comment Is there a big RSA Data Set
What do you need that set for? Since you want private keys too, the easiest solution is generating such a set yourself.

@Denis Simply don't use the same key for blind signatures and encryption/normal signatures.

@Denis No the bank doesn't pad. The applicant pads before blinding.
