Cryptography Techniques

Cryptography Techniques: The Network Security Projects are the most vital thing that is useful for the security purpose. For the security purpose, here the encryption and decryption techniques are the essential processes. To mention that, the most crucial thing to perform encryption and decryption is the secret key. Hence the process with the secret key is the secret of cryptography and networking projects technology.

The Encryption Technique

In Cryptography Techniques, usually, the encryption is possible with the input of plain text and the secret key. The input is processed with the given secret key, and the receiving output is of cipher text. Typically, this is helpful to transfer a secure message. Hence, with this technique, the secure message is transfer to the receiver from the sender without any unethical hacking of the hackers.

The Decryption Technique

Likewise, the encryption process, the decryption technique is also possible with the secret key. The encrypted cipher text that is the output of the encryption process consider as the input for the decryption. The encrypted cipher text process with the similar given secret key and delivers the original plain text. To point out, this plain text is the given input key for the encryption.

Categories of Cryptography Techniques

The cryptography techniques are of two types such as substitution cipher and transposition cipher. Also, both these ciphers uniquely have its subseries and specific processes. Here are some famous cipher techniques.

1. Caesar Cipher

Usually, this cipher comes under substitution technique because it habits substitution to yield the output that is ciphertext. Sum the given input with the given secret key for the encryption process. Similarly, subtract the receiving output with the given key for the decryption process. This is the progress of the Caesar cipher technique to transfer the messages securely.

2. Play fair Cipher

This is also a substitution cipher that uses a keyword to split the given input text and process the encryption and decryption operations. To mention that, both the encryption and decryption use the keyword for the specific output.

3. Hill Cipher

Specifically, the hill cipher consists of matrix form that is to encrypt and decrypt the give inputs to yield a particular output. If you want to send a message to the receiver more securely, preferring this technique is the right choice for the secure transfer.

4. Vignere Cipher

This is a kind of substitution cipher processing with the given keyword for the similar encryption and decryption process. Substitute the keyword with the input and subtract the two numerical values and get an answer in the subtraction. The equivalent value of the numerical number helps to identify the secret message.

These are the famous cipher techniques that help in the transformation of secure messages, and it acts as a bridge between the sender and the receiver. Rather than this substitution cipher, another advance methodology is transposition cipher. This is also a key to transfer the secret message. Additionally, there are cybersecurity that is to protect and prevent cyber-attacks.
