Encryption category types will explain the overarching and basic categories of classification for encryption, including the two most important: symmetric and asymmetric encryption.
Encryption tool types will discuss the major classifications of encryption tools available for use by an organization.
We provide the additional distinctions to help better explain how encryption works and to better illustrate the tool to use for specific use cases.
An encryption category type provides an overarching classification that encompasses multiple encryption algorithms or tool types.
The two most important encryption categories are symmetric and asymmetric encryption.
These critical encryption concepts encompass the vast majority of encryption algorithms and tools currently in wide use and can be used in combination for secure communication.
Symmetric encryption is often used for drive encryption, WiFi encryption, and other use cases where speed performance is paramount and a password can be safely shared.
Although more complicated and expensive to implement, asymmetric encryption ensures secure communications over distributed networks without exposing the encryption keys to theft.
Asymmetric encryption does not use multiple rounds for encryption but instead uses variable-length, large sized prime numbers.
Symmetric Asymmetric Keys 1 - Private 2 - Public and Private Bits 128 - 192 - 256 2,048 - 4,096 Speed Faster Slower Overhead Less complex and expensive and use less memory and processing power More complex and expensive and use more memory and processing power Security Risk Vulnerable to key theft, should not be used for sharing encrypted data,quantum computers can guess keys Quantum computers can guess keys Examples AES, Blowfish, 3DES DHM, RSA, ECC Use Cases Full drive encryption, WiFi data encryption Website communication, proving identity Symmetric + Asymmetric Encryption.
These databases cannot tolerate variances caused by many encryption algorithms that intentionally add padding to short encryption to obscure the length of the original data or convert both letters and numbers into hexadecimal code.
Format-preserving encryption can use existing encryption algorithms, such as AES. However, programmers typically incorporate specially designed algorithms so specialized that we will not cover them in more detail in this article, such as the Thorp Shuffle, Variable Input Length Ciphers, and the Hasty Pudding Cipher.
Encryption algorithms are defined by the specific math formulas and the process required to perform an encryption transformation.
The Blowfish encryption algorithm was released to the public without a required license and is known for its flexibility, speed, and resilience compared to other older encryption standards.
Significance: Popular asymmetric encryption alternative to RSA. Pros: Faster than RSA and uses smaller key sizes, more secure for sharing than symmetric encryption algorithms.
File encryption tends to require more user interaction and is more difficult to apply on a universal basis than full disk encryption.
File encryption can add strong security, but it remains vulnerable to stolen passwords and can be more vulnerable to lost passwords than full disk encryption, which may have an admin password established by IT. Email Encryption.
Email encryption options exist within major email tools, but many organizations choose to deploy additional tools with more robust options for deployment or encryption.
Add-on encryption is often a service provided by specific vendors for specific use cases, such as a cloud provider's cloud storage encryption added to protect cloud resources.
Encryption as a service offers a broad range of encryption options, will be continuously updated, and requires the least effort to manage; however, this option involves giving up control of company secrets to an outside party.
