Principle and usage analysis of RSA encryption and decryption algorithm based on PHP
This paper describes the principle and usage of RSA encryption and decryption algorithm of PHP. Share with you for your reference, as follows: Recently, because of the need of work, Alipay has to pay for the related knowledge, because Alipay has applied the RSA encryption mechanism. 1. Generate public and private keys In order to […]

Analysis of DSA and RSA asymmetric encryption of OpenSSL under Linux
In the daily system management work, we need to do some encryption and decryption work, we can complete a lot of requirements through OpenSSL toolkit!1. OpenSSL RSA encryption and decryptionRSA is an asymmetric encryption method based on the product of large prime numbers in number theory, which uses public and private keys for encryption and […]

Rare C ා RSA algorithm
At present, the most popular RSA encryption algorithm can crack the encrypted information only when the public key and private key are owned at the same time. The emergence of RSA encryption algorithm is conducive to data security transmission 1. The RSACryptoServiceProvider class in C ා allows you to generate XML format public key and […]

RSA of golang encryption and decryption (with PHP)
Brief history of RSA encryption algorithm RSA was proposed by Ron Rivest, ADI Shamir and Leonard Adleman in 1977. All three of them worked at MIT at that time. RSA is a combination of the first letters of their surnames. RSA encryption algorithm principle All the friends who have studied algorithm know that the algorithm […]

Detailed explanation of RSA encryption and decryption in C
1. RSA encryption and decryption — use public key encryption and private key decryption public class RSATool { public string Encrypt(string strText, string strPublicKey) { RSACryptoServiceProvider rsa = new RSACryptoServiceProvider(); rsa.FromXmlString(strPublicKey); byte[] byteText = Encoding.UTF8.GetBytes(strText); byte[] byteEntry = rsa.Encrypt(byteText, false); return Convert.ToBase64String(byteEntry); } public string Decrypt(string strEntryText,string strPrivateKey) { RSACryptoServiceProvider rsa = new RSACryptoServiceProvider(); rsa.FromXmlString(strPrivateKey); […]

C ා RSA docking Java RSA mode code instance
In C ා, XML is used to load through the fromxmlstring attribute, while in Java, the parsed PEM string is used. In short, reading the information in the certificate is nothing more than a conversion method problem /// <summary> ///C ා using Java’s public key for RSA encryption utf8 encoding to encrypt data by parsing […]

Youth Upgrade on PHP Encryption and Decryption (API Security Enhancement Part II)
Why does the title always carry the keyword “API security“? Because I think I’d like to. In fact, this article and the last one can be regarded as the followup of “Introduction to Lazy Man about PHP Encryption and Decryption (API Security Enhancement Part 1)”, but the focus is on security. If you haven’t read […]

C# Encrypts and decrypts files using RSA
In this paper, we share the specific code of C# using RSA to encrypt and decrypt files for your reference. The details are as follows. Encryption code: // Encryption code, note that it will overwrite the original file, which contains my public key, you need to remember to overwrite my public key when you use […]

RSA of Asymmetric Algorithms
Find a formula that’s easy to forward and hard to reverse. $$ m^{x} \equiv y\pmod n$$ Assuming that $m$, $n$are known positive integers, it is easy to calculate $y $with the knowledge of $x $while it is difficult to estimate $x $with only $y $ Here we have to introduce a formula.Phi function is denoted […]

Asymmetric Encryption of Encryption Algorithms
The previous article introduced the principle of symmetric encryption, but its biggest problem is that the encryption and decryption keys are the same, and can not guarantee that the key can be safely delivered to both sides, even if it is safely delivered to both sides, there will inevitably be “undercover” inside. Asymmetric encryption Since […]

Using RSA to Encrypt Frontend Public Key and Decrypt Backend Private Key
In the project, users need to encrypt their usernames and passwords when they log in. RSA asymmetric encryption is chosen here. Public key private key: OpenSSL public key private key (Node crypto module restriction) Front end: jsencrypt library encryption Backend: Node crypto module Using OpenSSL to generate public key and private key Linux generates public […]
