The Libgcrypt manual has a description of its architecture [1].  GnuPG
uses Libgcrypt and thus that library is responsible for creating RSA
keys.  Libgcrypt is actually code stripped from an older version of
GnuPG, but the basic operation is even the same in the old versions
(i.e. GnuPG <= 1.4).




Die Gedanken sind frei.  Ausnahmen regelt ein Bundesgesetz.
