mimekit - MimeKit.Core 5.0.0.2435

MimeKit is an Open Source library for creating and parsing MIME, S/MIME and PGP messages on desktop and mobile platforms. It also supports parsing of Unix mbox files.

  MimeKit.Core provides the core MIME creation and parsing functionality without any dependency on BouncyCastle. For OpenPGP, S/MIME and DKIM/ARC support, add the MimeKit.Cryptography package (or the MimeKit meta-package).

  API documentation can be found on the web at http://www.mimekit.net/docs

  • Removed base, embed, input, link and source tags as "unsafe" tags. These are all void tags in HTML, meaning they do not have inner content. (issue #1247)
  • Fixed InternetAddressListConverter to allow conversion of empty strings into an empty list. (issue #1249)
  • Fixed NullReferenceException in BouncyCastleSecureMimeContext when SubjectKeyIdentifier is requested but not available. (issue #1250)
  • Fixed MimeReader to support MimePart content larger than 2GB. (issue #1252)
  • Fixed Message-Id parser to not decode international domains. (issue #1254)
  • Bumped System.Security.Cryptography.Pkcs dependency to 10.0.0.
  • Bumped System.Text.Encoding.CodePages dependency to 10.0.0.
  • Bumped BouncyCastle.Cryptography dependency to 2.7.0.

Note: As of BouncyCastle 2.7.0, decrypting S/MIME content encrypted with Blowfish, CAST5, RC2/40, RC2/64, or RC2/128 will fail with a CmsException: no fixed size for content-encryption key; constant-time RSA unwrap unavailable.

Use the following code snippet to restore pre-2.7.0 behavior:

Org.BouncyCastle.Utilities.Properties.SetThreadBoolean (Org.BouncyCastle.Utilities.Properties.CmsAllowLenientRsaPkcs1, true);
