A - The act of enclosing one or more elements inside of a physical or logical container is known as encapsulation. B - Encapsulation limits access to implementation information in object-oriented programming.
a method for merging many data members and the member functions that are used on those data members into a single entity. Explanation: Encapsulation is an OOPS mechanism that implements the member functions on multiple data members into a single unit by combining the members of those data members. Although encapsulation and information hiding are similar concepts, the phrase is frequently used to refer to information hiding's practical application, particularly in object-oriented programming.

The method to extend a 64-bit key into a 1024-bit string is to use a key-derivation function (KDF).
What is key-derivation function?A key-derivation function (KDF) is a cryptographic algorithm used to derive a cryptographic key from a set of inputs such as a password, a random number or some other form of input. KDFs are used to transform user-chosen passwords into cryptographic keys that can be used to encrypt and protect data.
A KDF is a cryptographic algorithm that takes an input (in this case a 64-bit key) and produces an output with a longer length (in this case 1024 bits). The KDF will take the 64-bit key and generate a 1024-bit string by stretching it out with random numbers, algorithms, and/or calculations.
The resulting cipher may not be as secure as a one-time pad, as it is not truly random. Depending on the KDF used, it is possible for an attacker to figure out the KDF used and then reverse the process to determine the key.
It is not possible for any such cipher to be as secure as a one-time pad, as one-time pad encryption relies on a truly random key (which is impossible to reverse engineer).
