You need to encrypt your data with an RSA key of 2048 bits (i.e. 256 bytes). In that case the modulus will be 256 bytes and the resulting ciphertext - in this case the wrapped key - will be of that size as well. What you do not need to do is to prefix the decrypted AES key to the ciphertext - that doesn't make sense. homes for sale in mount kiscohip strengtheningWeboracle.security.crypto.coreClass RSA.
