โ‡๏ธ What is password salting ?

Password salting is a technique to protect passwords stored in databases by adding a string of 32 or more characters and then hashing them. Salting prevents hackers who breach an enterprise environment from reverse-engineering passwords and stealing them from the database.

Password salting increases password complexity, making them unique and secure without affecting user experience. It also helps prevent hash table attacks and slows down brute-force and dictionary attacks.

โ‡๏ธ Password hashing and why salting is required

Hashing prevents passwords from being exposed or stolen by threat actors, since they are not stored as plaintext. For example, when users create an account with a username and password on a website, their password is hashed and stored in an internal file system in an encrypted form.

When users log in, the password runs through a one-way hashing algorithm that converts the password into a different and unrecognizable string of characters. During login, this string is compared to the other hashes stored in the website's database. If the credentials match the stored hash, users can access the account. If it doesn't match, hash verification fails, and users are not able to log in.

5 SQL Queries Every Data Engineer Must Master (with Examples)

SQL has been the backbone of #DataEngineering for years. Whether youโ€™re building pipelines, optimizing databases, or troubleshooting, mastering these concepts is crucial:

๐Ÿ”น 1๏ธโƒฃ Aggregation and Grouping
Efficiently summarize and analyze data with key functions like SUM, COUNT, AVG, MIN, MAX, and GROUP BY.

๐Ÿ”น 2๏ธโƒฃ Window Functions
Perform advanced analytics like rankings, running totals, and comparisons while preserving row-level detail. Learn functions like ROW_NUMBER, RANK, NTILE, LAG, LEAD, and windowed SUM.

๐Ÿ”น 3๏ธโƒฃ Join Operations
Combine data from multiple tables using INNER JOIN, LEFT JOIN, RIGHT JOIN, FULL OUTER JOIN, and CROSS JOIN.

๐Ÿ”น 4๏ธโƒฃ Subqueries and CTEs
Simplify complex queries with WITH statements, or use subqueries in SELECT, FROM, and WHERE clauses to enhance readability and performance.

๐Ÿ”น 5๏ธโƒฃ Data Cleaning and Transformation
Prepare your data with functions like DISTINCT, LOWER, UPPER, TRIM, REGEXP_REPLACE, and COALESCE to ensure high-quality outputs.
