Java Security

Hi experts,

What I'm trying to do is loading a DER private key from a file, searching the forum I found this code for loading and decrypting a PrivateKey.

 private static KeyPair obtenerLlavesFormatoDER(byte[] encryptedPKInfo, char[] password){
        KeyPair parDeLlaves = null;
        
        try {
                java.security.Security.addProvider(new BouncyCastleProvider());
                EncryptedPrivateKeyInfo ePKInfo = new EncryptedPrivateKeyInfo(
                                                        encryptedPKInfo);
                Cipher cipher = Cipher.getInstance(ePKInfo.getAlgName(),"BC");
                PBEKeySpec pbeKeySpec = new PBEKeySpec(password);
                SecretKeyFactory skFac = SecretKeyFactory.getInstance(ePKInfo
                                                        .getAlgName(),"BC");
                cipher.init(Cipher.DECRYPT_MODE,
                        skFac.generateSecret(pbeKeySpec), ePKInfo.getAlgParameters());
                PKCS8EncodedKeySpec pkcs8Spec = ePKInfo.getKeySpec(cipher);
                KeyFactory          keyFact = KeyFactory.getInstance("RSA","BC");
                RSAPrivateCrtKey          privKey = (RSAPrivateCrtKey)keyFact.generatePrivate(pkcs8Spec);
                RSAPublicKeySpec rsaPubKeySpec = new RSAPublicKeySpec(privKey.getModulus(), privKey.getPublicExponent());
                RSAPublicKey rsaPubKey = (RSAPublicKey) keyFact.generatePublic(rsaPubKeySpec);
                
                parDeLlaves = new KeyPair(rsaPubKey, privKey);
            } catch (IOException ex) {
                ex.printStackTrace();
            }catch(NoSuchAlgorithmException ex){
                ex.printStackTrace();
            }catch(NoSuchPaddingException ex){
                ex.printStackTrace();
            }catch(NoSuchProviderException ex){
                ex.printStackTrace();
            }catch(InvalidAlgorithmParameterException ex){
                ex.printStackTrace();
            }catch(InvalidKeyException ex){
                ex.printStackTrace();
            }finally{
                return parDeLlaves;
            }
    }

The exeption is launched in the line

Cipher cipher = Cipher.getInstance(ePKInfo.getAlgName(),"BC");

It's a java.security.NoSuchAlgorithmException: No such algorithm: 1.2.840.113549.1.5.13
Can you please give me some advise over what can I do to successfully load the key ?? I'm using BouncyCastle as the JCE provider

Thanks in advance
