encryption is to ensure confidentiality, integrity, and authentication of data. Confidentiality means that sensitive information is protected from unauthorized access. Integrity ensures that the data has not been altered or tampered with during transmission or storage. Authentication verifies the identity of the sender or the source of the data.

Salausmenettelyllä is a fundamental concept in cybersecurity and is used across a wide range of applications. This includes securing online communications like email and web browsing (e.g., HTTPS), protecting stored data on computers and mobile devices, and enabling secure transactions in financial systems. Various encryption methods exist, broadly categorized as symmetric encryption, where the same key is used for encryption and decryption, and asymmetric encryption, which uses a pair of keys: one for encryption and another for decryption. The specific method employed depends on the security requirements and the context of its use.
