    copied!<p>In my application I am using encryption and decryption.</p> <p>Before entering the string in to local database, I am encrypting that and after fetching the data from database I am decrypting it and using in my application. It is working fine. I have used encryption/decryption from <a href="http://blog.objectgraph.com/index.php/2010/04/20/encrypting-decrypting-base64-encode-decode-in-iphone-objective-c/" rel="nofollow">link below</a></p> <p><strong>At the time of Encrypting:</strong></p> <pre><code> NSString *myKey=@"any string more than 8 char"; NSData *data ; NSData *encryptedData; NSString *encryptPassword,*encryptPasscode; // 1) Encrypt data = [password dataUsingEncoding: NSASCIIStringEncoding]; encryptedData = [data AESEncryptWithPassphrase:myKey]; // 2) Encode Base 64 [Base64 initialize]; encryptPassword = [Base64 encode:encryptedData]; </code></pre> <p><strong>At the time of Decrypting :</strong></p> <pre><code> NSData *decryptedData; NSData *b64DecData; field1 = (char *) sqlite3_column_text(selectPasscodeStatement, 0); NSString *fieldStr1 = [[NSString alloc] initWithUTF8String: field1]; // 3) Decode Base 64 b64DecData = [Base64 decode:fieldStr1]; // 4) Decrypt decryptedData = [b64DecData AESDecryptWithPassphrase:myKey]; retrivedPasscode = [[NSString alloc] initWithData:decryptedData encoding:NSASCIIStringEncoding]; </code></pre> <p>But I have made staticLibrary of that same project. I am using that staticLibrary in another project. When I run that project, at the time of encrypting it gave me error below</p> <blockquote> <p><strong>-[NSConcreteMutableData AESEncryptWithPassphrase:]: unrecognized selector sent to instance 0x6a3fe40</strong></p> </blockquote>
