Translate Java to Python -- signing strings with PEM certificate files


Translate Java to Python -- signing strings with PEM certificate files

Any of those help I looked into doing this with pyCrypto and keyczar but the problem is neither have the ability to parse X509 certificates (keyczar has keyczar.util.ParseX509() but it is limited and doesn't work for the AWS cert or I'm guessing any real world cert).
I believe M2Crypto works though. See the following code snippet, which needs a real signature and plaintext filled in to really test.

wish help you to fix your issue First, certificates are not "SSL certificates". They are x.509 certificates, some of which can be used for SSL/TLS authentication. If you have such certificate, you can't use it for other purposes including PDF signing.
Next, .cer file is a public part of the certificate, it doesn't include a private key. You need a certificate and a private key to sign anything.

Corporate Java Webstart Distribution: use site-wide accepted certificate to sign a code-signing certificate

it helps some times If the corporation has its own CA root cert, which yes had to be pushed to every client/relier by some means such as GPO or installing all systems (or maybe their JREs?) from a customized image, then your approach is almost correct:
generate keypair and CSR send CSR to corporate CA, they send you back cert combine cert with keypair in keystore and use keystore

wish of those help I finally solved it - here is the story:
When I bought the certificate, I had to collect it by navigating to a website address that I received by email. There, the certificate was automatically installed into the truststore of my browser (Firefox).
Difference between code signing certificate and document signing certificate

Difference between code signing certificate and document signing certificate

it helps some times Most likely those code signing certificates have an extKeyUsage (2 5 29 37) extension with value codeSigning (1 3 6 1 5 5 7 3 3) and probably also commercialCodeSigning (1 3 6 1 4 1 311 2 1 22) but no values allowing other uses. (At least that is the case for a code signing certificate I have at hands here.)
RFC 5280 specifies for the Extended Key Usage extension that if the extension is present, then the certificate MUST only be used for one of the purposes indicated.
