Difference Between Hashing And Encoding. In this article, you will read about what is hashing, what is encoding, and what is the main difference between hashing and encoding. Both the terms are related to each other, but there is a difference between them. Let us differentiate between hashing and encoding.
What Is The Main Difference Between Hashing And Encoding?
The main difference between hashing and encoding is that the:
-Hashing is a process in which data is converted into a unique number that is generated from a string of text. It is a mathematical operation. The hashing output cannot be converted into its original form.
-Encoding is the process in which we put simple characters into a special format to make them used by other systems. It is a character by character substitution of characters.
What Is Hashing?
Hashing is a process in which data is converted into a unique number that is generated from a string of text. It is a mathematical operation. The hashing output cannot be converted into its original form. Hashing is used to verify the data.
The output in hashing is known as hash or message digest. The input in hashing has an arbitrary length, but the output is always fixed in it. In hashing, the hashing algorithm is used to convert the data. But the data cannot be converted back into its original form. A unique data will produce the same hash. The process of hashing is easy to perform, but very difficult to reverse. Some various hashing functions are MD5, SHA1, and SHA-256.
What Is Encoding?
The process in which simple characters are transformed into special and secured characters is known as ‘Encoding’. The computer used the process of encoding to make the data into another format. So that many other systems can use it. Encoding is not used for security purposes. The most common code or algorithm that is used by computers for text files is ‘ASCII’. It stands for American Standard Code For Information Interchange. This code is the combination of Upper and lower case alphabets, punctuation marks, numerals, and common symbols. Other various types used for encoding are Unicode, Uuencode, BinHex and MIME. The process of encoding also means analogue-to-digital.
