read moreCryptography is the practice and study of techniques for securing information and communication.
Cryptography is used to protect data from unauthorized access.
It involves techniques such as encryption and decryption.
Common encryption algorithms include DES, 3DES, AES, and RC4.
Asymmetric encryption uses different keys for encryption and decryption, while symmetric encryption uses the same key.
Cryptography is essential for ensuring data confidentiality and integrity.

Q. Give a practical example of Broken Authentication & authorisation? How u will exploit that?
Broken authentication & authorization is when an attacker gains access to a user's account or system without proper credentials.
An attacker can exploit this by guessing or stealing a user's login credentials.
They can also use brute force attacks to crack weak passwords.
Another way is to exploit vulnerabilities in the authentication process, such as session hijacking or cookie theft.
Once the attacker gains access, they can steal sensitive data, modify or delete data, or perfor...read more
