I believe conversion exactly to BigInteger[] would be optimal in my case. Anyone had done or found this written in Java and willing to share?

So imagine I have arbitrary size byte[] = {0xff,0x3e,0x12,0x45,0x1d,0x11,0x2a,0x80,0x81,0x45,0x1d,0x11,0x2a,0x80,0x81} How do I convert it to array of BigInteger's and then be able to recover it back the original byte array safely?

ty in advance.
