NAME
asn_mult - multiply two arbitrary size numbers
SYNOPSIS
string asn_mult(string a, string b, string m)
DESCRIPTION
Compute a multiplied by b modulo m. The modulus must be larger than
zero.
Arbitrary size numbers are encoded as strings, most significant byte
first. The most significant bit in the first byte, when set, indicates
that the number is negative and encoded in two's complement.
ERRORS
An error will result if the modulus is less than or equal to zero.
