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

The simple Java encryption algorithm is:BASE64 strictly speaking, it belongs to the encoding format, not the encryption algorithmMD5 (Message Digest algorithm 5, Information Digest algorithm)SHA (Secure Hash algorithm, security hashing

The full name of MD5 is message-Digest algorithm 5. Message-digest refers to the hash transformation of the message. It is to convert a byte string of any length into a long big integer. MD5 converts a "Byte string" of any length into a large

[Preface]This article briefly introduces the concepts related to encryption technology, and finally summarizes the existing encryption technology in java as well as its usage and examples. [Simple encryption] 1. Simple concept Plaintext: the

The RSA public Key cryptography algorithm was introduced in 1977 by Ronald Leevist (Ron rivest), Adi Samor (Adi Shamir) and Lennard Adman (Leonard Adleman). At the time, all three of them worked at MIT. RSA is the first letter of their three

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
