Encryption vs Hashing
Summary: Difference Between Encryption and Hashing is that Encryption is the process of converting readable data into unreadable characters to prevent unauthorized access. While the process of converting a string into a shorter-fixed length value or key that represents the original string is known as Hashing.
Encryption is the process of converting readable data into unreadable characters to prevent unauthorized access. You treat encrypted data just like any other data. That is, you can store it or send it in an e-mail message. To read the data, the recipient must decrypt, or decipher, it into a readable form.
In the encryption process, the unencrypted, readable data is called plaintext. The encrypted (scrambled) data is called ciphertext. An encryption algorithm is a set of steps that can convert readable plaintext into unreadable ciphertext. Encryption programs typically use more than one encryption algorithm, along with an encryption key. An encryption key is a programmed formula that the originator of the data uses to encrypt the plaintext and the recipient of the data uses to decrypt the ciphertext.
The process of converting a string into a shorter-fixed length value or key that represents the original string is known as Hashing. Hashing is used in database for indexing and retrieving items, because it is a fast way to find a text using shorter hashed Key. Instead finding it from the original string hashed key makes it easier. Lets take an easy example of hashing in a database, database of names will look like.
Each of these names would be the key in the database for that person’s data. When database start looking for some name, it will look in each character until it finds out the one its searching for. But if the names were hashed by using Hashing, it will be easy to look for specific name by giving that name a specific key.
