How do I make my own bundle file from CRT files? Print this Article
You may do this using you favorite text editor or by using the command line.
Example:
Windows or DOS:
Example:
| # Root CA Certificate - AddTrustExternalCARoot.crt # Intermediate CA Certificate 1 - UTNAddTrustSGCCA.crt # Intermediate CA Certificate 2 - ComodoUTNSGCCA.crt # Intermediate CA Certificate 3 - EssentialSSLCA_2.crt # Your SSL Certificate - yourDomain.crt |
Note: You will not need your SSL certificate for this exercise.
GUI Text Editor
- Open All files in a text editor. (Remember, not your domain certificate.)
- Create a new blank text file.
- Copy contents of all files in reverse order and paste them into the new file.
Example: Intermediate 3, Intermediate 2, Intermediate 1, Root Certificate. - Save newly created file as 'yourDomain.ca-bundle'.
Command Line
Linux or UNIX-like Operating Systems:
| -- cat EssentialSSLCA_2.crt ComodoUTNSGCCA.crt UTNAddTrustSGCCA.crt AddTrustExternalCARoot.crt > yourDomain.ca-bundle |
Windows or DOS:
| -- copy EssentialSSLCA_2.crt + ComodoUTNSGCCA.crt + UTNAddTrustSGCCA.crt + AddTrustExternalCARoot.crt yourDomain.ca-bundle |
