Hi, Thank you for letting us know the problem is solved and for giving us the solution. Regards From: mwvdberg via sap-basis [mailto:sap-basis Groups. The files will be written to the same directory as the script.

This script also writes an information file, so you can inspect the new certificate and verify the SAN is set properly. If you are using Apache, then you can reference the above certificate in your configuration file like so:. And my solution was to create a Root certificate and signed a child certificate by it. So step by step. Because the idea is to sign the child certificate by root and get a correct certificate. The ca. This file must be present and contain a valid serial number.

You may ask, why so difficult, why we must create one more config to sign child certificate by root. If we sign the child certificate by "openssl x" utils, the Root certificate will delete the SAN field in child certificate. So we use "openssl ca" instead of "openssl x" to avoid the deleting of the SAN field. In terminal you can see a sentence with the word "Database", it means file index.

It will contain all information by all certificates you create by "openssl ca" util. To check the certificate valid use:.

This also works in Chrome 57, as it provides the SAN, without having another configuration file. It was taken from an answer here. This creates a single. You can move them to separate. However, the warnings are displayed, because the browser was not able to verify the identify by validating the certificate with a known Certificate Authority CA.

As this is a self-signed certificate there is no CA and you can safely ignore the warning and proceed. Should you want to get a real certificate that will be recognizable by anyone on the public Internet then the procedure is below. MySQL might be denied read access to your certificate file if it is not in apparmors configuration.

Your MySQL server version may not support the default rsa format. Check if local server supports SSL :. Verifying a connection to the database is SSL encrypted :. Require ssl for specific user's connection 'require ssl' :. To connect, the client must specify the --ssl-ca option to authenticate the server certificate, and may additionally specify the --ssl-key and --ssl-cert options. If neither --ssl-ca option nor --ssl-capath option is specified, the client does not authenticate the server certificate.

One liner FTW. I like to keep it simple. Why not use one command that contains ALL the arguments needed? This is how I like it - this creates an x certificate and its PEM key:. That single command contains all the answers you would normally provide for the certificate details. This way you can set the parameters and run the command, get your output - then go for coffee. As has been discussed in detail, self-signed certificates are not trusted for the Internet. You can add your self-signed certificate to many but not all browsers.

Alternatively you can become your own certificate authority. That cost is easy to justify if you are processing credit card payments or work for the profit center of a highly profitable company.

It is more than many can afford for a personal project one is creating on the internet, or for a non-profit running on a minimal budget, or if one works in a cost center of an organization -- cost centers always try to do more with less.

An alternative is to use certbot see about certbot. I did this over the weekend for my organization. I installed the required packages for certbot on my server Ubuntu One likely needs a DNS plugin for certbot - we are presently using DigitalOcean though may be migrating to another service soon.

Note that some of the instructions were not quite right and took a little poking and time with Google to figure out. This took a fair amount of my time the first time but now I think I could do it in minutes. You need to have or generate a personal access token read and write for DigitalOcean's API -- this is a 65 character hexadecimal string.

This string then needs to be put into a file on the webserver from which you are running certbot. That file can have a comment as its first line comments start with. The seccond line is:. Note that one does not have to setup a wildcard certificate, one may instead specify each domain and sub-domain that one wants the certificate to appply to.

It was the wildcard certificate that required the credentials INI file that contained the personal access token from DigitalOcean. Note that public key certificates also known as identity certificates or SSL certificates expire and require renewal. Thus you will need to renew your certificate on a periodic reoccurring basis. The certbot documentation covers renewing certificates.

My plan is to write a script to use the openssl command to get my certificate's expiration date and to trigger renewal when it is 30 days or less until it expires. I will then add this script to cron and run it once per day. I don't like to mess with config files. Stack Overflow for Teams — Collaborate and share knowledge with a private group.

Self-signed certificates are considered insecure for the Internet. Firefox will treat the site as having an invalid certificate, while Chrome will act as if the connection was plain HTTP. More details: gerv. You need to import your CA certificate into your browsers and tell the browsers you trust the certificate -or- get it signed by one of the big money-for-nothing organizations that are already trusted by the browsers -or- ignore the warning and click past it.

I like the last option myself. You should not use the "stock" OpenSSL settings like that. There's no way to avoid using the SAN. See answer below. In addition to jww 's comment. Show 1 more comment. Active Oldest Votes. You can do that in one command: openssl req -x -newkey rsa -keyout key.

Improve this answer. Hongli Diego Woitasen Diego Woitasen For anyone who's interested, here is the documentation , if you want to verify anything yourself. How does signing with a 3rd-party provide more security? JamesMills I mean, think about it -- if a shady looking guy with "free candy" written on the side of his van invites you to come inside, you're totally going to think twice and be on guard about it -- but if someone you trust -- like really trust -- is all like, "naw man, he's legit" you're going to be all about that free candy.

Remember to use -sha to generate SHAbased certificate. Show 26 more comments. The best way to avoid this is: Create your own authority i. How to create a self-signed certificate with OpenSSL The commands below and the configuration file create a self-signed certificate it also shows you how to create a signing request. But usually you don't want them or need them in production. You may need them for development. Create a self signed certificate notice the addition of -x option : openssl req -config example-com.

Its sort of a mashup. For example, RFC does not provide emailAddress. IPv4 localhost IP. Community Bot 1 1 1 silver badge. Particularly sub-sub domains. I have a question referencing this answer here: serverfault. I've just replied to his specific question. I think doesn't make sense to add this long security description when the answer was so simple — Diego Woitasen.

The reason it is not correct is discussed in the long post you don't want to read : — jww. I found your post very helpful. I didn't check if this is in the standard or not. Thank you jww. You said, "1. Create your own authority i. Install the CA certificate on the client". If the root key became compromised, a malicious person could sign a cert for any domain with that key, and if they trick you into going to their website, they can now do a man-in-the-middle attack. Is there a way to create the root CA such that it can only sign intermediary CAs and not certificates?

Then you can protect your intermediary CA with a name constraint. Show 3 more comments. The following files are generated: Private key: example. Remark 1: Crypto parameters Since the certificate is self-signed and needs to be accepted by users manually, it doesn't make sense to use a short expiration or weak cryptography. Remark 2: Parameter " -nodes " Theoretically you could leave out the -nodes parameter which means "no DES encryption" , in which case example.

Remark 3: See also Provide subjectAltName to openssl directly on command line How to add multiple email adresses to an SSL certificate via the command line? I tried to use the oneliner 2 modern on windows in mingw64, and I faced a bug with -subj parameter. Just in case someone is struggling with this one. FranklinYu Are you sure that rsa will be enough in 10 years from now? Because that's the validity period.

As explained, it doesn't make sense to use short expiration or weak crypto. Most bit RSA keys have a validity period of years at most. Regarding OpenSSL 1. Well done! Thanks a lot! I really would like to see a reference that explains in simple terms why this is evolving at such pace. Part of me wonders if it's just because the idea of creating self signed certs is counter productive to the big tech cos.

What is going to be needed in 10 or 20 years time? It's madness, and it's a testament of that the amount of activity this kind of questions on openssl generates.

For example, -days XXX becomes -days if you want your cert to be valid for days. See the docs for more. Thanks for adding the documentation. Add a comment.
