I have a poorly named PEM file and I'm not sure if it's even relevant anymore.
For a given PEM file, is it possible to see what the associated URL is?
No, but you can check the Fingerprint and see what server it is on.

I'm working on creating a local image registry for an OKD installation by following along with this Medium article which assumes the creation of
the self-sign CA, server certificate with both the short and fully
qualified hostname of this VM
It calls for
the CA cert, server cert, server key saved as myca.pem,
registry.pem, registry-key.pem
I'm pretty new to certs so I was following the guidance of this article and using cfssl (as recommended by the former article) for generating those. I've gotten through generating and signing the "Intermediate CA". I'm a little unclear on where and how to generate the specific certs the former article requires. I'd really appreciate some clarifications or guidance, if possible, on the following issues.
I believe the ca.pem generated in the first "CA Authority" process in the
latter article is the equivalent of the myca.pem file mentioned in
the former article, but with a different name. Is this the case?
I am unclear where exactly the registry.pem and registry-key.pem
files are generated. Are these just certificates generated using the
"server" profile and assigned the name "registry"? Are they a
completely separate profile I should be adding to the
cfssl.json file? Are they neither?
In whichever case, are there any additional usages I need in the
cfssl.json file or additional config files I need to create in order for it to be suitable for an image registry? Do I
still need to create the additional "host certificate config file" mentioned in
the latter article?
I have tried absorbing as much information about ssl certificates as I could but so far I am unfortunately not finding anything that clears up the specific questions I have. I am sure this is probably simpler than I realize, so any help clarifying what's needed here would be profoundly appreciated. Thanks very much.
I was able to figure this all out. Here are the answers to my three questions:
This was the correct assumption.
These are generated using the "server" profile and given whichever name I choose.
I had to create the additional host certificate config file and point the CN in that file to my local fully qualified domain name. This config file was then used as an argument for generating the certificates.
i have .cert file. .key file and Password pharse and end point. We are using keyStore, we are using file system. How can i pass these in my karate request.
I think you have to convert a .crt file, please read the docs and also this thread (long) may help: https://github.com/intuit/karate/issues/281
Please update here with your findings so that it helps others and you can suggest changes to the docs if required.

EDIT: as per comment below, solution is to create a keystore out of the *.crt file and a .key file, and then use Karate configure ssl to use the keystore.
I have a PPK file and I am trying to have PuTTY use it, when I am connecting to a remote server. But I keep getting this error below, and then I am just asked for my username (while I should be directly allowed in as root).
I don't understand what the problem is, and what's worse I have no idea how to troubleshoot further. A colleague of mine is using the same file and says everything is OK on his side. So I am stuck.
I did a web search and all I find is recommendations to convert the PEM file into a PPK file. But that does not apply in my case, I already have a PPK file.
I am using Windows on my local machine and the PPK file is located in C:\ssh-keys\
Unable to use key file "C:\ssh-keys\filename.ppk" (not a private key)
login as:
Here is the header:
filename.ppk
ё : mBIN ‚Ѓ& PuTTY-User-Key-File-2: ssh-rsa
Encryption: none
Comment: imported-openssh-key

Your key file is corrupted.
A .ppk file must start with the PuTTY-User-Key-File- followed by the ppk format version number. It must be a plain text file. No binary data. No UTF BOM. Your colleague must have a different (correct) copy of the file.
The server mode SSL must use a certificate with the associated private key.
I have my Base64-encoded .crt file and another huge text file with lots of info, from my certificate provider, which includes the private RSA key in an equivalent format.
I tried putting that in a .pvk file to later make the .pfx one, and it didn't work. (nice try, right?)
What do I need to actually do to use this certificate to use SSL in my .NET application?
Edit: Made a proper .pvk, made the .pfx, still, same error.
I finally solved this. I had to use System.Security.Cryptography.X509Certificates.X509Certificate2 with the .pfx file.
The simple X509Certificate didn't seem to work.
I need an access to .k12 or .pem files for all https websites I am visiting on Mac OSx machine. Can anyone help me know the path where these files can be found.
Also, need to know a way to decrypt some packets using the key.
There are a couple of ways to get a certificate file in OSX. One way is to export the certificates from Keychain Access. Select Certificates in the Category (lower left) panel, choose Select All from the Edit menu (or hit ⌘A), and then choose Export Items... from the File menu (or hit ⇧⌘E). You can export your certificates as a .p12 file or a .cer file. The problem with this approach is you have to perform these steps periodically to keep your file in sync with the latest updates from Apple.
Another way is to install OpenSSL and use the cert.pem file that comes with it. Similarly, you'll have to keep OpenSSL up to date.
You would simply access the tool named "Keychain Access" in the Utilities folder of your Applications directory.
Once there, you can filter each keychain to only show certificates.
As for decrypting packets using a given key, there are plenty functions doing that within the Security framework, but this question would require clarification (Language requirement etc).
I was looking for this too. I couldn't find the files anywhere so I thought how about exporting them.
From the Keychain Access:
On left pane, click on the KEYS. On right pane, CTRL-Click on the desired certificate.
The Public key should be exported as a PEM file.
The Private Key should be exported as a P12 file.
The Certificate should be exported as a CRT file.
The Private key export option will as for a passphrase and then the user's keychain password. Upon import you will be asked for this passphrase.
NOTE: The private key, contains the public key.
