One, asymmetric encryptionAsymmetric encryption has a set of key pairs, one is public, anyone can obtain, called the public key;One is self-preservation and strictly confidential, called the private key.The rules are as follows:by someone A the public key encrypted message, only by the A the private key is decrypted;by A The private key encrypts the message, only by the A decryption of the public key. sender, the receiver holds the public key / privat

This document describes seven methods: I. Simplest encryption and decryption Ii. Use the Escape Character "\" 3. Use the script encoder produced by Microsoft for encoding (simple decoding) 4. Add any NUL null characters (hexadecimal 00 h) (self-created) 5. Useless content and line feed space tab Method Vi. Self-write decryption Function Method 7. Misuse (self-developed) During webpage creation (in fact, webpage Trojans), the most worrying thing is
