+ +=head1 DESCRIPTION + +This library performs arithmetic operations on integers of arbitrary +size. It was written for use in public key cryptography, such as RSA +and Diffie-Hellman. + +It uses dynamic memory allocation for storing its data structures. +That means that there is no limit on the size of the numbers +manipulated by these functions, but return values must always be +checked in case a memory allocation error has occurred. + +The basic object in this library is a B. It is used to hold a +single large integer. This type should be considered opaque and fields +should not be modified or accessed directly. + +The creation of B objects is described in L; +L describes most of the arithmetic operations. +Comparison is described in L; L +describes certain assignments, L the generation of +random numbers, L deals with prime +numbers and L with bit operations. The conversion +of Bs to external formats is described in L. + +=head1 SEE ALSO + +L, +L, L, L, L, +L, L, +L, L, L, +L, L, +L, L, L, +L, L, +L, L, +L, +L, +L + +=cut -- cgit v1.2.3
