It provides functionality for conversation management, multimodal inputs, and streaming mode. Markdown to HTML […]
Starting with the v10.0.0 release (end of September 2024), Chilkat moves to standard semantic versioning. Prior to this release, for various technical reasons, Chilkat was stuck with versions 9.5.0.xx, where only xx changed. For this first leap to semantic versioning, where the major version changes to 10 (from 9), there are no backward incompatible changes. […]
When using non-US-ASCII literal strings (e.g., accented characters like “é”, “ü”, or symbols from other scripts like “你好”) in source code, it’s crucial to handle them carefully due to potential issues with encoding, interpretation, and compatibility. Here’s an explanation of key considerations: 1. Source Code File Encoding Encoding Matters: The source code file must be […]
The maximum number of bytes you can encrypt using RSA depends on the key size and the padding scheme. 1. Key Size The RSA key size determines the maximum size of the plaintext that can be encrypted. The larger the key size (e.g., 1024, 2048, 4096 bits), the larger the block of plaintext that can […]
Optimal Asymmetric Encryption Padding (OAEP) is a padding scheme used in RSA encryption to provide additional security by introducing randomness and structure to the plaintext before encryption. Key Features of OAEP Padding Randomness: Incorporates a randomly generated seed to ensure the same plaintext encrypts to different ciphertexts each time, enhancing security. Two-step Masking: Uses a […]
SQL Server Methods that Return Long Strings Some ActiveX methods return strings that are too long for local string variables. How can these be returned to the calling stored procedure? Answer The Chilkat Global object has a property named KeepStringResult which can be set to 1. (The default value is 0.) When set to 1, […]
RSA Signatures and Endianness RSA signatures are represented as large integers, and the byte order (endianness) determines how the bytes of these integers are stored and transmitted. The two common formats are: Big-endian: The most significant byte (MSB) comes first. This is the traditional format used in network protocols and cryptography. Little-endian: The least significant […]
Next Version: Chilkat v10.1.2 Release Notes Previous Version: Chilkat v10.0.0 Release Notes Prepare for Future Major Version Releases Global.DefaultUtf8: For programming languages where strings are null-terminated byte sequences (e.g., C, C++, Perl, Python 2.*, PHP, Ruby), set the Global.DefaultUtf8 property to true or false at the start of your application, ideally when calling UnlockBundle. The […]
Introduced in version 10.1.0, the Chilkat Secrets class enables managing secrets like passwords and OAuth2 tokens locally (on Windows and MacOS/iOS) and across various cloud platforms. It offers a unified API for seamless secret storage and supports the following standard operations: Create/Update a Secret List Secrets Delete a Secret Get a Secret’s Value Secrets can […]
When including images in an HTML email , there are multiple ways to reference and embed the images. *** Use Chilkat.Email.AddRelatedFile or ChilkatEmail.AddRelatedBd to add an image referenced using Content-ID *** Use Chilkat.Email.AddRelatedFile2 or ChilkatEmail.AddRelatedBd2 to add an image referenced using Content-Location 1. Inline Data URLs Description: The image is embedded directly in the […]
The behavior of the FTP “RNTO” command when the target file already exists depends on the FTP server implementation and configuration. The File Transfer Protocol (FTP) itself, as defined in RFC 959, does not explicitly specify what should happen in this case, leaving it up to the server’s discretion. Typical Behaviors for “RNTO” When the […]
The difference between PKCS7 (CMS) encryption and RSA encryption lies in their purpose, scope, and how they handle encryption. * Output size differences are described further below. PKCS7 (CMS) Encryption Type: A data format and protocol, not an encryption algorithm itself. Purpose: Used for encrypting data and supporting digital signatures in a standard format. Mechanism: […]
