Hash functions
It is possible to use cryptographic methods to not only ensure data privacy, but also check its integrity. As a rule, integrity is checked with the help of the so-called “checksum”. Specialists in the field of data encryption and communications theory have developed a lot of algorithms that calculate the checksum of transferred or stored [...]
About Twofish
Twofish is a symmetric-key block cipher with a block size of 128 bits and a key size of up to 256 bits. This algorithm was one of the five finalists of the AES public contest that was announced by National Institute of Standards and Technology (NIST) in 1997. The cipher is the further development of [...]
What is AES?
Advanced Encryption Standard (AES), also known as Rijndael, is a block cipher adopted as an encryption standard by the U.S. government. AES is a symmetric-key algorithm that was designed to replace its outdated predecessor DES (Data Encryption Standard). This algorithm appeared as a result of the public competition announced by the National Institute of Standards [...]
How to choose a strong password
It has been known for long that even the securest system has its weak sides. And, as a rule, it is not even its technical peculiarities (for example, encryption algorithms) that cause it to be hacked, but just casual carelessness of people who use it. It is very often due to this so-called human factor [...]
