The Integrity of Distributive Data
In our last article, we discussed how Blockchain drives Distributive Data by recording and encrypting data using Public Key Cryptography across a vast network of computers. Now, let’s take a deep dive into the technology that binds the chain by creating digital fingerprints to index and verify the data – the Secure Hash Algorithm.
The Secure Hash Algorithm is the other major technology underlying Blockchain. One of the most popular forms of this technology is the 256-bit Secure Hash Algorithm (SHA-256). Although not technically encryption, the Secure Hash Algorithm is a one-way mathematical operation that takes data of any length and converts it into a 64-character code called a hash.
Hashing is a very useful tool when you want to verify that you possess a piece of information without showing or storing the information in its raw format. This is actually how most websites store your password— they don’t. Rather, they store the 64-character hash of your password matched to your username from when you signed up. When you log-in, whatever you type in the password field is hashed and checked against that record. Hashing is much more secure since raw password data isn’t stored, just 64 characters of mush.
What is the Secure Hash Algorithm
Since even the slightest change in the input will lead to a totally different hash, these algorithms are used as a means to create digital fingerprints in order to verify authenticity, ensure data haven’t been corrupted, and as a means to index and address.
Blockchain Technology Summary
Public-key cryptography converts data along with an attached public key into random looking numbers that can only be decrypted with the paired private key.
Hashing algorithms convert any amount of data into a unique 64-character mush pile and is used for creating digital fingerprints for verifying and addressing.
