That NSDecimalNumber is essentially the 128-bit quadruple-percision float number, in an non-IEEE-754 fashion.
You can still use OpenSSL, either ignore the deprecation or compile and carry your own copy. Apple deprecated it because OpenSSL API isn’t stable enough. Alternatively, you can use other bignum implementations like GNU MP + GNU MPFR, or if you dare to spend the time, you can translate Java BigInteger and BigDecimal to Objective-C as subclasses of NSNumber. (I would like to see the latter being done by someone and open sourced it.)
