这个时代是搬运工的年代,很多好东西,有价值的东西,大量的被copy,这样就没有价值了,所有我们针对源码的加密还是有必要去做的。
一个简单的php加密解密函数:- function encode_pass($tex,$key,$type="encode"){
- $chrArr=array('a','b','c','d','e','f','g','h','i','j','k','l','m','n','o','p','q','r','s','t','u','v','w','x','y','z',
- 'A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P','Q','R','S','T','U','V','W','X','Y','Z',
- '0','1','2','3','4','5','6','7','8','9');
- if($type=="decode"){
- if(strlen($tex)<14)return false;
- $verity_str=substr($tex, 0,8);
- $tex=substr($tex, 8);
- if($verity_str!=substr(md5($tex),0,8)){
- //完整性验证失败
- return false;
- }
- }
- $key_b=$type=="decode"?substr($tex,0,6):$chrArr[rand()%62].$chrArr[rand()%62].$chrArr[rand()%62].$chrArr[rand()%62].$chrArr[rand()%62].$chrArr[rand()%62];
- $rand_key=$key_b.$key;
- $rand_key=md5($rand_key);
- $tex=$type=="decode"?base64_decode(substr($tex, 6)):$tex;
- $texlen=strlen($tex);
- $reslutstr="";
- for($i=0;$i<$texlen;$i++){
- $reslutstr.=$tex{$i}^$rand_key{$i%32};
- }
- if($type!="decode"){
- $reslutstr=trim($key_b.base64_encode($reslutstr),"==");
- $reslutstr=substr(md5($reslutstr), 0,8).$reslutstr;
- }
- return $reslutstr;
- }
- $psa=encode_pass("phpcode","taintainxousad");
- echo $psa;
- echo encode_pass($psa,"taintainxousad",'decode');
