Why do you want N and E? I think exponent is almost always 65537 Some apps display these numbers, e.g. firefox does for X.509 RSA keys. Maybe the app you are using has the value. Not sure the easiest way to get the modulus otherwise but I know you can do it with the bouncycastle java library. > > Here is one RSA 1024 bits public key: > -----BEGIN PGP PUBLIC KEY BLOCK----- > Version: GnuPG v1.4.10 (GNU/Linux) > > mI0ETjgHawEEAMy2xBB1f2tQBd5pIlztN9FrtS3pHEzT73tgOLVLat4h5rhIjMo4 > 9zx7PSucB+v/W/l4w1OuABwXwbiyZmYs6xrXsHWLWS3HQzz1c7Kqytr2yLUn8+Ua > oZfHnHfHXBVen7r3fCF6HmLoUt6i6EMIdKeXgLgw56Imi+vuUP4Tk+T/ABEBAAG0 > PnRvdG8gYmlzICgyw6htZSBlc3NhaSBkZSBjcsOpYXRpb24gZGUgY2zDqSkgPHRv > dG8yQG91aS1vdWkuZnI+iLgEEwECACIFAk44B2sCGwMGCwkIBwMCBhUIAgkKCwQW > AgMBAh4BAheAAAoJEPL2A707YVbW198D/3zFEv9BBwaU1c4ynOzpA7snpe1my79y > FPmPtZ+hA1KIMQjEVhGX2Frg9gI0Ctruoyg6xKnxup/lD90MFGstVg+4NQNrQ69p > oXGV/VlrT0iM0vvN55WIu5Kdqpg2/OHyrABe9mxvRbQRFCXmPSQ5u4V6MJw29W5i > 2jhWZbrxGDASuI0ETjgHawEEALsT4E4TiLKyt7vRADTY2gHOoLISC0Raw/Idxqph > WtMw/onfa75GS8tx6DzTueVULyyWwh+iMMUbX5ZoMvFmpft32NdJBF7FPhFYTfoQ > /qTshjUHMAVsdgjJ4INBUNj8+2TiLdXS1aGxv7chg1OJynGCV3Uw5VFgTVS1GQku > HknJABEBAAGInwQYAQIACQUCTjgHawIbDAAKCRDy9gO9O2FW1nHlA/4p9H+ko3y/ > cuLWUmT5ytq1TYSvFzp7vP2NRlNtgL9RgUSO3T+Qi83RiCrqI6XIGH92cKG661kn > ZFdkD5KUVzyCUV+Aotp10KDlzb9yEPxjULkvgGy7RR5tsP0yDHSdcdZ0qI7Uikla > gfwM5a1NqG2nerqlcvzx4t+Qw/P6OsdcwA== > =lNKN > -----END PGP PUBLIC KEY BLOCK----- > > What are N and e ? > > _______________________________________________ > Gnupg-users mailing list > Gnupg-users@gnupg.org > http://lists.gnupg.org/mailman/listinfo/gnupg-users > _______________________________________________ Gnupg-users mailing list Gnupg-users@gnupg.org http://lists.gnupg.org/mailman/listinfo/gnupg-users
