Salauskaavoja

Salauskaavoja, also known as encryption algorithms, are mathematical procedures used to transform readable data, known as plaintext, into an unreadable format, known as ciphertext. This process is called encryption. The primary purpose of encryption is to ensure data confidentiality and integrity, protecting sensitive information from unauthorized access or tampering. Encryption algorithms use keys, which are strings of characters, to perform the encryption and decryption processes. There are two main types of encryption algorithms: symmetric and asymmetric.

Symmetric encryption algorithms use the same key for both encryption and decryption. Examples include the Advanced Encryption Standard (AES) and Data Encryption Standard (DES). These algorithms are generally faster and more efficient for encrypting large amounts of data. However, they require secure key distribution and management.

Asymmetric encryption algorithms, also known as public-key cryptography, use a pair of keys: a public key for encryption and a private key for decryption. Examples include the Rivest-Shamir-Adleman (RSA) algorithm and Elliptic Curve Cryptography (ECC). These algorithms provide a higher level of security as they do not require secure key distribution. However, they are generally slower and more computationally intensive than symmetric algorithms.

Encryption algorithms are widely used in various applications, including secure communication, data storage, and digital signatures. They play a crucial role in ensuring the privacy and security of digital information in today's interconnected world.
