how to print a certificate from CA in text form with openssl

I know how to see certificate files in text form with openssl with the following command:

$ openssl x509 -in example.crt -text -noout

I happened to download a csr file for thawte in the following link: http://tj.symcb.com/tj.crt

And applying the same command to tj.crt results in this error message:

$ openssl x509 -in tj.crt -text
unable to load certificate
140736213377928:error:0906D06C:PEM routines:PEM_read_bio:no start line:/BuildRoot/Library/Caches/com.apple.xbs/Sources/libressl/libressl-22/libressl/crypto/pem/pem_lib.c:704:Expecting: TRUSTED CERTIFICATE

I just want to see who issued the certificate and what not on my own with the command. Any help please?

The file that you provided the link to is not 'csr' - 'certificate signing request' but certificate itself.

When you want to get the information from the certificate in text form then your command is correct, you just need to add -inform DER since the certificate is in binary form instead of PEM format.
