Passwortübertragung

Passwortübertragung refers to the process of sending a user's password from a client to a server, typically for authentication purposes. This process is a critical aspect of online security. Historically, passwords were sometimes transmitted in plain text, meaning the password was sent exactly as the user typed it, without any encryption. This is highly insecure because any eavesdropper on the network could intercept and read the password.

Modern and secure systems employ various methods to protect password transmission. The most common and recommended method is using HTTPS (Hypertext Transfer Protocol Secure). HTTPS encrypts the entire communication channel between the client and the server using TLS/SSL protocols. This ensures that even if the data is intercepted, it appears as unintelligible gibberish to an unauthorized party.

Another important consideration is how the password is handled after transmission. While secure transmission prevents interception during transit, storing passwords insecurely on the server can still lead to breaches. Therefore, best practices involve hashing passwords on the server-side, rather than storing them in plain text. Hashing is a one-way process that converts the password into a unique string, making it computationally difficult to reverse and recover the original password. In summary, secure Passwortübertragung is fundamental to protecting user accounts and sensitive data.
