Cryptography and Encryption Basics - II


RC4 



RSA cryptography



Key Exchange:


Diffie-Hellman Key Exchange:


Key Escrow;


Trust Module:


Public Key Infrastructure (PKI) and Digital Certificates:

 
Hash Functions:


Digital signature: 

Digital signatures are related to encryption, but do not mean a message is in encrypted. A digital signature is a verification of the authenticity of the digital message or documents. The digital signature makes sure that the message was created by a known sender, and the message was not altered in transit.

Cryptography and Encryption Basics I What is encryption Encryption is the process of encoding a message or information in such a way that only authorized parties can access it and those who are not authorized can't.  Converts information from plain text into encrypted ciphertext. But how...? Encryption used algorithm! An algorithm is a procedure that the encryption process follows. The specific algorithm is called the ciper or code. there are many types so encryption algorithms. The encryption's goal and level of security determine the most effective solution. Triple DES, RSA and Blowfish are some examples of encryption algorithms or Ciphers. What is Decryption? Decryption is the process of taking encoded or encrypted text or other data and converting it back into text that you or the computer can read and understand.  converts information from encrypted ciphertext into plain text  Basic Example  Private key vs Public Key Private Key (symmetric key): This means that ...
