    copied!<p>The jar (bcprov-jdk16-145.jar) has been added to the project, <code>Security.addProvider(new org.bouncycastle.jce.provider.BouncyCastleProvider())</code> has been added to the class, and <code>BouncyCastleProvider.PROVIDER_NAME</code> does return "BC" but AesFileIo.writeFile() still throws <code>java.security.NoSuchProviderException No such provider: BC</code>. Any ideas?</p> <pre><code>import java.io.FileOutputStream; import java.io.InputStreamReader; import java.io.ObjectOutputStream; import javax.crypto.Cipher; import javax.crypto.spec.IvParameterSpec; import javax.crypto.spec.SecretKeySpec; import org.bouncycastle.jce.provider.BouncyCastleProvider; public class AesFileIo { private static final String AES_ALGORITHM = "AES/CTR/NoPadding"; private static final String PROVIDER = BouncyCastleProvider.PROVIDER_NAME; private static final byte[] AES_KEY_128 = { // Hard coded for now 78, -90, 42, 70, -5, 20, -114, 103, -99, -25, 76, 95, -85, 94, 57, 54}; private static final byte[] IV = { // Hard coded for now -85, -67, -5, 88, 28, 49, 49, 85, 114, 83, -40, 119, -65, 91, 76, 108}; private static final SecretKeySpec secretKeySpec = new SecretKeySpec(AES_KEY_128, "AES"); private static final IvParameterSpec ivSpec = new IvParameterSpec(IV); public void AesFileIo() { Security.addProvider(new org.bouncycastle.jce.provider .BouncyCastleProvider()); } public void writeFile(String fileName, String theFile) { try { Cipher cipher = Cipher.getInstance(AES_ALGORITHM, PROVIDER); cipher.init(Cipher.ENCRYPT_MODE, secretKeySpec, ivSpec); byte[] encrypted = cipher.doFinal(theFile.getBytes()); ObjectOutputStream os = new ObjectOutputStream( new FileOutputStream(fileName)); os.write(encrypted); os.flush(); os.close(); } catch (Exception e) { StackTraceElement se = new Exception().getStackTrace()[0]; System.err.println(se.getFileName() + " " + se.getLineNumber() + " " + e); } } } </code></pre>
