types of cryptography for example symmetric keys or shared- secret cryptography, is when you use the same key to both encrypt and decrypt a message. The most common form of symmetric key cryptography is the data Encryption standard. The second type of cryptography is asymmetric key cryptography, two keys are needed. A message encrypted using one key can only be decrypted using the other and vice versa. One key is called public key and the other is called the private key. Cryptosystem disguises messages

using symmetric encryption and cryptographic hash md5. The symmetric is old and the best know the technique used it to secure the data and encrypt and decrypt the message by using a private key which can be a number, word, or just letters. The hash md5 is a kind of of security mechanism that produces a message digest, hash value or the checksum value for a specific data object. As mentioned above, symmetric encryption can be very helpfully solution by acting as a supplementation of encryption data

1. Data Encryption Standard (DES): A predominant algorithm for the encryption of electronic data. It was influential in the advancement of modern cryptography in the academic world. 2. Rivest, Shamir and Adleman (RSA) encryption algorithm: Internet encryption and authentication system that uses an algorithm. It is most commonly used encryption and authentication algorithm used. 3. Triple DES: A block cipher, which applies the data encryption standard cipher algorithm three times to each data block

Encryption changes plain text into unreadable text using an algorithm. It’s a process of hiding information so that outside sources cannot see or manipulate it. The most secure web encryption is 128-bit. It uses a longer sequence of bits to increase strength of encryption by offering an additional 88 bits of key length. This encryption uses a public key during the encryption process and a different private key for the decryption process. Most all providers now use 128 bit encryption which means

both technical concerns, such as the security of a credit card number or banking information, and legal concerns for holding individuals responsible for their actions such as their purchases or sales over the Internet. Issuance and management of encryption keys for millions of users will pose a new type of challenge. While some technologies have been developed, only an industry-wide effort and cooperation can minimize risks and ensure privacy for users, data confidentiality for the financial institutions

There are two types of cryptography. Secret key cryptography is also known as symmetric key cryptography. With this type of cryptography, both the sender and the receiver know the same secret code, called the key. Messages are encrypted by the sender using the key and decrypted by the receiver using the same key. This method works well if you are communicating with only a limited number of people, but it becomes impractical to exchange secret keys with large numbers of people. In addition, there

Relate Windows Encryption and Hashing to Confidentiality and Integrity Course Name and Number: Student Name: Instructor Name: Lab Due Date: Overview This lab demonstrated how hashing tools can be used to ensure message and file transfer integrity and how encryption can be used to maximize confidentiality. Common hashing and encryption tools, including MD5, SHA1, and GnuPG, were used. You used GnuPG to generate both a public and private key and a secret key for encryption only. Lab Assessment
