Because the project needs to transmit the user password, in order to ensure security, we need to use RSA encryption, So we learned how to use
The use of phprsa encryption and decryption is detailed, and the use of rsa encryption and decryption is detailed. Explanation of use of phprsa encryption and decryption, and explanation of use of rsa encryption and decryption 1.
RSA encryption
RSA is the most influential public-key encryption algorithm, and RSA is the first algorithm that can be used both for data encryption and digital signature. The algorithm is based on a very simple number theory fact: it is easy to multiply two large primes, but it is extremely difficult to factorization the product, so you can expose the product a
). This formula can also be expressed as d≡e-1 mod f (n)To explain here, ≡ is the symbol of the same remainder in number theory. In the formula, the left side of the ≡ symbol must be the same as the right side of the symbol, which means the results are identical. Obviously, no matter what value f (n), the 1 mod f (n) on the right of the symbol results in 1, and the result of the symbol's left D and E is also equal to 1 after the modulo operation. This needs to calculate the value of D, so that t
Both the rsacryptoserviceprovider and dsacryptoserviceprovider constructors can specify a cspparameters struct. Using this cspparameters struct, We can customize the CSP local storage name (that is, the key container: keycontainer) of the asymmetric encryption algorithm. This container is saved in the Windows user configuration file by default.
If you want to store the key within the computer range (rather than the user range), you can use the usemach
1, encryption and decryption of the first step is to generate a public key, private key pair, the private key encrypted content can be decrypted through the public key (in turn can also)
Download the open source RSA key generation tool OpenSSL (usually the Linux system comes with the program), unzip it to a separate folder, go into the bin directory, and execute the following command:
Copy Code code as follows:
OpenSSL genrsa-out Rsa
Because the project needs to transfer the user password, in order to secure the need to use RSA encryption, so learn the next RSA encryption in iOS application. About the history and principles of RSA, the following two articles are very clear: http://www.ruanyifeng.com/blog/2013/06/rsa_algorithm_part_one.html/http Www
Use digital signature RSA or DSA to implement ssh between two linux machines without the user name and password, rsassh
To enable two linux machines to use ssh, the user name and password are not required. Therefore, the digital signature RSA or DSA is used to complete this operation.

When the PHP server interacts with the client and provides an open API, it is often necessary to encrypt the sensitive part of the API data transfer, at which point RSA Asymmetric encryption can be used, and an example to illustrate how to use PHP to encrypt and decrypt data.1, the first step of encryption and decryption is to generate a public key, a private key pair, the private key encrypted content can
Use Git's child shoes should be ID_RSA secret key is not unfamiliar, must use GitHub bar, the generation Id_rsa is very easy:
Ssh-keygen-t rsa-c "$your _email"
By default, this secret key is generated in your account in the. SSH directory generates ID_RSA files, corresponding to a id_rsa.pub public key file,
$ ssh-keygen-t
