RSA algorithm is an asymmetric encryption algorithm, which is often used for encrypting data transmission. If the number digest algorithm is combined, it can also be used for file signing.This article discusses how to use RSA to transfer encrypted data in iOS.This article environment Mac OS OPENSSL-1.0.1J, OpenSSL requires a 1.x version and is recommended for use with [homebrew] (http://brew.sh/) installation. Java 8 RSA FundamentalsRSA encrypts the data using the "key pair

What is private key cryptography technologyThe private key (symmetric key), also known as the symmetric key. The key encryption algorithm uses the same key for encryption and decryption. It has the advantage of very fast encryption and decryption, but it is difficult to distribute and manage keys. The sender and receiver of the information must specify the same key. Therefore, key communication must be performed, which usually requires a more secure channel to transfer the key. In addition, each

It is well known that most iOS code is generally not encrypted, because iOS apps are generally released via AppStore, and Apple's system is hard to break, so code hardening in iOS is generally a thankless task. Everything is an exception, regardless of iOS, ADR or JS, the purpose of encryption is for code security, although now open source, but regardless of individual developers or manufacturers have the need to protect code security, so iOS code to strengthen the survival of the soil.
