FAQs on Introduction: Hashing Video Lecture - Algorithms - Computer Science Engineering (CSE)

1. What is hashing?

Ans. Hashing is the process of converting input data into a fixed-size string of bytes using a mathematical algorithm. This output, known as a hash value, is unique to the input data and is commonly used in data security and encryption.

2. How does hashing help in data security?

Ans. Hashing helps in data security by creating a unique hash value for input data. This hash value can be used to verify the integrity of the data, detect unauthorized changes, and securely store passwords without storing the actual password in plaintext.

3. What are some common hashing algorithms used in computer science?

Ans. Some common hashing algorithms used in computer science include MD5 (Message Digest Algorithm 5), SHA-1 (Secure Hash Algorithm 1), and SHA-256 (Secure Hash Algorithm 256). These algorithms are used for various security and data integrity purposes.

4. How is hashing different from encryption?

Ans. Hashing is a one-way function that converts input data into a fixed-size hash value, while encryption is a two-way function that converts data into a ciphertext that can be decrypted back into the original data. Hashing is primarily used for data verification and integrity checks, while encryption is used for securing data during transmission.

5. Can hash values be reversed to obtain the original input data?

Ans. Hash functions are designed to be one-way functions, meaning that it is computationally infeasible to reverse a hash value to obtain the original input data. However, with the use of rainbow tables and advanced computing resources, it is possible to attempt to reverse engineer a hash value to obtain the original input data.
