revised Rainbow table for DES with all-zero plaintext?
Generalization
1d
revised RSA with modulus n=p²q
Slightly restructure; give standard e.
1d
revised RSA with modulus n=p²q
Fix a formula which was suboptimal (though only when the RNG is hopelessly broken)
2d
revised RSA with modulus n=p²q
More direct link to Fast Variants of RSA

revised Given $g$, $b$, $g^{ab}$, is finding $g^a$ a hard problem?
The method in the other answer needs adapatation if we consider that _g_ is not a generator
