Hashing is required when we have to compare a huge amount of data. We can create different hash values for different data, and we can compare hashes too.

Following is a list of some most important usage of Hashing:

• Hashing facilitates us to keep and find records of hashed data.
• Hashing can be used in cryptographic applications such as a digital signature.
• With the use of hashing, we can create random strings to avoid data duplication.
• Geometric hashing is a type of hashing used in computer graphics to help find proximity issues in planes.
