It is a method of converting data to a smaller fixed value known as the key, which is then used to represent the original data. |
It's the technique of securely encoding data such that only the authorized user with the key or password can get the original data; for everyone else, it seems to be rubbish. |
By whatever method, the hash code or key cannot be reverted to the original information. It can only be mapped, and the hash code is compared; if the hash code is the same, the information is identical; otherwise, it is not. It is not possible to get the original data. |
If we know the encryption key and technique used for encryption, we can easily extract the original data. |
In comparison to encryption, it is more secure. |
In comparison to hashing, it is less secure. |
The goal of hashing is to index and retrieve data from a database. The procedure is really quick. |
Encryption transforms data in order to keep it hidden from others. |
The hashed data is usually short and constant in length. It does not increase in size as the length of information increases. |
The length of the encrypted data is not defined. It expands as the amount of data grows longer. |
