A bigint context may maintain state by being made "permanent". - * It be be later released with a bi_depermanent() and bi_free() call. - * - * It supports the following reduction techniques: - * - Classical - * - Barrett - * - Montgomery - * - * It also implements the following: - * - Karatsuba multiplication - * - Squaring - * - Sliding window exponentiation - * - Chinese Remainder Theorem (implemented in rsa.c). - * - * All the algorithms used are pretty standard, and designed for different - * data bus sizes. Negative numbers are not dealt with at all, so a subtraction - * may need to be tested for negativity. - * - * This library steals some ideas from Jef Poskanzer - * <http://cs.marlboro.edu/term/cs-fall02/algorithms/crypto/RSA/bigint> - * and GMP <http://www.swox.com/gmp>.
