是否有任何人知道将与所有这些平台合作签署算法。
服务器将通过 Java方案生成一个公私营钥匙。 因此,客户应用(移动电话)需要从服务器上发出使用私人钥匙(公共钥匙储存在装置上)签字的信息。
然而,以下价值观与安妮和 Java合作,我不清楚它们如何与其他平台合作。
//For the server signed message
public static final int RSA_KEY_SIZE = 2048;
public static final String SIGNATURE_ALGORITHM = "SHA256withRSA";
public static final String RSA = "RSA";
public static final String PROVIDER = "BC"; //Bouncy Castle
//For hashing sensitive data over the network
public static final String SECURE_RANDOM_ALGORITHM = "SHA1PRNG";
You incorrectly understand asymmetric cryptography. To encrypt message, server should use public key of the client, and with his private key client will be able to decrypt message. What is done with RSA private key is called signing . In case you need to use encryption with only one hard-coded key, you can use symmetric cryptography (for instance, AES).
