Public key cryptography: The key is a pair of children appearPublic key: public to all; PubKeyPrivate key: Keep it for yourself, must ensure its privacy; secret keyFeatures: Data encrypted with the public key can only be decrypted with the private

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
