问题 This is what I have right now to generate a digital certificate. And now I'm able to generate a digital certificate with password protected for private key. public static void main(String[] args) throws Exception { Security.addProvider(new BouncyCastleProvider()); testKeyStore(); } public static void testKeyStore() throws Exception { try { String storeName = "d://suresh_test.cer"; java.security.KeyPairGenerator keyPairGenerator = KeyPairGenerator .getInstance("RSA"); keyPairGenerator

what is the difference between X509_STORE and X509_STORE_CTX .?

问题 can any one tell me how the Certificate trust chain is formed with these structures and what these two structure represent? 回答1: Taken from the source code in x509vfy.h: The X509_STORE holds the tables etc for verification stuff. A X509_STORE_CTX is used while validating a single certificate. The X509_STORE has X509_LOOKUPs for looking up certs. The X509_STORE then calls a function to actually verify the certificate chain. The X509_STORE represents more or less your global certificate

How do I create my own Extended validation certificate to display a green bar?

I created one root, one intermediate certificate. Then I signed my Extended Certificate, but it did not. I added root and intermediate certificates to the browser and to the computer' keystore. I see the word "Secure" but I want to see my name in the green bar. What is the policy for generating one extended certificate with OpenSSL? certificatePolicies=ia5org,1.2.3.4,1.5.6.7.8,@polsect [polsect] policyIdentifier = 1.3.5.8 CPS.1="https://jitc.rahmican.com.tr"; userNotice.1=@notice [notice] explicitText="Explicit Text Here" organization="rahmican ltd sti" noticeNumbers=1,2,3,4 I used the

Validating a signature without intermediate certificate

可紊 提交于 2019-12-05 04:07:35
Is it possible to validate a signature only having an ancestor or root certificate in the hierarchy? Disclaimer: I'm a newbie to the certificates handling so please forgive the naive terminology. Consider the following situation. We have two parties (let's call them IdP for Identity Provider and SP for service provider) and some central certificate authority CA which is definitely trusted by both IdP and SP. CA has it's own certificate CertCA known to both IdP and SP (imported into IdP's and SP's keystore under some alias) Out CA issues one certificate for IdP ( CertIdP ) and one for SP (

java keystore and password settings

问题 I have the following question on java keystores and keytool. I assume that a keystore may have more than 1 certificates. As I have tried, via keytool I can create a keystore, and to access this keystore I have to set a password. Also to access each certificate entry I have to set a password. Is it mandatory to have the same password for the keystore and the entries? If not (and I think that it is reasonable to assume so) why is the following code: char[] pwd = new char[]{'s','e','c','r','e',

Data signatures using Perl

I have been this project which involves sending of signed data. I have been provided with a .pem file and a server certificate which I am supposed to import to another server from which I should sign the data using these files and then send over the signed data to another server for verification adn processing. My Questions are: How do I import these two files into my server? How do I use perl to use the files to sign the data? To note, I am to import into a linux (Suse). This is what I have done so far I have added the .pem file to /etc/ssl I am using the below code to read from the .pem file

Is there a way to check if the SSL digital certificate is valid without installing on the web server?

▼魔方 西西 提交于 2019-12-04 04:10:52
Are there any tools or mechanism(s) which can help validate a CA issued SSL certificate before installing it on the target web server? Yes, you can use openssl to create a test server for your certificate with the s_server command. This creates a minimal SSL/TLS server that responds to HTTP requests on port 8080: openssl s_server -accept 8080 -www -cert yourcert.pem -key yourcert.key -CAfile chain.pem yourcert.pem is the X.509 certificate, yourcert.key is your private key and chain.pem contains the chain of trust between your certificate and a root certificate. Your CA should have given you

Is it possible to sign a java applet for free?

戏子无情 提交于 2019-12-03 07:17:09
问题 I made a weird applet which allows you to paint with your voice. Obviously it requires access to the microphone, but Java applets are not allowed access unless they are signed. As far as I can tell its difficult and involves cryptography, and, though its not clear, I think that I'm expected to pay MONEY to Verisign as well. This all seems like a lot of paranoid innovation stifling bullsh** to me and I figure I'm not the first person to think so. Is there just some way to bypass this "for
