Re: Using DSA generated keys for RSA encryption

["Tolga Acar" <TACAR@xxxxxxxxxx>]

No.
They are different algorithms, and keys are not interchangeable.

Why not: RSA is finding the e-th root of an integer module a composite
integer (integer factorization problem would provide a solution as
well), while DSA is based on the discrete logarithm problem in the
subgroup Zp*.

More plain words, you don't have the primes in RSA [public] key to
construct the DSA subgroup.

Hi List:

I know this might be a rather dumb question:

Can I use DSA keys for RSA encryption? If yes, why? If no, why not?

Raghav
