问题 I\'m creating a public internet facing website which contains the email address of their salespeople. What kind of programming options do I have to generate the \"mailto\" and display the email from that address but limit the spambots from picking up the address? 回答1: Recaptcha has an excellent capture based email protection. You can see it implemented at the bottom of any page in my website using the Site Feedback link. 回答2: I know that Facebook does it by displaying an image instead of text

问题 In Java in the equals(Object o) method I can access the private variables of the passed in object without going through its public getters. public boolean equals(Object o){ ... MyObject other = (MyObject)o; return getProp() == other.prop; } How\'s that? 回答1: Private data is accessible by any instance of that class, even if one instance of class A is accessing the private members of another instance of A. It's important to remember that that access modifiers (private, protected, public) are

问题 A different question, i.e. Best .NET obfuscation tools/strategy, asks whether obfuscation is easy to implement using tools. My question though is, is obfuscation effective? In a comment replying to this answer, someone said that \" if you\'re worried about source theft ... obfuscation is almost trivial to a real cracker \". I\'ve looked at the output from the Community Edition of Dotfuscator: and it looks obfuscated to me! I wouldn\'t want to maintain that! I understand that simply \'cracking

问题 I have enabled the -Wstack-protector warning when compiling the project I\'m working on (a commercial multi-platform C++ game engine, compiling on Mac OS X 10.6 with GCC 4.2). This flag warns about functions that will not be protected against stack smashing even though -fstack-protector is enabled. GCC emits some warnings when building the project: not protecting function: no buffer at least 8 bytes long not protecting local variables: variable length buffer For the first warning, I found

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 6 years ago . I release a bunch of tools for free, but recently I have began to sell an application, that has private research, and people have been able to get my source code, and one person publically released my entire source. I spent a lot of time on this program, just to have someone crack it, and release my entire

问题 It is currently said that MD5 is partially unsafe. Taking this into consideration, I\'d like to know which mechanism to use for password protection. This question, Is “double hashing” a password less secure than just hashing it once? suggests that hashing multiple times may be a good idea, whereas How to implement password protection for individual files? suggests using salt. I\'m using PHP. I want a safe and fast password encryption system. Hashing a password a million times may be safer,
