Computer worms are programs that reproduce, execute independently, and travel across network connections. The key difference between a virus and worm is the manner in which each reproduces and spreads. A virus is dependent upon the host file or boot sector and the transfer of files between computers to spread, whereas a computer worm can execute completely independently and spread on its own accord through network connections.
The security threat from worms is equivalent to that of viruses. C

AES (Advanced Encryption Standard) is the currently employed specification for encrypting electronic data by the United States National Institute of Standards and Technology, or NIST. AES was selected as the U.S. standard for encryption of unclassified information in 2001 supplanting DES which had been the U.S. standards for a number of years (since 1977). AES is based on the Rijndael cipher that was developed by Belgian mathematicians Vincent Rijmen and Joan Daemen. Their proposal was evaluated

PDF documents can utilize two passwords:
Password to open
Password to restrict printing and editing
Password to Open
The Password to open requires a user to enter a password to view the document.

A buffer overflow occurs when a computer application attempts to assign data to a data structure past the point that the structure is designed to store information. In the classic case, a buffer is a sequential memory section that is assigned to contain information. The type of information can vary from an array of integers to objects. When information is stored outside the allocated block of memory, the program can crash or computer malware can infect it.
Why are Buffer Overflows Dangerous?

GPG, or GNU Privacy Guard, is a free replacement and competing product for PGP (Pretty Good Privacy). The project is a data encryption and decryption application which provides end-users with a cryptographic privacy and authentication system for communicating electronic data. GPG can be used to sign, encrypt, and decrypt text, for email, files, directories, and entire disk partitions. It is primarily intended to increase the security of email communications similar to PGP; however, is a complete

Cryptanalysis is the science of making encrypted data unencrypted.
Cryptanalysts
Practitioners of cryptanalysis are known as cryptanalysts.
Cryptanalysis in Context
A cryptographer will use cryptography to convert plaintext into ciphertext and a cryptanalyst will use cryptanalysis to attempt to turn that ciphertext back into plaintext.
Both the cryptographer and the cryptanalyst are cryptologists. Cryptography and cryptanalysis are the two sides of cryptology.

Most web browsers store web pages and images that we browse on the Internet. The web browsers cache (meaning, temporarily store) these files for a short time in your computer.
If we revisit a pre-visited web page while these files are still in the cache, the web browser retrieves the files from the disk cache instead of getting these files from the web site. This can significantly speed up web browsing, but it may not render the updated web page in some cases.
The web browser cache can cau
