What is the purpose of comparing the hashed password with the stored hash during authentication?
The purpose of comparing the hashed password with the stored hash during authentication is to verify the identity of a user attempting to access a system or application. This process is a fundamental component of authentication in web applications and plays a important role in ensuring the security and integrity of user accounts. When a
What is the purpose of using a slow cryptographic hash function for password hashing?
A slow cryptographic hash function is commonly used for password hashing in web applications security for several reasons. The purpose of using a slow cryptographic hash function is to enhance the security of password storage and protect user credentials from unauthorized access. This approach is an essential aspect of authentication systems in web applications, as
How is a MAC computed using a secret key and the message itself?
A Message Authentication Code (MAC) is a cryptographic technique used to ensure the integrity and authenticity of a message. It is computed using a secret key and the message itself, providing a means to verify that the message has not been tampered with during transmission. The process of computing a MAC involves several steps. First,

How does a MAC ensure the integrity and authenticity of a message?
A Message Authentication Code (MAC) is a cryptographic technique used to ensure the integrity and authenticity of a message. It provides a way to verify that a message has not been tampered with and that it originates from a trusted source. In this explanation, we will consider the inner workings of MACs and how they
How does AES ensure confidentiality and integrity of sensitive information during data transmission and storage?
The Advanced Encryption Standard (AES) is a widely used block cipher cryptosystem that ensures the confidentiality and integrity of sensitive information during data transmission and storage. AES achieves these goals through its secure design and implementation, which incorporates several key features and techniques. Confidentiality is achieved through AES's use of symmetric encryption, where the same
