Seed RSA Generator

[sebastianbuechler]

Is there a way to seed the RSA generator of this package like we can do with pointy castle: https://github.com/bcgit/pc-dart/blob/master/tutorials/rsa.md

If no, what determines the seed here?

Hi @sebastianbuechler currently we don't support using a custom seed to geneate a key, currently we use rand.Reader from go

https://github.com/jerson/rsa-mobile/blob/master/rsa/generate.go#L16

From go docs:
Most applications should use [crypto/rand.Reader] as rand. Note that the
returned key does not depend deterministically on the bytes read from rand,
and may change between calls and/or between versions.

so after read more in deep it seems is something we can adjust to make it safer

it seems we should also allow to set a custom nprime value, which is 2 by default

From go docs:
The use of this function with a number of primes different from
two is not recommended for the above security, compatibility, and performance
reasons. Use GenerateKey instead.
