pgp encryption for android

This article summarizes the Android programming encryption algorithm. Share to everyone for your reference, specific as follows: The BASE64 encryption algorithm of the Android common encryption algorithm: Package Com.long; /** * Copyright (C) The

Add salt The way to add salt is also varied String+key (salt value key) and then MD5 encryption Use string plaintext hashcode as salt, then MD5 encryption Randomly generates a string of strings as salt and then MD5 encryption public static String md5(String string, String slat) { if (TextUtils.isEmpt

Linux Kernel (Android) encryption algorithm Summary (iii)-Application call Kernel cryptographic algorithm interfaceThe method of how to invoke interfaces in the kernel is described.This section is mainly about how to invoke the AES encryption algorithm of the Android C + + application calling OpenSSL.Crypt_ssl.c#includ

In Android, you need to encrypt various kinds of data, such as the data encryption of user's SMS backup, password encryption of user account login and encryption which is applied to the server connection to pass important data, which is very useful.Here is an introduction to MD5 encryption:Case-driven: 123

Objective Non-encrypted grab packets Packet capture after encryption Basic requirements and concepts AES algorithm AES Fundamentals and Algorithmic flow AES Algorithm Flow RSA algorithm Fundamentals and flow of RSA algorithms RSA algorithm Implementation process AES and RSA combined data encryption scheme

[Android development experience] a safer algorithm than DES encryption-3DES encryption algorithm, android3des Reprinted please indicate the source: http://blog.csdn.net/zhaokaiqiang1992 In the previous article, we discussed the DES algorithm and learned how to ensure the consistency of encryption and decryption results

Objective: For the SHA Safe hashing algorithm, before how to use, just stay in the heard of the stage, today in the picture Caching framework Glide source code found that its cache key is not MD5 encryption algorithm, but SHA-256 encryption algorithm, this just reminded me of curiosity, so take advantage of the evening nothing, To learn. Several other encryption
