HackerRank's programming challenges can be solved in a variety of programming languages (including Java, C++, PHP, Python, SQL, and JavaScript) and span multiple computer science domains. [ 2 ] HackerRank categorizes most of their programming challenges into a number of core computer science domains, [ 3 ] including database management ...
Alice wants to log into Bob's server. She needs to prove she is who she claims to be. For solving this authentication problem, Alice and Bob have agreed upon a password, which Alice knows, and which Bob knows how to verify. Now Alice could send her password over an unencrypted connection to Bob in a clear text form, for him to verify.
Some systems attempt to derive a cryptographic key directly from a password. However, such practice is generally ill-advised when there is a threat of brute-force attack. Techniques to mitigate such attack include passphrases and iterated (deliberately slow) password-based key derivation functions such as PBKDF2 (RFC 2898).
The salt and hash are then stored in the database. To later test if a password a user enters is correct, the same process can be performed on it (appending that user's salt to the password and calculating the resultant hash): if the result does not match the stored hash, it could not have been the correct password that was entered.

First, it means searching for class and function declarations, usages, variable and field read/write, etc. IDEs can use different kinds of user interface for code search, for example form-based widgets [10] and natural-language based interfaces. Second, it means searching for a concrete implementation of some specified functionality.
Password-authenticated key exchange (PAKE) is a method in which two or more parties, based only on their knowledge of a shared password, [1] establish a cryptographic key using an exchange of messages, such that an unauthorized party (one who controls the communication channel but does not possess the password) cannot participate in the method ...
The purpose of password cracking might be to help a user recover a forgotten password (due to the fact that installing an entirely new password would involve System Administration privileges), to gain unauthorized access to a system, or to act as a preventive measure whereby system administrators check for easily crackable passwords.
