SHA series encryption, SHA512 security is safe, but the number of bits is too long, very few people use it to encrypt the password, below I briefly introduce SHA and some variant encryption (SHA512 will also use) program with internationalization, are used UTF-8 encoding format (if there are more than I have to write the same encryption method to get the ciphertext different, if you want to question, first put the code to see, different codes produce ciphertext is different) provide another way of thinking (next stage): In the process of multiple encryption code repeatedly change ... Think about it. ~ This is SHA-1 encryption, and MD5 the same maybe someone will ask, that for loop why not? I'm using the officially provided method, for loop that generally only in the internal byte deformation or just learn to use If you do not know what I said,,,, look at this diary, there is an explanation: http://user.qzone.qq.com/ 1054186320/blog/1407540646 This is the current edition of practiced hand software:http://pan.baidu.com/s/1sjjwqpz public String getshaone (string input)//sha-1 encryption { //Gen     SHA1 shaone = sha1. Create (); //Change byte[] shaOneBuffer = Shaone.computehash (Encoding.UTF8.GetBytes (input)); //Guan Shaone.clear (); return bitconverter.tostring (ShaOneBuffer). Replace ("-", ""). ToLower ();///Another simple method} that SHA256 how to use it? Easy, change SHA1 to SHA25.6 on the line, the code is as follows: public string getshax (string input) { // sha256 shax = sha256. Create (); //Change byte[] shaXBuffer = Shax.computehash (Encoding.UTF8.GetBytes (input)); //Guan Shax.clear (); return bitconverter.tostring (Shaxbuffer). Replace ("-", ""). ToLower ();///Another simple method} well, the following highlights my latest encryption results: DNTDBT encryption (dnt big pervert) In fact, it is not my own creation of encryption, is the usual encryption of my own "humanization" plus their own ideas, A little change, and then re-cast the can also be called: SHA series of comprehensive variation "with the SHA512 (currently the most secure encryption)" ~ Encoding format for utf-8 first talk about the idea: Clear text-->sha512-->base64-- >btmd5-->bysha-->sha512-->base64-->bysha (40 bit) "This is called encryption order or some mystery, the specific self-speculation oh ~" Recommend the webmaster with this most complex encryption method to enter the password ~ I put the code in a simple optimization, you can re-optimize (optimize the angle: from saving resources to start) My side is mainly to small white to see can not optimize, otherwise they must not understand code paste: public  STRING DNTDBT (string input) { //Gen sha512 shax = sha512. Create (); //change + off string newinput = getbysha ( GetBTMD5 (GetBase64 (Shax.computehash (Encoding.UTF8.GetBytes (input)))); string strshax = getbase64 (ShaX.ComputeHash ( Encoding.UTF8.GetBytes (newinput)); Shax.clear ();//Release the resources of a series of encryption return getbysha (Strshax);} Does it feel simple? Cough, the following is the real massive code, above is just a method to call multiple methods only ~~  //MD5 small mutation public string getsxmd5 (string input) { //Chong md5 md5 = md5. Create (); //turn byte[] md5buffer = md5. ComputeHash (Encoding.UTF8.GetBytes (input)); stringbuilder sbmd5 = New stRingbuilder (); for (Int i = md5buffer. length - 1; i >= 0; i--) { sbmd5.append (Md5buffer[i]. ToString ("X2")); } //off md5. Clear (); return sbmd5.tostring ();} //sha-1 encryption Public string getshaone (string input) { //Gen sha1 shaone = sha1. Create (); //Change byte[] shaOneBuffer = Shaone.computehash (Encoding.UTF8.GetBytes (input)); //Guan Shaone.clear (); return bitconverter.tostring (ShaOneBuffer). Replace ("-", ""). ToLower ();///Another simple method (can also be done with the above traversal)} //MD5 mutation--a process to become MD5 (guaranteed number of digits) public string GetBTMD5 (string input) { //Gen md5 md5 = md5. Create (); //becomes byte[] md5buffer = md5. ComputeHash (Encoding.UTF8.GetBytes (input)); ////mutation Start Stringbuilder sb = new stringbuilder (); for (int i = md5buffer.length - 1; i >= 0; i--)   {        SB. Append (((int). Parse (Md5buffer[i]. ToString ())) ( - 1). ToString ("X2")); } //off md5. Clear (); //re-reinforcing     RETURN GETSXMD5 (sb.) ToString ());} //base64 encryption (The reason why he was chosen because his address has a variety of special symbols, multiple crack very difficult) public string getbase64 (Byte[] inputbuffer) { reTurn convert.tobase64string (InputBuffer);} //sha-1 Small Variant Public string getbysha (string input) { //Chong sha1 shaone = sha1. Create (); //Change byte[] shaOneBuffer = Shaone.computehash (Encoding.UTF8.GetBytes (input)); string newinput = getbase64 (Shaonebuffer); byte[] shanewbuffer = Shaone.computehash (Encoding.UTF8.GetBytes (Newinput)); //Guan Shaone.clear (); return bitconverter.tostring (ShaNewBuffer). Replace ("-", ""). ToLower ();} Cough, see this shows that you have not been frightened, or that you directly a look thousand line, OK, inverse days have a habit, speak a technical point like hair a big trick, I also made a software for you reference source code as follows: http://pan.baidu.com/s/ 1c0o03qs If you Base64 not understand the encryption, read this article:http://user.qzone.qq.com/1054186320/blog/1409210604 if you MD5 series still do not understand , just read this article: http://user.qzone.qq.com/1054186320/blog/1407540646 If you don't like the icon layout, look at this article: http://user.qzone.qq.com/1054186320/blog/1396659636
