Chilkat v10.1.2 Release Notes
Next Version: Chilkat v10.1.3 Release Notes Previous Version: Chilkat v10.1.0 Release Notes XmlDSigGen: In v10.0.0 Chilkat started automatically using and fixing for SigningCertificateV2 for cases where the xmlns:xades=”http://uri.etsi.org/01903/v1.3.2#” (and also v1.4.1 and v1.4.2), which is technically correct. However many govt validators, specifically Poland, Saudia Arabia, and others, reject XML signatures using SigningCertificateV2. Chilkat backed out […]
How to Suppress the Password Dialog for a Private Key in Apple Keychain
To prevent the password dialog from being shown when you use a private key in the Apple Keychain, you need to adjust the key’s access control settings. Specifically, you can configure the key to allow applications to access it without prompting the user. Here’s how to achieve this: Steps to Prevent Password Dialogs 1. Open […]
Using a .nupkg for Temporary Development Use
To add a reference to a “.nupkg” file (a NuGet package) in a .NET 6.0 project, you can follow these steps: Option 1: Add the .nupkg File to a Local NuGet Source Create a Local NuGet Source: Place your “.nupkg” file in a folder, e.g., “C:\NuGetPackages”. Configure the Local Source in NuGet: Open a terminal […]
Be Careful when Using non-us-ascii String Literals in Source Code
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 […]
RSA Encryption Maximum Number of Bytes
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 […]
More Information about RSA OAEP Padding for Encryption
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
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 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 […]
Chilkat v10.1.0 / v10.1.1 Release Notes
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 […]
