Alt::Crypt::RSA::BigInt - RSA public-key cryptosystem, using Math::BigInt
This is a modification of the Crypt::RSA module to remove all use and dependencies on Pari and Math::Pari.
This first version 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 => Math::Prime::Util
All operations are now performed using Math::BigInt, and prefer the GMP and Pari backends.
Performance using GMP is 3-10 times faster than 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.
Vipul Ved Prakash wrote the original Crypt::RSA.
Dana Jacobsen did the changes to Math::BigInt.
