To see if a package is installed: dpkg-lSteps:1th step: Create SSH Key. In the user home directory, see if there is no. ssh directory, if there is, then look at this directory there are no id_rsa and id_rsa.pub these two files, if already have, you can skip to the next step. If not, open the shell and create SSH Key:Ssh-keygen-t rsa-c "[Email protected]"If all goes well, you can find the directory in the us

RSA public Key cryptography was developed in 1977 by Ron Rivest, Adi Shamirh and Lenadleman (Massachusetts Institute of America).The algorithm's name is also their three person initials, the RSA algorithm is based on a very simple number theory fact:Multiplying the two large primes is easy, but it is extremely difficult to factorization the product, so the produc

With regard to RSA, my understanding is:By definition, the public key can be interchanged.The problem is the common implementation inside, the data structure or file that holds the "private key", in addition to the pair of numbers necessary for the private key, there is additional information (enough to calculate the p

Finding discrete logarithms is very difficultRSA is the first letter of the surname of Ron Rivest/adi Shamir/leonard Adleman.RSA can be used for public key cryptography and digital signatures.RSA encryption: Ciphertext = plaintext EMODN (e and N are public keys)RSA decryption: plaintext = ciphertext DMODN (d and n are private keys)The decryption of RSA:Brute force: The difficulty of brute force will increas

Public and private can be generated using the OpenSSL tool.In a Windows environment, you can download the OpenSSL tool (http://www.openssl.org/related/binaries.html) yourself.In a Linux environment, you can install the OpenSSL toolkit (in Ubuntu, for example, execute sudo apt-get install OpenSSL).Under Windows environment, open the Openssl.exe under the OpenSSL installation directory bin file. In a Linux environment, you run OpenSSL directly in the terminal.1) Generate

If you want to use OpenSSL on Ubuntu, you need to install it first, the command is as follows:sudo apt-get install OpenSSLYou can use OpenSSL when the installation is complete.The first step is to enter OpenSSL's interface and enter OpenSSL at the command line;1) Generate RSA private key:Genrsa-out RSA_PRIVATE_KEY.PEM 1024The command generates a 1024-bit private key, which generates a successful interface a
