NAME
    Alt::Crypt::RSA::BigInt - Rewrite of Crypt::RSA

DESCRIPTION

    This is a rework of Crypt::RSA to remove Math::Pari and instead base
    all operations on Math::BigInt.

STATUS

    Version 2.00 is intended to be a plug-in replacement for Crypt::RSA,
    with no user-visible changes.  This means some issues will remain
    unresolved until future versions.

    Math::Pari is completely removed.  This includes the two modules:

       - Crypt::Primes   =>   Math::Prime::Util
       - Crypt::Random   =>   Bytes::Random::Secure

    All operations are now performed using Math::BigInt, and prefer the
    GMP and Pari backends.

PERFORMANCE

    Performance using GMP is 3-10 times faster than the Crypt::RSA 1.99.

    Using Math::BigInt::Pari, it is about half the speed at signing, and
    on par when verifying.

    If neither GMP nor Pari are available, performance is very slow, from
    10x to 200x slower.  However this is an environment where the original
    code could not run.
