cryptography is a cornerstone of the modern security technologies used to protect information and resources on both open and closed networks. Cryptography is the science of providing security for information. It has been used historically as a means of providing secure communication between individuals, government agencies, and military forces

Login security in crytography?
Login security in cryptography involves techniques that protect user credentials during authentication processes. This includes the use of hashing algorithms to securely store passwords, ensuring that they are not easily retrievable even if a database is compromised. Additionally, implementing multi-factor authentication (MFA) adds an extra layer of security by requiring users to verify their identity through multiple methods. Overall, these cryptographic practices help mitigate the risk of unauthorized access and enhance the overall security of user accounts.
