The Most Secured Types of Encryption

A secure encryption is very essential to protect online platforms. There are various kinds of encryption.

There are three fundamental encryption types with varying uses. Symmetric encryption allows for the protection of data at rest on a device or in the cloud. It is by far one of the simplest yet the strongest form of encryption which uses a symmetric key for data at rest in a computer or in the cloud. Its keys are generally 128 or 256 bits long. Symmetric encryption means that it uses the same key to encrypt the original text resulting to an unreadable cyphertext and decrypted original text.

Symmetrical encryption is limited in its use in a way that algorithms such as AES are unable to expertly share information across a network spanning various and multiple parties. During times when a big number of people need to access the same data, there has to be a way to distribute the keys without the danger or fear of it being intercepted.

Due to this limitation, there is a difficulty in using symmetric encryption when working across a big network since there is generally an absence of secure ways to transmit the key across the whole network without the presence of another layer of encryption. Furthermore, with symmetric encryption, only the user has access to the key and not the original creator of the device or the algorithm, thus when the password is accidentally forgotten, or the key is lost, then the encrypted data will most probably become undiscoverable.

Asymmetric encryption, on the other hand, protects data in motion during transmission, since symmetric encryption has limitations in sending data across the network, asymmetric data can protect data while it is in motion. It uses a pair of keys with a public key and a private key. Asymmetric encryption is used in a variety of ways, to establish a safe and secure connection along with encrypting emails.

BSA The Software explains that nonetheless, asymmetric encryption technologies also have its own limitation as it can become very vulnerable to “man-in-the-middle attacks” characterized by a bad actor giving the same public key to two recipients each thinking that the key is exclusively theirs. Thus, the bad actor has the ability to be in the middle of the conversation, effectively decrypting information from the middle before it is passed along.

These challenges can be overcome, and ways can be taken in order to ensure that the correct public key is being used and that the keys are distributed to verified and legitimate entities using a trusted software. Secure websites, for example, need to obtain a certificate from their own HTTPS server which in turn comes from a trusted certificate authority. Due to the permission is given by certificate authorities for browsers by signing keys, websites are then able to send public keys allowing the web browser to know that they can indeed trust the public key and thus effectively initiate a secure connection.

Authenticating a person, device or computer is the process of reassuring that the people on both ends of a process are legitimate. Hashing is one essential technology to protect passwords. It is a very common technique to protect passwords when a website is hacked and attacked by cybercriminals.

Specific examples of encryption include:


Triple DES is designed to replace the original Data Encryption Standard (DES) algorithm since hackers eventually learned to defeat the previous one with relative ease. Triple DES is the newly recommended standard and is considered the most widely used symmetric algorithm in the industry.


RSA is considered the standard for encrypting data on transit being sent and received over the internet. RSA is considered asymmetric since it employs a pair of keys. The resulting product of an RSA encryption is very difficult to understand and comprehend for attackers.


Twofish is the successor of the older Blowfish, it was considered by the US government in finding its cryptographic standard. It is a very flexible algorithm that works really well with smaller sized computers and it comes with free licensing and copyright for all users.


Advanced Encryption Standard (AES) is highly resilient against known attacks; it is used by the US government since its encryption is very useful for protecting classified information.

These kinds of encryption are indeed very important in protecting data privacy and consequently maintaining safety and security of a wide array of institutions and industries’ data, thus it will never hurt to research on these and employ the best program to enjoy all the perks and pleasures of encryption.
