Generate a bitcoin address in PHP WITHOUT GMP or BCMATH

[n4ru]

I'm trying to find a way to generate a private key and public address using only PHP without either GMP or BCMATH. Can it be done at all? The reason for this is I am limited to a hosting provider on the tor network with neither of these.

What are my options?

Private keys are essentially very big numbers, you would need these functions to handle them OR write yourself a custom PHP library to handle big numbers(apparently it's not that hard) and you will be OK.

Doing the math in BC is already painfully slow.  It would be so much worse in pure PHP.
