Encryption is a form of cryptography that “scrambles” plain text into unintelligible cipher text. Encryption is the foundation of such security measures as digital signatures, digital certificates, and the PKI that uses these technologies to make computer transactions more secure. Computer-based encr...
As you discovered in the previous unit, cryptography is the art of obscuring the meaning of a message to everyone but the intended recipient. This requires the plaintext message to be transformed into ciphertext. The mechanism that enables this is called encryption. The met...
CNG allows for more agile encryption, where encryption and hashing algorithms that are supported on the host computer can be specified for use during the document encryption process. CNG also allows for better extensibility encryption, where third-party encryption modules can be used....

Public-key cryptography, asymmetric form of cryptography in which the transmitter of a message and its recipient use different keys (codes), thereby eliminating the need for the sender to transmit the code and risk its interception. It is commonly used i
Encryption is just one form of cryptography.It is an operational process that uses math and algorithms to encode plaintext more efficiently and in more complex ways. People use encryption specifically to prevent unauthorized use of data. How does encryption work?
The above process can be directly applied for the RSA cryptosystem, but not for the ECC. The elliptic curve cryptography (ECC) does not directly provide encryption method. Instead, we can design a hybrid encryption scheme by using the ECDH (Elliptic Curve Diffie–Hellman) key exchange scheme to...
