Chilkat 4-Jan-2022

Started publishing packages for Electron versions 12 to 16, starting with MacOSX and 64-bit Linux. […]

Chilkat 29-Dec-2021 – IMAP Server Response: BAD Command received in Invalid state

What’s going on in Chilkat support today… 1. Extremely long HTTP request headers can be a problem.  (Headers that are more than 1000 characters in length)  Some HTTP servers reject them unless the MIME header is folded.  Some servers are OK with long headers.  If folded to multiple lines, MIME headers need to fold opportunistically at whitespace. If there is […]

Chilkat 24-Dec-2021 — CMS Sign Hash

What’s going on in Chilkat support today… 1. A customer needs a way to create a CMS detached signature from a pre-computed hash.  Oddly, Chilkat did not yet have a function for doing it.  The CMS signature functions in Crypt2 accept data and do the hashing internally.  Chilkat is adding a Crypt2.SignHashENC method, as shown here in this example:  […]

Chilkat 20-Dec-2021 — Does Chilkat support .NET Standard?

What’s going on with Chilkat support today… 1. Does Chilkat support .NET Standard?  We get this question from time to time.  It’s usually because there’s great confusion about the meaning of .NET Standard vs. .NET Core vs. .NET Framework ( and now .NET 5 and .NET 6).   It’s best to first get a solid, basic understanding of the matter.  I […]

Chilkat 16-Dec-2021 — idToken HTTP Header

What’s going on w/ Chilkat support today… 1. Long HTTP request headers present a difficulty because some web servers choke on header fields that are too long and require folding, whereas others choke on folded headers.  Given that HTTP requests are MIME, and the request/response headers are MIME headers, header folding follows the MIME specification.  Folding SHOULD occur at whitespace.  […]

Chilkat 14-Dec-2021 — PDF Signature Notes

What’s going on with Chilkat support today… 1. The Http.PostJson, PostJson2, and PostJson3 methods neglect to send a Content-Type header if a completely empty body is sent.  Starting in the next version (v9.5.0.90) Chilkat will always send the Content-Type header for these methods even if the JSON body is completely empty (i.e. a zero-length string where the Content-Length of the […]
