MailBee.NET Security classes enable .NET applications to sign, verify, encrypt, decrypt e-mails, work with DomainKeys/DKIM, S/MIME, SSL/TLS, public and private certificates (including PFX), use MailBee.NET SMTP/POP3/IMAP components to connect to secure mail servers (like Gmail and MS Exchange) in both dedicated and StartTLS modes, use Windows impersonation. FIPS 140-2 compatible.
These classes are intended to be used with other MailBee.NET components. MailBee.NET Security acts as a set of helper classes which adds more features to the core MailBee.NET functionality.
DomainKeys/DKIM and SSL/TLS support is available at no additional cost, only the corresponding MailBee.NET SMTP/POP3/IMAP license is required. Using certificates and S/MIME does require separate MailBee.NET Security license.
The key features: - SSL/TLS connections with mail servers, up to TLS 1.2; - connections to dedicated SSL ports and to regular ports (STARTTLS); - client and server certificates; - validation of server certificate; - certificate and certificate store management (reading from or saving into a file, registry, memory, etc); - enumerating and finding certificates in certificate stores; - private/PFX certificates; - digital signatures; - S/MIME: sign, verify, encrypt, decrypt messages; - security algorithms, CryptoServiceProviders, etc; - DomainKeys anti-spam technology (creating and verifying DomainKeys and DKIM signatures); - impersonation; - integration with Smtp, Pop3, Imap and MailMessage components of MailBee.NET Objects suite; - error handling features.
The assembly DLL is completely written in C# (no external COM dependencies). Supports .NET 2.0/3.0/3.5/4.0/4.5/4.6/4.7 (including Client Profile) and .NET Core 1.0/1.1/2.0 (partially), both 32-bit and 64-bit. Also supports Xamarin (Mono on Linux, iOS, Android) and UWP (partially).
Samples are available for C# and VB.NET, WinForms and ASP.NET.
