salasanasuojaukset

Salasanasuojaukset refer to security measures taken to protect passwords and password-related data. The primary goal of these measures is to prevent unauthorized access to password-protected systems, accounts, and data. Salasanasuojaukset involve various techniques to handle passwords securely, from storage and transmission to verification and authentication.

Storage of passwords is typically done using secure password hashing algorithms. These algorithms transform the plaintext password into a fixed-length string of characters, known as a hash value, which cannot be reversed back into the original password. Popular password hashing algorithms include bcrypt, Argon2, and PBKDF2. The use of salts is also common, as they make it more difficult for attackers to use precomputed tables, known as rainbow tables, to guess passwords.

When passwords are transmitted, either during login or password reset, they are often encrypted to prevent eavesdropping and interception. SSL/TLS (Secure Sockets Layer/Transport Layer Security) is a widely used encryption protocol that provides a secure channel for password transmission.

In addition to password storage and transmission, salasanasuojaukset also involve secure password verification and authentication protocols. Many systems use the concept of one-way authentication, where the server stores only the hash value of the password and verifies the input password by hashing it and comparing it to the stored hash value. Salasanasuojaukset are essential in preventing password-related attacks, such as brute-force attacks, dictionary attacks, and phishing attacks. By implementing robust salasanasuojaukset, organisations can protect sensitive user data and prevent potential security breaches.
