Creating a Secure TextboxCreating a Secure Textbox
The SecureString class holds confidential information in an encrypted format, reducing the risk that the information could be obtained by reading a computer's memory directly. However, there is no easy way to obtain the secure information from a user.
Generating Random Pronounceable PasswordsGenerating Random Pronounceable Passwords
The use of passwords as a security measure is increasingly common for technical and non-technical users alike. Generating passwords that are both strong and memorable can be difficult. This article describes one method to alleviate this problem.
Checking Password StrengthChecking Password Strength
Many computer systems require that a password is provided before permitting access to sensitive data. As some passwords are easy to crack using brute force techniques, it is common to give the user feedback to show the strength of their selected password.
Salted Password HashingSalted Password Hashing
There are many ways in which passwords can be stored, with varying levels of security. Salted password hashing uses a non-reversible hashing algorithm with the inclusion of a randomised element to make it more difficult to obtain user passwords.

Highly confidential information, such as passwords or banking details, should be encrypted in memory during use to reduce the risk that it may be revealed to malware or forensic examination. The SecureString class provides this encryption automatically.

User Account Control (UAC) protects Vista by preventing malware from executing various tasks that modify the operating system, its files or configuration. If you develop software that requires this access, you must elevate your program's privileges.

Modern secure software requires either a login name and password, or detects the current user and automatically assigns the correct permissions. In order to create a security system that requires no password, the current user must be identified.
