I try to read encrypted data, but always get java.io.IOException: last
block incomplete in decryption
Setup works like this:
final KeySpec keySpec = new PBEKeySpec(passPhrase.toCharArray(),
SALT, ITERATIONS);
key =
SecretKeyFactory.getInstance("PBEWithMD5AndDES").generateSecret(keySpec);
//
ecipher = Cipher.getInstance(key.getAlgorithm());
paramSpec = new PBEParameterSpec(SALT, ITERATIONS);
// Create the ciphers
ecipher.init(Cipher.ENCRYPT_MODE, key, paramSpec);
Reading the Input:
public InputStream getDecryptStream(final InputStream out) throws
IOException
{
try
{
ecipher.init(Cipher.DECRYPT_MODE, key, paramSpec);
}
catch (InvalidKeyException e)
{
// TODO Auto-generated catch block
e.printStackTrace();
}
catch (InvalidAlgorithmParameterException e)
{
// TODO Auto-generated catch block
e.printStackTrace();
}
return new CipherInputStream(out, ecipher);
}
Anyone can give me an Advice how to get it to work ?
Best regards,
Jens
