i have created proxy server for mdm application. its working fine with SSL Certificate no issue at all.
But when its come to installing Certificate on Application Side getting this error belw Encrypted Key File Uploaded. Decrypt it and upload again. R
From Centos9 Proxy Server. Copied Files.
But Still not able to install Key File
If you open the key file in a text editor it probably says -----BEGIN ENCRYPTED PRIVATE KEY----- at the top. You need to convert your key file to one that doesn't use a password.
How did you get your certificate (which ACME client?) and where did you get your file that you're using, did you convert it with openssl etc?
You could probably convert what you have (certificate full chain, plus key) into a PFX (p12 file) which is an archive that contains everything in one file.
How to convert? you mean from Centos9 reverse proxy needs to be convert After copying files cert.pem and chain.pem and privkey.pem in to windows any tool to convert?
Ok if you have the key without the password then upload it (your /tmp/server.key file). The problem you were seeing was because the key had a password set.
Don't concern yourself with my PFX comment, that's too complicated and you don't need to do it.
key is in different format which is not supported from ME MDM. we have generated the CSR file, which need to be signed by the vendor and you can upload it back in MDM. Also make sure to upload the server generated key in the attached screenshot.
@webprofusion ManageEngine support said
My ManageEngine is installed in Windows11 VM. CSR is executed from Windows11
MDM Support is saying that. you need to issue the certificate with CSR to Certbot let's encrypt Certificate from reverse proxy server of linux VM.
Now my expectation from Let's Encrypt. How to issue the certificate with CSR.
Please provide me the Steps
As @webprofusion said, you have the Certificate already. You need ManageEngine to help you install it on their product. Tell them you have the Certificate but can not install it.
@jvanasco See my screen shot as i mentioned. which i tried to install Certificate. and Keyfile doesn't take. So manage engine has request. Please issue from lets' encrypt certificate application is installed in Linux Reverse proxy server with Server CSR of where Manage engine is installed in Windows11.
Now i want procedure for how to keep CSR file into my Linux reverse proxy to issue the certificate
Did you specify RSA when you created created the key? Certbot keys have been ECC keys by default for many years now. If you need an RSA key, you must specify that in your command.
