posted July 17, 2015 8:23 AM Hi, I'm using the latest dll version. We receive emails containing signature.asc file. It comes from https://www.gnupg.org/ progject. For these emails: - IsSecure returns true - SecureEncoding type is SignedDetached If I use SecureDecode() it throws an exception: "System.FormatException: Second part (Parts[1]) is not the required digital signature. at Dart.Mail.MailMessage.SecureDecode(X509Certificate2Collection decryptingCertificates, Boolean importSigningCertificate) at Dart.Mail.MailMessage.SecureDecode() After this exception IsSecure still returns true. Although the email is secured it is not encrypted and can be processed. I don't get when I have to use SecureDecode() and when it is not necessary. Do I have to call it only when SecureEncoding type is Encrypted? Could you give me a hint? FYI: the email structure: MIME-Version: 1.0 --NetatworkMailGateway_4cce080c-785f-49f1-a1d1-2bcfbeece277 Content-Type: multipart/mixed; boundary="_004_b8549515aad8411c8796baaa718b6b85rz1exc02internkasse_" --_004_b8549515aad8411c8796baaa718b6b85rz1exc02internkasse_ Content-Type: multipart/alternative; boundary="_000_b8549515aad8411c8796baaa718b6b85rz1exc02internkasse_" --_000_b8549515aad8411c8796baaa718b6b85rz1exc02internkasse_ Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: quoted-printable Clear text --_000_b8549515aad8411c8796baaa718b6b85rz1exc02internkasse_ Content-Type: text/html; charset="iso-8859-1" Content-Transfer-Encoding: quoted-printable <html> ... </html> --_000_b8549515aad8411c8796baaa718b6b85rz1exc02internkasse_-- --_004_b8549515aad8411c8796baaa718b6b85rz1exc02internkasse_ Content-Type: application/pdf; name="SD9103315071414580.pdf" Content-Transfer-Encoding: base64 Content-Disposition: attachment; filename="SD9103315071414580.pdf" ... --_004_b8549515aad8411c8796baaa718b6b85rz1exc02internkasse_-- --NetatworkMailGateway_4cce080c-785f-49f1-a1d1-2bcfbeece277 Content-Type: application/pgp-signature; name="signature.asc" Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: enQsig ... -----END PGP SIGNATURE----- --NetatworkMailGateway_4cce080c-785f-49f1-a1d1-2bcfbeece277-- |

posted July 24, 2015 2:52 PM Thank you for your recent post. The component does not currently support verifying emails signed using the OpenPGP/PGP specification. Support is included for S/Mime, which is a separate specification. We've added a feature request to consider for a future release.(Feature Request #697) Please email jamie.powell@dart.com if this feature is required immediately and I will be happy to provide information on our priority support options. Best regards, Jamie |
