PDFBox 1.8.10: Fill and Sign Document, Filling again fails

由 ▼魔方 西西 提交于 2019-12-13 01:27:58
问题 In my previous SO question PDFBox 1.8.10: Fill and Sign PDF produces invalid signatures I explained, how I failed to fill and afterwards sign a PDF-Document, using PDFBox 1.8.10. After this got sorted out with some kind help, I now continue to work on the same topic. Starting with doc_v2.pdf (links to the file are below!), I fill and sign it, resulting in doc_v2_fillsigned.pdf (doing it in one go, saving it incrementally). Again I open the edited document (using again PDFBox) and try to fill

Load a smart card or other private certificate in CryptoServiceProvider for signature

由 邮差的信 提交于 2019-12-13 01:17:31
问题 I'm trying to develop a simple C# signature API to be used by a web intranet procedure. This signature API must allow a subject connected to the web application to use his certificate (on a smart card or on a USB stick) to sign a document (a PDF file). When I try to initialize an RSACryptoServiceProvider as suggested here: http://msdn.microsoft.com/en-us/library/ms229931.aspx: // Create a new CspParameters object that identifies a // Smart Card CryptoGraphic Provider. // The 1st parameter

问题 I've made my front end website in Wordpress and this is fine for me, i want to create the member/staff area in Drupal as it has more functionality with Google docs and Mediawiki. I was wondering if its possible for me to share logins between both sites, so if i register a user on wordpress, they will be able to login on the Drupal site aswell? 回答1: OpenId would be a way to do it , other than that it should be possible to write a function to retrieve the Wordpress users info from the database

Making RSA keys from a password in python

由 别来无恙 提交于 2019-12-12 08:47:28
问题 I want to be able to generate and re-generate the same RSA keys from a password (and salt) alone in python . Currently I was doing it using pycrypto, however, it does not seem to generate the same exact keys from the password alone. The reason seems to be that when pycrypto generates a RSA key it uses some sort of random number internally. Currently my code looks as follows: import DarkCloudCryptoLib as dcCryptoLib #some costume library for crypto from Crypto.PublicKey import RSA password =

Is Maven artifact signing a legitimate use of GnuPG comment in user ID?

由 末鹿安然 提交于 2019-12-12 05:03:04
问题 I'm new to GPG signing and the intricacies are dizzying, as my other, overly-broad question indicates. So let me try to distill my current doubts into a simple question. Let's say that a company Acme wants to sign some artifacts for publishing on Maven Central. From much research from various sources I glean the following best practices: Acme should have one single primary key, e.g. for id@acme.example.com . Acme should generate subkeys for general day-to-day use, such as signing Maven

RSA signing in C#

由 隐身守侯 提交于 2019-12-12 03:25:56
问题 I need to make a software activation mechanism. So i ended up with this scheme: App creates a unique id, based on computer's hardware. Buyer emails this id to me. I sign it with my private key and i send back the signed string. App verifies string (decodes it with contained public key and compares it with hardware id). So far i am done with hardware id and i have created the keys (1024bit) with openssl, that's two files private.pem and public.pem. I worked with some code provided by msdn, but

Replicate OpenSSL command to sign a file in Java

问题 I need to sign a file and so far I've used the openssl comman which is working fine (file is signed and verified). openssl smime -sign -in unsigned.mobileconfig -out signed.mobileconfig -signer myCrtFile.crt -inkey myKeyFile.key -certfile bundleCertificate.crt -outform der -nodetach But now I need to do this on runtime, so I need to sign the file programmatically.
