Everyday information gets into the wrong hands. This can lead up to millions of dollars lost for a company and its reputation in this global environment. It only by knowing the different encryption methods you hope to protect your reputation and assets. I will discuss a possible solution to protect your information and explain the advantages and disadvantages of asymmetric or symmetric keys.
Everyone is worried about data protection these days; especially big companies. Furthermore, by not having good data protection companies can get their reputations cripple or cease to exist in the global economy. A lot of big organizations relay on data encryption to protect their client information or sensitive information from rivals. The two big names in that encryption process are Asymmetric and Symmetric. Asymmetric and Symmetric both have their disadvantages and advantages.
Asymmetric is known as public key encryption. This method of encrypting messages makes use a public key and a private key. The public key is made publicly available and is used to encrypt messages by anyone who wishes to send a message to the person that the key belongs to. The private key is kept secret and is used to decrypt received messages (Arthur Conklin, 2010). There are some praiseworthy advantages of asymmetric encrypting. The first advantage is it convince. Everyone key is made public and the private keys are kept secret which individual will use to decrypt. The second advantage is that it allows for message authentication. The public key that person creates allows the use of a digital signature. This permits the recipient of a message to verify that the message is truly from the person who signed sent the information. Third it has detection of being alte...

...and not the others. Also with the communication between the two entities it will be easier because of the duality. It will make keep track of keys easier and you don’t have to rely on third party. If you do not adapt any of his method you will be left out you will be left behind in this global environment.

What is encryption? Encryption is a technological technique that protects and secures the transfer of plain text information between two sources through the use of the internet. This is done by rearranging the text using a mathematical algorithm that renovates the message into an indecipherable form, which can only be unlocked and translated with a use of a key. The strength of the encryption key is measured by its length, which is determined by the number of bits and by the type of encryption program.
Asymmetric Encryption is used to protect the data while in movement. Asymmetric Encryption is also known as Public Key Encryption. It uses two related keys, a public key and a private key which is not shared with anyone. This pair of keys are developed by mathematical methods which can be solved in one direction. So anyone can encode a data using the public key but only the user with a private key can decode that specific data. The length of Asymmetric Key Encryption is normally 1024 or 2048 bits. However, in Asymmetric framework the keys with smaller than 2048bits are considered as not safe to use.
Today’s businesses and organizations need privacy. They need to keep their employee’s information, trade secrets, financial records, and many other sensitive documents that cannot be shown to the public. To do this, these organizations use encryption. Encryption is using an irreversible program to turn a file into gibberish. To translate the gibberish back to the original contents of the file, you must use a decryption program and provide a password. This is so the program can decrypt the file correctly. This encryption is what prevents cybercriminals who happen to get a hold of any files from looking at file contents. To the cybercriminal, encrypted files are completely useless unless he can figure out how it was encrypted. In order to decrypt the file, the cybercriminal must first find a series of steps that can decrypt the file over and over again: an algorithm.

Cryptography is definitely become a more mainstream topic today. Almost every device in this world is connected to the internet and sharing information. At the same time of the increasing of number in the device, the number of sensitive data in the information shared between devices, application, and server is also increasing in a larger scale. That information must be protected, so that the sensitive data will remain private.

Despite the numerous advantages offered by cloud computing, security is a big issue concerned with cloud computing. There are various security issues and concerns associated with cloud computing, among them being phishing, data loss and data privacy. There are different mitigation measures that cloud pioneers are currently using to ensure data stored in the cloud remain secure and confidential as intended. Encryption is one mitigation method used to ensure security in cloud computing. According to Krutz and Vines (2010), encryption involves coding of the data stored in the computing cloud such that hackers cannot gain access to the data. Data encryption seems to be the most effective method of ensuring security in computing (Krutz and Vines, 2010). However, it is of paramount importance to note that encrypted data is usually difficult to search or perform various calculations on it.

The length of the key for the encryption can vary from being very short to extremely long, and the length of the message being encrypted. The protection of data being transferred between ATMs and the bank, and the use of cell phones, is the most common everyday encounter with encryption. To encrypt and decrypt information, a cipher is used. In a cipher, there is a set of well-defined steps that can be followed to encrypt and decrypt messages.
In this era when the Internet provides essential communication between tens of millions of people and is being increasingly used as a tool for security becomes a tremendously important issue to deal with, So it is important to deal with it. There are many aspects to security and many applications, ranging from secure commerce and payments to private communications and protecting passwords. One essential aspect for secure communications is that of cryptography. But it is important to note that while cryptography is necessary for secure communications, it is not by itself sufficient. Cryptography is the science of writing in secret code and is an ancient art; In the old age people use to send encoded message which can be understand by the receiver only who know the symbolic and relative meaning of that encoded message .The first documented use of cryptography in writing dates back to circa 1900 B.C. Egyptian scribe used non-standard hieroglyphs in an inscription. After writing was invented cryptography appeared spontaneously with applications ranging from diplomatic missives to war-time battle plans. It is no surprise, then, that new forms of cryptography came soon after the widespread development of computer communications. In telecommunications and data cryptography is necessary when communicating in any untrusted medium, which includes any network, particularly the Internet [1].Within the context of any application-to-application communication, there are some security requirements, including:
Encryption plays a big role with the safety now in day because everything is now done digitally and it helps it be more confidential. This prevent “hackers”, well it’ll be difficult for them to open the gateway to get all the confidential information someone wanted to hide. The disadvantage is that drug dealer and sex trafficker can make money by making the encryptions and that’s where they have people wire the money and it’s untraceable unless cracked. Encryption is playing a big role in the world because people use it for protection in their important usage or for government purposes and others use it for the dark web to transfer their illegal money to be untraceable.
