What do you think a big-integer division by a word-sized divisor *is*? Obviously rolling your own is always an option. Are you just saying that Base58 encoding and decoding is easier than Shamir's Secret Sharing because the divisors are small? ------------------------------------------------------------------------------ Put Bad Developers to Shame Dominate Development with Jenkins Continuous Integration Continuously Automate Build, Test & Deployment Start a new project now.
