In web development, using RSA public Key system to make Ukey, file certificate Landing, the common practice is: the browser side of the use of C + + ActiveX control, using C + + Third library OpenSSL for RAS add-sign operation, The client's signature is checked by Java on the server side. This involves the process of verifying the identity of the client with the interactive plus check between C + + OpenSSL and Java.If you find my side of the article t

JS to PHP uses the RSA Algorithm for encrypted communication, jsrsa
We usually submit the user login form, and the user name and password are POST directly to the backend in plain text, which is easy to be listened to by others.
When I do rsa on js, I feel that jsencrypt is well encapsulated, but I still encountered some pitfalls in use, So I entered the code to fill in the pitfalls ~

RSA encryption algorithm is the most influential public key encryption algorithm, it can resist the most known password attacks so far.What are the applications of RSA encryption algorithms? Here's a case for database authentication.When using the data set for authentication, the password exists in the database, the authentication user entered the password and the password in the database is the same authen
Subject to the Web page source code exposure, so the traditional symmetric encryption scheme and encryption key will be exposed in the JS file, the same can be decrypted.At present, the better solution is to use HTTPS for the entire Web page or user login and other key links.Another solution is to encrypt through Rsa.RSA is an asymmetric encryption, that is, the client encrypts through the public key, and the server decrypts it through the private key . RSA
directly. This is referred to as the "Diffie-hellman Key exchange Algorithm". This algorithm inspires other scientists. It is recognized that encryption and decryption can use different rules, as long as there is a corresponding relationship between the two rules, so that the direct transfer of the key is avoided.This new encryption mode is called an "asymmetric encryption algorithm".
(1) Party B generates two keys (public and private). The public key is public and can be obtained by a
First, the introduction: RSA encryption algorithm is the most commonly used asymmetric encryption algorithm, CFCA in the certificate service cannot leave it. RSA is the first more sophisticated public key algorithm that can be used for both encryption and digital signatures. This algorithm has withstood many years of in-depth password analysis, although the password analyst can neither prove nor deny the se
A brief history of RSA encryption algorithms
RSA was presented in 1977 by Ronald Leevist (Ron rivest), Adi Samor (Adi Shamir) and Lennard Adman (Leonard Adleman). All three of them were working at MIT. RSA is the beginning of their three-person surname together with the letter of the composition.
The principle of RSA

RSA is currently the most influential public-key encryption algorithm, it can resist the most known password attacks so far, has been recommended by the ISO public key data Encryption standard.
Only short RSA keys today can be broken by brute force mode. Until 2008, there was no reliable way to attack the RSA algorithm in the world. As long as its key length is
