RsaAsymmetric encryption, public key encryption, private key decryption, and vice versa. Because of the need of large number of the algorithm such as the exponentiation, running speed is slow, not easy to implement hardware.Usually the length of the private key is 512bit,1024bit,2048bit,4096bit, the longer the length, the more secure, but the slower the key generation, the more time it takes to decrypt the

iOS system itself with the RSA encryption class has a feature, that is, encryption is one-way, that is, only public key encryption-> private key decryption, vice versa will be an error. So many friends will have this situation, in the iOS client with public key encrypted data to the server side with the private key to

1. MD5 encryption, often used to encrypt user name passwords, when the user is authenticated. protected byte[] encrypt(byte[] obj) ...{   try ...{     MessageDigest md5 = MessageDigest.getInstance("MD5");       md5.update(obj);     return md5.digest();   } catch (NoSuchAlgorithmException e) ...{     e.printStackTrace();   } }

The data is encrypted for security reasons in the project, and RSA is used to encrypt it.Summarized as follows:Features: Public key encryption private key decryption, private key signature public key authentication, public key is generated through the private key.Advantages: Asymmetric encryption, high security;Disadvantage:
