Encryption software scrambles information for secure communication or to conceal valuable data. It incorporates knowledge from math, stats, computer science, and engineering. Hackers use it to gain access to computers. Encryption software is available for purchase or free download and can be governed by national laws.
Encryption software is a type of computer program typically used to scramble information. This may allow communication to be transferred between the parties securely or allow valuable information to be concealed. Encryption software has become much more common since the emergence of the Internet. Some of its specific applications include encrypting ATM and credit card numbers, masking email passwords, and maintaining overall network security. The term encryption sometimes refers to deciphering information, as opposed to encrypting it.
In order to produce the best possible encryptions, knowledge from four different fields are typically incorporated into encryption software: mathematics, statistics, computer science, and engineering. This software generally uses some type of encryption, which is an algorithm used to scramble information. Ciphers are considered more complicated than codes, and the two are distinguished by cryptographic experts. This is because the codes use a larger codebook, which is referenced when interpreting a message. Conversely, the encryption algorithm is more diverse and generates more complex encryption patterns.
For personal computer users, encryption software can perform many different tasks. For example, e-mail encryption programs may allow a person to send messages with encrypted content to other e-mail users. All that is needed is the common key, or algorithm, to decrypt these messages, which is usually part of the encryption software.
Hackers often use encryption software to gain access to other computers. For example, some programs can find out the passwords of various networks. Hackers can also use software, such as file shredders, to gain access to a computer and then destroy all files on it, changing the code and making recovery impossible.
Many encryption software is available for purchase or free download. Programs can vary in the quality of the algorithm and encoding they use. Some software may be specifically designed to decode or decipher information.
There are also types of encryption software called virtual keyboards. This software prevents key logging, which is a program that tracks common keystrokes used in typing passwords and credit card numbers. The virtual keyboard, as the name suggests, sets up a “fake” keyboard that alters the keys pressed within it, so that a keylogger will receive different information than the actual password entered.
Encryption software is often governed by national laws. For example, some countries do not allow their export or import. In some cases, a permit may be required to ship software internationally.
