Chilkat v11.5.0 Release Notes
✨ New Features HttpCurl A new Chilkat class has been added: HttpCurl The Chilkat.HttpCurl class executes curl commands and can automatically resolve dependent values needed by a request. Variables such as {{access_token}}, {{site_id}}, or {{drive_id}} may appear in URLs, headers, query parameters, or request bodies. If a variable is not yet known, HttpCurl builds […]
Chilkat v11.4.0 Release Notes
✨ New Features Js A new Chilkat class has been added: Js is a minimal, standards-compliant JavaScript engine designed to embed JavaScript inside applications with very small footprint and fast startup. It executes JavaScript code inside an application without requiring a browser or large runtime. See About the Chilkat.Js JavaScript Engine Ai Provider — […]
C++ String Compression: PPMD, Deflate, BZip2, LZW
This C++ example demonstrates string compression using four different compression algorithms: PPMD, Deflate, BZip2, and LZW. void TestCompression(const char *algorithm) { CkCompression comp; comp.put_Algorithm(algorithm); printf (“algorithm: %s\n”,algorithm); CkByteData compressedData; comp.CompressString(“abc abc abc abc abc abc abc abc abc abc abc 123 123 abc 123”,compressedData); // Get the compressed data: const unsigned char *pCompressedData = compressedData.getBytes(); […]
Inflate from Zip to memory in C++
This example demonstrates how to inflate in-memory from a Zip in C++: CkZip zip; … // Assume we have a CkZip object and a .zip has been loaded. // It may have been loaded from a file by calling OpenZip, or from an // in-memory image of a .zip by calling OpenFromMemory. // (or any […]
Non-English String Literals in C++ Source Code
When a C++ compiler compiles a C++ source file, it must process the bytes according to a character encoding and that is typically ANSI. ANSI is not a character encoding, it is simply a keyword that says “Use the default multi-byte character encoding for this computer based on its current locale.” Therefore, if your program […]
Utf8 C++ property allows for utf-8 or ANSI “const char *”
All Chilkat C++ classes have a Utf8 property. For example: class CkEmail : public CkObject { public: CkEmail(); virtual ~CkEmail(); … bool get_Utf8(void) const; void put_Utf8(bool b); … const char *addFileAttachment(const char *fileName); … }; The Utf8 property controls how the bytes pointed by “const char *” arguments are interpreted. By default, “const char *” […]
C# Encrypting/Decrypting with Stream
This C# example demonstrates how to use Chilkat.Crypt2 to encrypt and decrypting using the .NET FileStream class: Chilkat.Crypt2 crypt = new Chilkat.Crypt2(); bool success = crypt.UnlockComponent("Anything for 30-day trial"); if (!success) { MessageBox.Show(crypt.LastErrorText); return; } crypt.CryptAlgorithm = "aes"; crypt.CipherMode = "cbc"; crypt.KeyLength = 128; crypt.SetEncodedIV("0000000000000000", "hex"); crypt.SetEncodedKey("abcdefghijklmnop", "ascii"); // Open input and output files as […]
Choosing Correct C++ Library for Linking
When linking with a Chilkat C++ library, you must choose the .lib that matches your project’s “code generation” property setting. For example, in VC++ 8.0, these are the Chilkat .lib’s: ChilkatDbg.lib ChilkatDbgDll.lib ChilkatRel.lib ChilkatRelDll.lib If “Dll” is in the library name, it means that you are *not* statically linking with the C runtime libs. Just […]
C# 3DES (Triple-DES) Test Vector
This post provides C# sample code for matching a test vector (known answer test). 3DES Settings: ECB Mode 192-bit key (i.e. 3 8-bit keys) ASCII Key Bytes: 1234567890123456ABCDEFGH ASCII Text to Encrypt: The quick brown fox jumped over the lazy dog Pads with zero bytes Hexadecimalized Encrypted Result: 13d4d3549493d2870f93c3e0812a06de467e1f9c0bfb16c0 70ede5cabbd3ca62f217a7ae8d47f2c7bf62eb309323b58b C# Code: string keyAscii = […]
