Everything is being digitalized as we move towards the generation. Innovation is at its highest peak, specifically in technology. Technology is everything in today’s world. For example, where the early generation was satisfied with the computer nowadays, even laptop sometimes does not satisfy the individual. Along with this, privacy and security have become an issue, such as security of data (information). Today we are going to discuss the types of data i.e. encrypted and unencrypted. It is not only important to understand this but to know its importance and consequences as well.
Encrypted vs Unencrypted
The main difference between encrypted and unencrypted is that encrypted is the data which is turned into ciphertext using an encryption algorithm and has access to the only authorized party. By doing this, the data is made more secure, whereas unencrypted is nothing but a plain and normal text which is not secure or encoded by any algorithm.
Encrypted is the type of secure data which is encoded. Only a key provided to an authorized party can help decode it. Otherwise, no one can understand what information that data has. It is a way of protecting crucial information/data from any frauds or mishappenings. This process is done by using various encryption tools.
Unencrypted is the opposite of encrypted i.e. any data which is not secure and is available t be understood without any decoding. This could be a document or e-mail. Most data that is not very crucial and can cause nor harm is left unencrypted or as plain.
Comparison Table Between Encrypted and Unencrypted
| Parameters of Comparison | Encrypted | Unencrypted |
| Definition | Encoded data | Normal data |
| Referred as | Cipher Text | Plain text |
| Security | It is more secure. | It is not secured at all. |
| Access to data | Only the authorized party can have access. | Anyone can have access. |
| Tools | There are several tools. | No tools are used as such. |
What is Encrypted?
The process of encoding a plain or normal text into ciphertext by using an encryption algorithm is known as Encryption. The reason for encrypting the data can be:
- Privacy: being more digitalized does not imply the breach of privacy and ensures this Encryption is done. Sometimes people want privacy in data that only chosen people can have access to it. Therefore data is being encrypted.
- Security: it is important to make sure data is secured from falling into the wrong hands. Cybercrime and fraud are prevented by doing so.
- Authentications: a key is provided to the owner and everyone who can have access to the data. Except for them, no one can understand the data.
- Regulations: many organizations have few rules to encrypt the data.
Types of techniques of Encryption are:
- Symmetric Encryption Method: it is also known as private-key cryptography or a secret key algorithm. Under this method, the sender and receiver must share the same key for access. This is considered best as no access to a third party is provided.
- Asymmetric Encryption Method: it is also known as public-key cryptography. In this technique, there are two mathematically connected keys which are called a private key and a public key.
- Hashing: under this technique, once data is encoded, it cannot be decoded. It creates a unique signature.
Different types of Algorithms used for Encryption are AES, Triple DES, RSA, Blowfish, Twofish, and Rivest-Shamir-Adleman (RSA).
What is Unencrypted?
Any data which is not encrypted (not encoded with an algorithm) is Unencrypted. It can be easily read and understood without and password or knowledge of Encryption.
An unencrypted that has the following limitations:
- Lack of Security: Well, obviously, if the data is not encoded and is plain text, there is no security to it. It can be understood even by the person who will misuse it for his benefit. Therefore the main and biggest disadvantage an unencrypted data has is that it is not secured at all. This has lead to an increase in cybercrime and frauds all over the world.
- Vulnerable: it vulnerable to crimes and misuse by any person. Data is being held in the wrong hands, and a price always has to be paid for this circumstance.
- Lack of privacy: there is no privacy with unencrypted data as everything is public. Therefore any private detail needs to be encrypted.
Advantages:
The only advantage it has is that no extra effort has to be made to read or understand the data. It is written in the raw form; therefore, no time has to be waste for getting the access or some key.
It is a decision that has to be made whether a data has crucial information that should be secured or not. Otherwise, data should remain unencrypted.
Main Differences Between Encrypted and Unencrypted
- Encrypted means any data which is protected by an encryption algorithm. Whereas unencrypted is the opposite of encrypted, which means anything which is not encrypted or protected.
- Encrypted is also known as the ciphertext, which cannot be understood easily, whereas unencrypted is also known as plain or normal text.
- Only the authorized party has access to the information encrypted; therefore, no other person can have access to it, whereas unencrypted being insecure can be accessed by anyone.
- To decode the encoded encrypt, a decryption key is required, but no such key is required in case of unencrypted.
- Encrypted is far more secure than unencrypted, which is not secured at all.
- There are various tools used for encryption methods, but no such tools are used for unencrypted.
- Encryption data cannot be understood until decoded, while there is no difficulty arises while understanding the unencrypted data.
Conclusion
It is very easy to differentiate between the both. Any person can do that. While most of the data is unencrypted but the crucial data that has some major information about something is then encoded by using some tools so that it cannot befall into wrong hands. Because as we know, technology is being developed everyday risk or cybercrimes, and hacking is also being increased with it.
People misuse information about anything for their motive, and to make sure this does not happen, data is encrypted. But still, there is data which do not require to be encrypted as it will not cause any harm to anyone. It could be anything from a message to a word document.
