Bouncy Castle Default Modes AES 256

I need to know what is the default mode that Bouncy Castle AES 256 uses.

From what i know there are six confidentiality modes (ECB, CBC, OFB, CFB, CTR, and XTS-AES), one authentication mode (CMAC), and two combined modes for confidentiality and authentication (CCM and GCM).

Please tell me which mode Bouncy Castle AES 256 uses by default

There is no such thing as a default mode. You specify the mode by the class you use. – President James K. Polk
Here is the code that decrypts the encrypted data successfully. Cipher cipher = Cipher.getInstance("AES", new BouncyCastleProvider()); cipher.init(Cipher.DECRYPT_MODE, skeySpec); byte[] original = cipher.doFinal(Base64 .decode(encrypted_pin_password.getBytes())); – mujeeb
Hi Guys, this has gotten really urgent. Any help will be much appreciated. – mujeeb

I checked the created Cipher object in a debugger. The Cipher.c member has an org.bouncycastle.jce.provider.symmetric.AES$ECB object. So it looks you are getting ECB mode.
