There are several effective cryptography techniques to secure your data. According to recent studies, global cybercrime is up nearly 500% due to COVID-19. Indeed, malware infections and email phishing schemes have increased significantly as businesses have shifted to remote work environments.

Therefore, cryptography is vital to mitigate cyber crime. As an enterprise development manager, you need to know the strongest cryptography techniques and leverage the most secure devops tools to protect your data from unwanted third parties. This way, you can ensure secure electronic transmission and prevent costly data breaches. Read on to discover the most effective cryptography techniques for secure data communication.

Symmetric Encryption

First, symmetric encryption is one of the most effective cryptography techniques for secure data transmission. By using symmetric encryption algorithms, you can convert your data into a form that is only comprehensible to those with the secret key. Once your intended recipient has the message, the algorithm reverses. This way, the message is returned in its original and understandable form. Typically, both the sender and the recipient possess the same secret key. Notably, they should be the only ones who know it, and it should be difficult to guess. Usually, it is a specific password or randomly generated string of letters and numbers for a stronger defense against third party data breaches. Since only the sender and recipient know the key, symmetric encryption is an effective technique for secure data communication.

Asymmetric Encryption

Next, asymmetric encryption is another powerful cryptography method to protect your data. With this method, each person has a private and public key. To send a message, you can look up your recipient’s public key. Typically, these are stored in an accessible repository. Once obtained, you use this key to encode your message. Then, your recipient can use their private key to decipher the message. Since asymmetric encryption is a more complicated cryptography method, it is often used to encrypt a symmetric key. Importantly, this adds another layer of protection to ensure confidentiality. Definitely, asymmetric encryption is a strong cryptography technique to protect your information online.

SSL & TLS Web Security Protocols

In addition, secure sockets layer (SSL) and transport layer security (TLS) web security protocols are another way to protect your data communications. Once a connection is made between a client and the server, the client typically requests a secure connection. It also requests information about what types of cryptographic security the client supports. Next, the server chooses the most secure option and sends a certificate signed with the server’s public key. Once verified, the client and server use the secret key to generate a pair of symmetric keys to communicate securely. To implement SSL and TSL protocols, you can use an openssl c++ library. This cryptography library provides a robust toolkit for smooth, secure protocol implementation. Certainly, SSL and TLS web security protocols are powerful cryptography techniques for secure data exchange.

Hash Functions

Moreover, hash functions are another way to amplify your data protection. Cryptographic hash functions are mathematical functions that transform or map a specific set of data. Typically, they organize the information into a fixed size bit string. Commonly, this is referred to as the hash value. Notably, a hash value with a fixed length is calculated according to plain text. This makes it nearly impossible for the contents of the plain text to be recovered. In addition, cryptographic hash functions can check message integrity and authenticate various information. Many operating systems use hash functions to encrypt passwords as well. Absolutely, hash functions are an effective online data security tip to safeguard your network communications.

Block Ciphers

Furthermore, block ciphers are another effective technique to secure your data communications. Notably, these ciphers encrypt data in blocks of bytes, instead of a single bit at a time. For example, the triple data encryption standard is a common clock cipher that uses 56-bit keys. Importantly, this method encrypts the data a full three times. Basically, this turns your 56-bit key into a 168-bit key. Since the data is encrypted three times, it is more secure for storage and transmission. However, it may not be as efficient as other cryptography techniques. Therefore, this particular block cipher may be best used for data that requires the highest level of protection, such as financial information. Undoubtedly, block ciphers are an effective cryptography method to secure data transmission.

There are several effective cryptography techniques to secure your data. First, symmetric encryption involves a single security key for the sender and recipient to protect the data. Next, asymmetric encryption utilizes a private and public key to add another layer of protection. In addition, SSL and TLS web security protocols are essential procedures to block hackers on your network. Moreover, you can also use hash functions to protect your data. Furthermore, consider block ciphers to secure your sensitive information. Implement these cryptography techniques to secure your data.
