v9.5.0.37 Micro Update: Mime.LoadMimeBytes Updated to Handle Mixture of bare-LF and CRLF Line Endingss

It was found that in some cases, OpenSSL may produce MIME with a mixture of both bare-LF line-endings and CRLF line-endings. MIME documents *should* always use CRLF line endings. The mixing of both line-ending types in a single MIME document caused the LoadMimeBytes method to skip past the end of the top-level header (terminated by a double bare-LF) and instead […]

v9.5.0.34 Micro Update: SSL/TLS Perfect Forward Secrecy, Minor HTTP and ASN.1 Fixes

The internal Chilkat SSL/TLS implementation now supports the TLS_DHE_RSA_WITH_AES_256_CBC_SHA and TLS_DHE_RSA_WITH_AES_128_CBC_SHA cipher suites. These allow for perfect forward secrecy. Note: This is implemented on the client-side for all protocols using SSL/TLS.
