Import PKCS7 (Chained Certificate) using KeyTool command to JKS

由 青春壹個敷衍的年華 提交于 2019-12-05 03:27:49
I have a CA issued CERT in PKCS#7 format. It has certificates (chained) within it. Keytool does not recognize the PKCS7 format. I have tried OpenSSL tool to convert PKCS7 format certificate to PEM format and it fails. I receive an error message "Unable to load PKCS7 object". How do I import the PKCS7 cert chain to my JKS? As you can read in the keytool reference for -importcert command: Reads the certificate or certificate chain (where the latter is supplied in a PKCS#7 formatted reply) from the file cert_file, and stores it in the keystore entry identified by alias. If no file is given, the

问题 I am using pkcs7 encrypt decrypt in current project. I want to change from PHP to Node.js. Is there pkcs7 encrypt/decrypt in Node.js ? In PHP, <?php $data = <<<EOD Hello world EOD; // load key $key = file_get_contents("mypublickey.crt"); // save message to file $fp = fopen("msg.txt", "w"); fwrite($fp, $data); fclose($fp); // encrypt it if (openssl_pkcs7_encrypt("msg.txt", "enc.txt", $key,array())) { // message encrypted - send it! } ?> to decrypt <?php // The certification stuff $public =

I have been working with itextpdf-5.5.5, and the Integrity check return false. PdfPKCS7 pkcs7 = fields.verifySignature(name); pkcs7.verify();<------ HERE return false But Adobe Acrobat Reader say: Signed and all signatures are valid. :( This is the document: Test.pdf . Could someone explain what is happening?. Thanks in advance The CMS signature container embedded in your PDF has some questionable properties. In particular it has an encapsulated content, even though it merely is a byte array of length 0. This makes iText include this value in a test which then fails. I would propose creating

Automate export x509 certificate w/chain from Server 2008 R2 to a p7b file WITHOUT external tools?

由 ▼魔方 西西 提交于 2019-12-04 12:17:29
I manage the Domain Controllers centrally, but the site admins manage their own digital senders locally. I can easily export an X509 certificate (private key not needed) with the whole chain from a Windows Server 2008 R2 Domain Controller to a p7b file through the wizard: ~~~~~~~~~~~~~~~~~ ...5. The Certificate Export Wizard opens. Click Next. In the Export File Format dialog box, do the following: a. Select Cryptographic Message Syntax Standard – PKCS #7 Certificates (.P7B). b. Check Include all certificates in the certification path if possible. c. Click Next. In the File to Export dialog

问题 I am trying to sign and verify sign using PKCS#7. I am following book beginning cryptography with java . I have written sample code to sign and verify. When i am trying to attach a signature and write it to a file and then trying to verify i am getting exception (Exception is given below ) I want to know how do we write this signed data to a file ? Do i need to share keystore also to second person who will verify the sign? org.bouncycastle.cms.CMSException: message-digest attribute value does

PKCS#7 data payload unpacking with NodeJS?

I'm working on an MDM NodeJS server for iOS. On the Apple docs, the following ruby code is given : p7sign = OpenSSL::PKCS7::PKCS7.new(req.body) store = OpenSSL::X509::Store.new p7sign.verify(nil, store, nil, OpenSSL::PKCS7::NOVERIFY) signers = p7sign.signers What would be the equivalent in NodeJS? The idea is to access p7sign.data that contains an xml plist. Is this possible using either crypto or an external node lib ( ursa , etc)? A good option would be to use child_process to invoke openssl directly. I do that to validate iOS .mobileprovision files. $ openssl smime -verify -in FILE -inform

问题 I would like to parse android apk's CERT.RSA in Python. I know it can be parsed with pyOpenSSL import OpenSSL cert = OpenSSL.crypto.load_certificate(OpenSSL.crypto.FILETYPE_ASN1, open('CERT.RSA', 'rb').read()) cert = OpenSSL.crypto.load_pkcs7_data(type, buffer) cert is of type 'OpenSSL.crypto.PKCS7'. BUT right now PKCS7 object is not complete, I cannot get attributes I need, is there any alternative way to parse that file? 回答1: Comments : I don't know if there's a way to convert it to another

问题 I would like to use PKCS7 encryption to encode a value together with Java and Java Servlet. Is there any available library and references to do the encryption? Any sample or tutorial that I could follow? Thank you. 回答1: For general cryptografy I use bouncycastle library.
