this question has answer here:

• asp.net connectionstring in secure way 7 answers

i'd begin new project , 1 of first problems i've figured out security of mysql connection data.

i want know if it's possible configure software choose database server; reason it's necessary store connection informations (user, password, databasename) in kind of file (xml, bin, ...) thats not safe , viewed due lack of encryption.

is there easy way protect these sensitive informations or have write own encryption mechanism ?

in case have write own one, there guideline right?

no, don't need write own encryption it, .net have encryption.

simply use rijndael (aes) - encryption.

import namespace: using system.security.cryptography;

then use class: rijndael class

and take @ thread: how generate rijndael key , iv using passphrase? use encryption properly/safely.

example:

 private static byte[] encryptstring(byte[] cleartext, byte[] key, byte[] iv)     {         memorystream ms = new memorystream();         rijndael alg = rijndael.create();         alg.key = key; //look @ linked stackoverflow-thread         alg.iv = iv; // on how create key , iv         cryptostream cs = new cryptostream(ms, alg.createencryptor(), cryptostreammode.write);         cs.write(cleartext, 0, cleartext.length);         cs.close();         byte[] encrypteddata = ms.toarray();         return encrypteddata;     }
