Using a self-signed certificate to create a secure client-server connection in android
There is different ways to solve your problem but here is the one I use: All the steps are in this link http://blog.antoine.li/2010/10/22/android-trusting-ssl-certificates/ but some parts can be confused so I will explain all the process: 1.-Store your mycrtfile.crt in a know path I will say c:BKS/mycrtfile.crt. 2.-To create your BKS or key store you will need the file bcprov-jdk15on-146.jar, this class will do all the work for us, there are different versions but this one works for me http://www.bouncycastle.org/download/bcprov-jdk15on-146.jar also store this file into C:BKS/ 3.-Now you will use the Keytool (keytool comes with the Java SDK. You should find it in the directory that contains javac) to generate our keystore and to make sure that is working go to your cmd and type "Keyt

How to use self signed certificate at iOS app
looking at the first tutorial you linked to you should be able to use that or some more advanced form of that and once you have tested and have it working then all you have to do for a client to create and add their own certificate would be to override/replace the localhost.cer file in the apps folder where the file localhost.cer "or whatever name scheme you use" is located. there are many ways to do this but one could be telling the app a link where the certificate is online for download and once downloaded, then replace. Any questions I'll try and help further but hopes this helps you in the right direction.

Using JavaMail with a Self Signed Certificate
Get rid of the socket factory stuff: Setting various socketFactory properties. Long, long ago JavaMail didn't have built in support for SSL connections, so it was necessary to set these properties to use SSL. This hasn't been the case for years; remove these properties and simplify your code. The easiest way to enable SSL support in current versions of JavaMail is to set the property "mail.smtp.ssl.enable" to "true". (Replace "smtp" with "imap" or "pop3" as appropriate.) See these Gmail examples. The Gmail certificate needs to be in your trust store, not your key store.

AJAX and self-signed certificate
I have had this same problem several times. The best I could come up with was something like this: check for a cookie, if they have it, do nothing, if they do not have it, issue a re-direct to the site that generates the cert warning, user accepts the self-signed cert, then the user just needs to go back to your site. If you had any control over the api side, you could probably make it so that you have a bounce back url or something that ends up getting the user back to your site. There really is no elegant way to handle this short of just getting a real SSL cert. On another site, we ended up having to put a link to the service on our page for this very reason, fortunately it was temporary as we had control over the server side too, and planned on replacing the self-signed cert with a real

How to verify that app was signed by my certificate?
Use your code for collecting the fingerprint on the device in "test" mode -- meaning you have temporary code to emit that fingerprint to the log (or elsewhere). Be sure to test this using your production signing key, not the debug key! Once you know from the device's perspective, you can remove the temporary code and elsewhere you can compare to what you've previously determined to be the key. Be aware though that you're probably doing this to prevent someone from modifying your app and re-signing it with another key, but someone with the ability to do that also has the ability to modify your key checking. This is a problem that can be addressed with additional obfuscation but you'll need to come up with your own solution to minimize the chance of an attacker knowing what to look for.

TLS: How to verify a certificate self-signed with an RSA key
Certificates bind a public key and additional information (such as a identifier and other attributes) together. What makes this association between the public key and the additional information a certificate is the fact it is signed. The reason X.509 certificates are signed and issued by a CA is because the CA asserts the binding between the public key and the rest of the content of the certificate (in particular its subject). The purpose of this is to let a party that knows the CA but doesn't necessarily know the entity to which the certificate was issued verify that the content of the certificate is true, in particular that the public key belongs to the certificate's subject. Since your authentication scheme relies on pre-established knowledge of who or what owns the public keys anyway

How i can create a self-signed certificate using phpseclib
You need a private key, plain and simple. Otherwise, what are you going to sign it with? The signature field of an X.509 cert is mandatory. I mean, if all you want is a public key, you don't need to bother with the X.509 overhead. You can just pony up a public key that looks like this: -----BEGIN PUBLIC KEY----- MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQCqGKukO1De7zhZj6+H0qtjTkVxwTCpvKe4eCZ0 FPqri0cb2JZfXJ/DgYSF6vUpwmJG8wVQZKjeGcjDOL5UlsuusFncCzWBQ7RKNUSesmQRMSGkVb1/ 3j+skZ6UtW+5u09lHNsj6tQ51s1SPrCBkedbNf0Tp0GbMJDyR4e9T04ZZwIDAQAB -----END PUBLIC KEY----- But X.509 is more than just a public key - it's a signed public key. Technically, a CSR is, too, but CSR's are always self-signed whereas X.509 certs can be signed by anyone.

Apache couchDB CA signed certificate issues
For anyone who is interested this is how we finally solved the problem: Seems that we couldn't get couchDB to work properly with our intermediate certificate. Since we are running our couchDB server on an AWS EC2 instance, I just created an ELB (Elastic Load Balancer) instance and uploaded my certificates to the ELB, then added the EC2 instance under my load balancer and rerouted my DNS to the load balancer (using Route53 here too). I then turned off SSL completely on couchDB and handed the SSL handshake to the load balancer which supports the use of an intermediate certificate. This does mean that the comms between the ELB and couchDB is insecure but for us that is fine. This also means that we now can add in more couchDB servers under the ELB for scalability so 2 birds 1 stone solut

Getting ssl_error_bad_cert_alert on firefox after installing self signed p12 certificate
The ssl_error_bad_cert_alert error in this case means the server doesn't trust your self-signed cert. One way to solve this is to generate certs and CSR's, and then sign them with a local development CA. Then you just add your dev CA to the JVM truststore. It is slightly more setup, but is more flexible (e.g., you can create signed certs for a whole development team, test revocation via OCSP/CRL, etc). These steps are copied from my history and probably require changes: Create a local dev CA openssl genrsa -out ca.key -aes256 -passout pass:changeit 4096 openssl req -new -x509 -key ca.key -config openssl.conf -days 3560 -sha256 -out ca.pem -passin pass:changeit openssl rsa -in ca.key -out ca.key -passin pass:changeit Generate client and server keystores with a keypair in each keytool

Self signed certificate honoring both, Machine Name & IP Address
You should create a certificate with multiple Subject Alternative Names. What you put in the CN at that stage doesn't really matter (it's only a fallback solution when there are no SANs), but putting the host name should help you identify the certificate in various lists. Note that the entries for host names should be of dNSName type, but the entries for the IP address should be of iPAddress type, so you need a certificate creation tool that supports both. There are more details in this question (not specific to Java). Note that IP addresses can be OK in a development context, but host names are often better anyway. Few (if any) CAs will issue you with a certificate tied to an IP address.

How to create self-signed certificate programmatically for WCF service?
I could not make this work, but I found an alternate solution. (Update December 2014: I have now gotten it to work using the accepted answer.) I was able to use the PluralSight.Crypto library to achieve what I need. I had to modify the source code slightly to get the private key to store in the LocalMachine store. The changes I made were to the file CryptContext.cs. I changed the CreateSelfSignedCertificate method. Following is a snippet of code including the change that I made. In essence, I set the Flags member of the CryptKeyProviderInformation structure to set it to 0x20 (CRYPT_MACHINE_KEYSET) if the CryptContext object contains this value in its Flags. byte[] asnName = properties.Name.RawData; GCHandle asnNameHandle = GCHandle.Alloc(asnName, GCHandleType.Pinned);

Creating a truststore to only validate certificate signed by a custom CA in JAVA
I can only answer part of your questions: The truststore should contain your CA, you can generate it with keytool: http://docs.oracle.com/cd/E19509-01/820-3503/6nf1il6er/index.html No problem you can implement this in android in the same way than in java using java.security.* and org.apache.http.* classes. One warning, for android versions <=2.3, you could need to implement a workaround as some public CA are missing and it doesn't support miss-ordered certificates chains. I can give you more details if needed. I don't know Edit: A good turorial: http://nelenkov.blogspot.com/2011/12/using-custom-certificate-trust-store-on.html

signed jar file-- jnlp fails to prompt user to accept certificate
In answer to your specific questions: It is handled automatically by the jar signer tool, don't sweat the names. The Java version of the server is not relevant, unless the server is compiling the code. But even then, Java apps. should be 'forward compatible'. I.E. an app. compiled in 1.5, should run in 1.5, 1.6 & 1.7.. I don't think the jar signer tool does anything different in the file writing since it was first made, so the version is irrelevant. Irrelevant based on point (3).

If the client and server use the same certificate file for a secure connection over SSL?
The certificate is public information. It's the private key that allows the entity to prove its identity. The client is guaranteed by the SSL/TLS handshake that only the party with the private key matching the public key in the server certificate can be at the other end with the suitable master secret, so as to be able to decipher the communication. The problem it addresses is whether or not the remote party is indeed the one to which the certificate was issued. (This is similar to checking that the picture on the photo ID matches the person in front of you.) Configuration of the certificate (and not the private key) on the client side is there to tell it which certificates you are willing to trust. The problem it addresses is whether or not to trust what the certificate say (in particul

How to generate a secure temporary url to download file from Amazon S3?
Make sure that the expiration time of the link is set to a very short time. Then make sure that you are communicating with the user via SSL, and that the link provided is SSL. When using an SSL connection, both the data from the page and the URL are encrypted, and no one 'sniffing' the data should be able to see anything. The only other way to put a real lock down on a file like that would be to then aggressively check the log files generated by the S3 bucket, and check the link for abuse. The problem however is that the traffic for your link may take several hours to make it into logs, but dependant on how long you want these links to last that time delay may be acceptable. Then assuming you find abuse, such as several different IP addresses hitting the link, you can stop the hits by

Why is my certificate not valid unless I put the Sub CA certificate in the trusted root certificate authorities?
To elaborate on Erik's comment, trusting the Root CA certificate means that you will trust what the Root CA directly signs. If you have an intermediate Sub CA in the middle, its certificate is signed by the Root CA, and the Sub CA signs your certificate directly. Root CA ---signs/verifies---> Sub CA ---signs/verifies---> End user certificate As Erik said, if you do not have the Sub CA certificate present, then there is no way to link the Root CA to the End user certificate. The Root can verify the Sub CA certificate, and the Sub CA can verify the End user certificate, but there is no way for the Root to skip over the Sub CA and verify the End user certificate because the root did not sign the End user certificate. 2 ways to resolve this are: include the Sub CA cert in your tru
