titkosítással

Titkosítás is the Hungarian word for encryption. It refers to the process of encoding information so that only authorized parties can understand it. This is achieved by using an algorithm, known as a cipher, and a key. The original message is called plaintext, and the encoded message is called ciphertext.

There are two main types of encryption: symmetric and asymmetric. Symmetric encryption uses the same key for both encrypting and decrypting data. This method is fast and efficient but requires a secure way to exchange the key between the sender and receiver. Asymmetric encryption, also known as public-key cryptography, uses a pair of keys: a public key for encryption and a private key for decryption. This allows for secure communication without the need for prior key exchange, as the public key can be shared freely.

Encryption is fundamental to modern digital security. It is used to protect sensitive information such as financial transactions, personal communications, and confidential data stored on computers and servers. Common applications include secure websites (HTTPS), virtual private networks (VPNs), and encrypted messaging apps. The strength of encryption relies on the complexity of the algorithm and the secrecy of the key. Advances in computing power and cryptography are constantly evolving, leading to the development of more robust encryption methods.
