is there a possibility to implement bcpowmod() in a
version prior than PHP5?
bcpowmod() ist the only way to calculate a blind signature
as described by David CHAUM 1982 -> digicash
(openssl does not work here).
now I use the "shell_exec" command and an external java applet.
(btw. java has a great implemetation of the BigInteger.class)
