concat server SSL cert and chain cert

LYC · 07-20-2015, 02:22 AM

Hi,

I have to concat the SSL server cert and chain cert into 1 file. After the concatenation, the content of the file is as follows:

-----BEGIN CERTIFICATE-----
:
-----END CERTIFICATE----------BEGIN CERTIFICATE-----
:
-----END CERTIFICATE-----

Is there any command or work around so that the output is as follows?

-----BEGIN CERTIFICATE-----
:
-----END CERTIFICATE-----
-----BEGIN CERTIFICATE-----
:
-----END CERTIFICATE-----

Thanks in advance

It's a text file. Just use vim or so to add the newline.

Or in a script:

Code:

cp cert1 newcert
echo >> newcert
cat cert2 >> newcert

I will leave it up to more knowledgeable LQers to find more elegant ways or oneliners, but this should work.

the Accepted format is

Code:

-----END CERTIFICATE-----
-----BEGIN CERTIFICATE-----

Exactly 5 hyphens (or dashes) with no whitespace.
so, adjust below
"-----END CERTIFICATE-----<cr>-----BEGIN CERTIFICATE-----"
to match accepted format.

I don't believe whitespace matters in between each stanza.
So, what berndbausch suggests is accurate,
but

Code:

cat file1 file2 > newfile

works also
