Converting .crt to .pfx

Hi I am trying to convert .crt which is loaded to f5 to .pfx, i tried this commmand:

 

openssl pkcs12 -export -out /var/tmp/:Common:f5_sharepoint.pfx -inkey /config/filestore/files_d/Common_d/certificate_key_d/:Common:f5_pgpc_sharepoint.key_203294_1 -in /config/filestore/files_d/Common_d/certificate_d/:Common:f5_pgpc_sharepoint.crt_203332_1

 

but i encounter "unable to load certificates" what is my error? thank you!

    Late answer but its still not now documented correctly i think (https://support.f5.com/csp/article/K31936122).
    (edit LiefZimmerman to clarify the KB article was updated)

    The problem is that the certificate files are stored as DER format and have to be converted to PEM format first while the key files already are in PEM format:

    copy files:

    cp /config/filestore/files_d/Common_d/certificate_d/:foo_1: /var/tmp/foo.der
cp /config/filestore/files_d/Common_d/certificate_key_d/:foo_2: /var/tmp/foo.key

    check if DER:

    openssl x509 -in /var/tmp/foo.der -inform DER -text

     if DER, convert to pem:

    openssl x509 -inform DER -outform PEM -text -in /var/tmp/foo.der -out /var/tmp/foo.crt

    create pfx:

    openssl pkcs12 -export -out /var/tmp/foo.pfx -inkey /var/tmp/foo.key -in /var/tmp/foo.crt

    remove files after exported pfx to another machine:

    rm /var/tmp/foo.der
rm /var/tmp/foo.crt
rm /var/tmp/foo.key
rm /var/tmp/foo.pfx

    Hi,

    in bash, add a "\" before ":"

    openssl pkcs12 -export -out /var/tmp/\:Common\:f5_sharepoint.pfx -inkey /config/filestore/files_d/Common_d/certificate_key_d/\:Common\:default.key_19145_1 -in /config/filestore/files_d/Common_d/certificate_d/\:Common\:default.crt_19145_1

      copy files to /var/tmp dir and change names to remove : and try again with those files

    Did you solve this? I have exactly the same problem, cannot convert to pkcs12 due to "unable to load certificates" error. The cert is working correctly on VS.
