Unsigned signature fields in a PDF are placeholders for digital signatures that can be added to a PDF document at a later time. These fields are often created by the author or originator of the document, and they indicate where and how a digital signature should be placed.

The “signingTime” authenticated attribute in PKCS #7 (now part of Cryptographic Message Syntax or CMS) signatures is an optional attribute that indicates the date and time when the digital signature was created. It is commonly included in signed-data objects to provide a timestamp that can help verify when a signature was applied. Detailed Explanation: Attribute OID: The “signingTime” attribute is […]
Question: I got the following error when trying to instantiate an ActiveX object in my VBScript (.vbs) Code “800A01AD”Message “ActiveX component can’t create object: ‘Chilkat.Cert’” Answer: It means the ActiveX is not registered. Yes, you probably registered the ActiveX, but you need to understand if your VBScript is running as a 32-bit process, or a 64-bit process. You then need […]
To run a .vbs VBScript explicitly as either a 32-bit or 64-bit process on a 64-bit Windows system, you need to specify which version of the Windows Script Host (wscript or cscript) to use. By default, the script runs using the version of the Windows Script Host that matches the bitness of the environment in which it is invoked (32-bit […]

These files are commonly encountered in contexts like secure email and digitally signed documents. 1. What is a .p7m File? A .p7m file is a digitally signed or encrypted file that uses the PKCS #7 (Public Key Cryptography […]
Chilkat v10.0.1 is a patch for certain builds of Chilkat.

This post explains how to create an Azure App Registration that will be used by applications that will authenticate using a digital certificate. To use a certificate for authentication with Microsoft Graph (or any other service that supports OAuth2 client credentials flow with certificates), you typically follow the App-Only Authentication method. This method is used when you’re performing tasks as […]
The ability to refresh an OAuth2 access token using a refresh token depends on the following factors: The Expiration of the Refresh Token: Refresh tokens typically have longer lifetimes than access tokens, and in some cases, they may not expire at all (until revoked). However, some authorization servers issue refresh tokens with expiration times. The expiration time can vary depending […]
