k = 3

p = 5300683
xx = 163350155649156113641909525
assert xx < p**k
yy = pow(xx, e, p**k)
f = lambda x: (pow(x, e, p**k) - yy) % p**k
df = lambda x: (e*pow(x, e-1, p**k)) % p**k
a = [x for x in range(p) if (pow(x, e, p) - yy) % p == 0]
assert any((x - xx) % p**k == 0 for x in hensel_lifting(f, df, p, k, a))

if I set the exponent to 3, this doesn't fail

First of all, thanks for this repo!

I am trying to make your work available on NixOS.
The expression to build the package is done, and the PR is pending at NixOS/nixpkgs#73069 .

However, a license is usually required as meta-information related to the package, and it seems to be missing from here.
Under which license is this work available?

Thanks!

I really like the aim of this project. I was thinking of building one by myself and then I found this.

Anyway, why the main folder is called p4team? Is this some kind of "private"/"exclusive" software?
I think that this library should be "team"-less as I'm willing to help writing some code.

Another question, classic cipher code (like Kasisky over Vigenere, Playfair Enc/Dec) is in the scope of this library or it's Modern Crypto only?

Thanks
