Cryptocurrency transactions are always known for their well-tight security and confidentiality features. These features are visible and maintained in their transaction processes. For this, it is important to know more about the encryption process.
Encryption is an important term in cryptocurrency transactions. It can be considered a form of secured data or information converted to a ciphertext. Ciphertext refers to the transformed plain text using a unique algorithm.
Someone can break the key and secure the information only if they have the code. Encryption provides the solution to transform important data and information that is unreadable to a third party.
This process ensures the security and confidentiality of the data being passed. Public and private keys are two methods of encryption. These two methods play a pivotal role in balancing security and integrity in cryptocurrency transactions.
The following sections of the article aim to provide a detailed analysis of private and public key encryption, its differences, and the various benefits and challenges they offer.
Understanding Public and Private keys in cryptography
In cryptography, a key can be considered a string of characters or bits that stores important information and data. This information is secured in the key and should not get leaked due to any circumstances. The keys are made using unique algorithms that make them differ from each other.
Usually increased and complex bits are used to make the keys to enhance the security of the information and data stored in the key. There are two types of keys namely public keys and private keys.
Both these keys have become a vital part of the field of cryptocurrency. Public and private keys have made the transaction process more convenient and safer. Using the keys, you can send the money from any location and it also does not require a third party for transaction processes.

Public keys
Public key encryption is used to receive transactions. It is only able to obtain the transactions when it is paired with a private key. A private key is needed to unlock the transaction done to the public key.
This is processed this way to confirm maximum security and to know if you are the owner of the cryptocurrency transaction.
Private keys
A private key is used for both encryption and decryption processes. The user and the sender can both use the private key thus it is also called “symmetric”. This type of key is used to prove the ownership of cryptocurrency transactions.
Differences between private and public keys
In this section let us look at a detailed comparison of public and private keys.
Public keys
- Public keys are used for encryption only.
- The key can be shared by anyone publicly.
- The mechanism process is much slower.
- It is used freely and publicly and not kept as a secret.
- It can be used for digital signatures.
Private keys
- Private keys are used for both encryption and decryption.
- The key can only be shared between the two parties.
- The mechanism process is faster.
- It is kept as a secret and not known to the public.
- It cannot be used for digital signatures.
Benefits and limitations offered by public keys
Benefits
Public key offers more secure communication even though it involves interruption from third parties. The secured data can only be decoded using a private key. Public key encryption also ensures the integrity of the transmitted data. The sensitive data cannot be altered or changed by a third party during the transmission process.
One of the best benefits is the adaptability or scalability of public keys to a larger number of people. This makes it ideal to be used in business surroundings and governmental agencies.
Limitations
Even though the public key is considered to be a powerful method of encryption, it also offers some challenges. A public key can be interrupted by a third party. So if a hacker from outside can decode the key, then all the information will be leaked.
Another limitation that the public key faces is when a third party tries to impersonate one of the parties involved in the transaction process. This way sensitive data and information can be leaked.
The mechanism or the working process of public key encryption is much slower compared to private key encryption and this can cause problems in the transactions.
Benefits and limitations offered by private keys
Benefits
One of the most efficient and beneficial factors of the private key is that it uses the same key for both encryption and decryption processes. For this only less effort and time are required.
There is no interruption of a third party making it well-secured to carry the sensitive data and information. The working process is faster and it can carry large volumes of data and information in real time.
Limitations
Even though Using the same private key for encryption and decryption offers benefits, it also paves a few challenges. It reduces the scalability as many private keys cannot be distributed among multiple people at the same time. It is also crucial to maintain the confidentiality of the key during the distribution process.

Conclusion
As a finalizing note, it can be concluded that public and private key encryption is an essential and fundamental part of cryptocurrencies. What makes them more important is the fact that they give a clear view of the cryptocurrency transaction process.
We can see the inner workings of such digital transactions thus providing transparency. The use of private and public key has come to use to improve security. Security has become one of the most concerning issues among many business and government sectors.
Since cryptocurrency transactions are built on high confidentiality and integrity, private and public encryptions are beneficial for secured transaction processes. Cryptocurrency ensures these factors through the encryption process.
The encryption makes it impossible for a third party to decode the key and retrieve the data and information. The public and private key collaborates to build a secure platform for cryptocurrency transactions.
