Hash algorithms are like magic formulas that turn any data into a short code, called a hash or a digest. They are good for checking things, not for hiding things. This means that you can use them to make sure that the data is not changed, fake, or stolen, but not to keep it secret.
One of the main characteristics of hash algorithms is that they are secure, meaning that they are non-reversible functions. This means that it is impossible or extremely difficult to find the original data from the hash, or to find another data that produces the same hash. This property makes hash algorithms useful for storing passwords, generating digital signatures, or detecting tampering.
Another characteristic of hash algorithms is that they produce fixed-size digests, regardless of the length or size of the input data. This means that a short text or a long file will have the same hash length. This property makes hash algorithms efficient and consistent for comparison purposes, as they reduce the amount of data to be processed and stored.
A third characteristic of hash algorithms is that they are unique, meaning that two different data sets cannot produce the same digest. Also known as collision resistance, this property ensures that each hash is a unique identifier for the data. This property makes hash algorithms reliable and accurate for comparison purposes, as they prevent false positives or duplicates.
Hash algorithms are used a lot in different areas and uses, such as secret codes, computer science, crime solving, and blockchain. Some examples of well-known hash algorithms are MD5, SHA-1, SHA-2, and SHA-3 .
What is Hash algorithms?
Hash algorithm is primarily used for comparison purpose, not for encryption
Many secure Hash Algorithms have three basic characteristics:
1. Secure - Non-reversible function
2. Fixed size - Short or long data will produce the fixed-size digest
3. Unique - Two different data sets cannot produce the same digest

Why hash algorithm is best?
Hash algorithms are like secret recipes that make short codes for any data, making it simple to see if anything is different.
⦁ You can often use them for keeping passwords, as keeping codes instead of normal passwords makes it harder for hackers to get them.
⦁ Moreover, hash algorithms help in making sure messages are real and not changed, by adding special codes or signatures to them.
⦁ Additionally, you can use them in finding and removing the same files quickly, by comparing their codes instead of the whole files.
⦁ Finally, hash algorithms make data easier to find and use, by using codes as keys to access them.
