To put it bluntly, here we mainly describe some encryption and decryption algorithms implemented by Java, and finally introduce digital certificates. For example, the basic one-way encryption algorithm: Base64 strictly speaking, it belongs to the

From: http://snowolf.iteye.com/blog/379860 Encryption and decryption were once an important component of my graduation project. After many years of work, it was too simple to recall the encryption and decryption algorithm at that time.To put it

Beginning to those basic encryption is not very skilled, and then summed up some, wrote a test: Support Base64, MD5, MAC, HMAC encryption, long story short, we all prefer to understand, look at the code!The format of the transmission UTF-8 ...
