The encrypted blob is exactly 256 (keysize/8).
The plain text within that blob is at same length.
The PKCS#5 padding that we should use (or should have used) takes at lease one byte from suffix, hence the <256, but this applies to the plain text.
>From the exception we see that the java crypto provider complains we provide a block >256 and key size of 2048, so there is something wrong with the buffer we pass as it must be =256 bytes.
