How to create own Bundle file from CRT Files

How do I make my own bundle file from CRT files?

Answer: You may do this using your favourite text editor or by using the command line.


# Root CA Certificate – AddTrustExternalCARoot.crt
# Intermediate CA Certificate 1 – ComodoRSAAddTrustCA.crt OR ComodoECCAddTrustCA.crt
# Intermediate CA Certificate 2 – ComodoRSADomain/Organization/ExtendedvalidationSecureServerCA.crt OR ComodoRSAECCDomain/Organization/ExtendedvalidationSecureServerCA.crt
# Intermediate CA Certificate 3 – ComodoSHA256SecureServerCA.crt
# Your SSL Certificate – yourDomain.crt

Note: You will not need your SSL certificate for this exercise.


There are two ways to create ca bundle file.

1.Using GUI Text Editor

1. Open All files in a text editor. (Remember, not your domain certificate.)
2. Create a new blank text file.
3. Copy contents of all files in reverse order and paste them into the new file.
Example: Intermediate 3, Intermediate 2, Intermediate 1, Root Certificate.
4. Save the newly created file as ‘‘ or ‘’.


2.Using Command Line

Linux or UNIX-like Operating Systems:
cat ComodoRSAAddTrustCA.crt ComodoRSADomain/Organization/ExtendedvalidationSecureServerCA.crt AddTrustExternalCARoot.crt >


cat ComodoSHA256SecureServerCA.crt AddTrustExternalCARoot.crt >

Windows or DOS:
copy ComodoRSAAddTrustCA.crt + ComodoRSADomain/Organization/ExtendedvalidationSecureServerCA.crt + AddTrustExternalCARoot.crt


— copy ComodoSHA256SecureServerCA.crt + AddTrustExternalCARoot.crt‘ is only a placeholder file name. You may call it anything you want.
