Hashing and encryption are not new concepts. In fact, they are the most fundamental operation of computational systems. Working in a similar technique, both transform data into a different format. While hashing gives the original data a hash value, encryption changes it into ciphertext. Nevertheless, their conversion mechanism, as well as their use case can be quite different.
Here’s the difference - Hashing Vs Encryption
Encryption is the process of encoding data to protect it from unauthorized viewers. With this technique, you are transforming your data into a different and unreadable format. This information would not have any value unless you have the access key, which can decrypt the encrypted data back to its original form.Encryption brings about a lot of advantages as it can keep your data safe and more secure from others. The mechanism can also be implemented for a cheap price. With a protected layer for your data, you can easily share your file securely.However, the security vulnerability of encryption lays in its key. As encrypted data can be transferred, so does its key. Hence, to tamper with the original file, unauthorized viewers only need to focus on gaining that key. The most common type of attack for cryptography is to use brute force and try random keys until the right one is found. Additionally, if the data owner lost or forgets this key, he himself will not be able to access the data
On the other hand, hashing gives a unique hash value to the original data. Through this process, any size of data will be converted into a fixed value. This value is completely immutable, hence, impossible to hack through. If any user tampers the original data, its hash values will be altered completely. Therefore, one of the main applications of the cryptographic hash function is the verification of tamper-proof.
The main difference between Hashing and Encryption is that Hashing is indecipherable one-way encryption. While in the previous method, you can have access to decrypt the ciphertext with a key, hashing makes it impossible to see the original data. However, the hash value collates with the original value. Hence, hashing mechanisms are good at keeping track of the originality of the source.
To record data with high security and privacy, BLOOCK uses hashing mechanisms.Through our multilanguage SDKs, you can generate hashes for your data. This serves as the unique encrypted fingerprint of your original file. By doing so, you are using BLOOCK while keeping your data safely on your server. Once you have your hashes, no external agent will be able to decrypt your hash to retrieve the data it represents. By employing BLOOCK advanced algorithms, we accumulate all multiple hashes in a single block, which can hold up to 100 million hashes. You, or your customers, can verify at any time if the data has been tampered with by comparing it with the one stored in the Blockchain.The use of hash also helps BLOOCK to be compliant with GDPR/CCPA as well. Since BLOOCK helps your business upload hashes to Ethereum Mainnet, we fulfill the requirements of data confidentiality.
