Encryption, Hashing, Encoding Explained

Table of Contents

You may have heard of several types of cryptography before: encryption, hashing, and encoding. It can be unclear to know the difference between them, so in this blog post, we’ll explain each and help you understand when each should be used. Let’s get started.

Encryption explained

Encryption is such a way to make your information unreadable by strangers. It’s like transforming it so that only those who should have access can understand what you’re saying or writing.

And actually, encryption ipensn’t just about making things difficult for eavesdroppers. It also serves another important function: keeping hackers out so successfully they can’t get through even when there are no barriers. However, the result will be plenty enough without help from mathematics.

These days most people think nothing more than twice about the safety of their email. But for those handling truly sensitive information, encryption is a must. It’s not just top-secret government files that must be kept out of prying eyes.

If you’re dealing with personal medical records, financial data, or anything else, you wouldn’t want them falling into the wrong hands; encryption is the best way to protect your information.

Symmetric key encryption

The best mechanisms to protect your binary data are based on mathematical encryption algorithms that can only be solved by possessing a private key or through advanced computational power.

Two families exist symmetric-key encryption methods, which use one selfsame set (or “same key”) both for enciphering messages as well as deciphering them; and asymmetric encryption schemes like those created buried(RSA), where each party has its very own unique digitized signature, no matter how many people there may else have access.

When it comes to encryption, the most important thing is to know what you’re trying to protect and then find the right tool for the job.

A few options are available if you’re looking to encrypt your email communications. PGP (Pretty Good Privacy) is one of the most popular methods, and it uses a public key system to encrypt and decrypt messages.

However, it should be noted that PGP has been known to be cracked in the past, so it’s not necessarily the most secure option out there.

Examples of Encrypted data

The purpose of encryption is to make data unreadable and challenging for others who do not have authorized access. It does this by transforming it from one representation into another so that people may misunderstand what they see or hear and lose any personal information attached to the original input.

A lot has been written about whether we can call Encoding a form OF encoding, but there’s no mistaking why developers all over seem obsessed with efficiency; it’s the key to how we make our code go further & do more with less.

Hashing explained

What is a hash algorithm? Well, it’s a technique to generate unique fixed-length strings (hashes) strictly depending on input data. Since these generated Codes depend upon specific IDs, any slight change in your precious words will lead you towards another entirely different Hash, thus ensuring their integrity when stored digitally or otherwise.

Hashing algorithms are a great way to ensure data confidentiality and integrity because they provide that you can know about something that changes.

Technically speaking, hashes take any input and produce fixed-length strings with the following attributes:

The same information always produces the same output; disparate inputs do not result in similar outcomes even after modifications have been applied; there will also be drastic differences between them since shifts only change certain parts while leaving others intact (such as in the case of a collision).

It is computationally infeasible to produce an input that results in a given same hash value output. You can think of hashes like digital fingerprints for data.

The most common hashing algorithm used today is SHA-256, developed by the US National Security Agency (NSA). It is part of the SHA-2 family of such algorithms, including SHA-224, SHA-512/224, and SHA-512/256.

While SHA-256 is the most widely used hashing algorithm, it is not without its flaws. There have been several successful attacks against it in recent years.

Hash function

The two sentences have different words, capital letters, and lowercase characters. There is a big difference in these aspects, which tells us they were not written by the same person/users since we would expect them to use similar styles if both pieces of content were created at once instead just one or none whatsoever.

Good point, so let me explain how this works. The second version’s hash has a k replaced with a smaller letter, ‘K.’ Why do I care about comparing those strings when I could reach my entire media file?

Encoding explained

Encoding is a technique used to transform data from one format into another so that it can be understood and consumed by different systems. As the name suggests, what usually happens, in this case, are transformations of characters’ strings into bits, or “digital code.”

Examples of Encoding

There are two different ways to represent information. One is through letters and the other as bits, which computers can more easily process than human systems.

Encoding usually involves converting one form of data into another with an alpha-numerical code table (such as ASCII) that maps each letter or symbol in your original document onto its corresponding location within this new bit-string version, just like turning words into numbers.

The internet is a vast, ever-changing place. It’s evolving and diversifying with new technologies that were never imaginable when HTML first took off in 1996. For example, character encoding.

There are many ways to represent text without using letters alone; emojis & other symbols can be stored compactly by Base64 encoding, while images get their particular URL encoding structure just for them.

Encryption hashing encoding key difference?

Encryption transforms readable data into an unreadable format, then back to its original form using technology to encrypt data and decrypt data. Encoding transforms data, takes readable data, and turns it into an unreadable format without changing the information itself. Hashing is taking a string of text and turning it into a unique identifier.

Encryption is used when you want to keep the information confidential. For example, if you send someone a message that only they can read, you would encrypt it before sending it to them. The recipient would then need to decrypt the data to read it.

Hashing is used primarily for security purposes. When you hash data, you create a unique identifier for that data that cannot be reversed. This can be used to verify that data has not been tampered with, as any changes to the data will result in a different hash.

Encoding is often used to store or send data over a network efficiently. For example, when you encode data as JSON, it takes up less space than if stored as XML. When you send data over a network, it must be encoded and transmitted correctly.

The Right Tool to transform data

It may seem like there are many options for encryption, but they all have specific purposes and features. Confusion about these capabilities can lead you down an insecure path where your systems’ security could be compromised by a hacker who has access to the information needed for cracking codes, even if he doesn’t know how to do so.

For this reason alone, we recommend taking precautions such as changing passwords on EVERY service/website combination and keeping an up-to-date backup of your essential files in case you are hit with ransomware or another type of malware that could potentially lead to a loss of access.


So, what is the difference between encryption, hashing, and encoding? Encryption turns data into an unreadable format, so authorized users can only access it.

Hashing takes input data and creates a fixed-length output string called a hash value or message digest. This output is generally shorter than the original, making it more secure.

Encoding takes the user-friendly text and converts it into a format that machines can read. By understanding the differences between these three processes, you can choose the right one for your needs.
