示例1: decrypt

/**
* Create a decrypted private key with the keyCrypter and AES key supplied. Note that if the aesKey is wrong, this
* has some chance of throwing KeyCrypterException due to the corrupted padding that will result, but it can also
* just yield a garbage key.
*
* @param keyCrypter The keyCrypter that specifies exactly how the decrypted bytes are created.
* @param aesKey The KeyParameter with the AES encryption key (usually constructed with keyCrypter#deriveKey and cached).
* @return unencryptedKey
