openssl nseq [-help] [-in filename] [-out filename] [-toseq] [-provider name] [-provider-path path] [-propquery propq]
This command takes a file containing a Netscape certificate sequence and prints out the certificates contained in it or takes a file of certificates and converts it into a Netscape certificate sequence.
A Netscape certificate sequence is an old Netscape-specific format that can be sometimes be sent to browsers as an alternative to the standard PKCS#7 format when several certificates are sent to the browser, for example during certificate enrollment. It was also used by Netscape certificate server.
Print out a usage message.
- -in filename
This specifies the input filename to read or standard input if this option is not specified.
- -out filename
Specifies the output filename or standard output by default.
Normally a Netscape certificate sequence will be input and the output is the certificates contained in it. With the -toseq option the situation is reversed: a Netscape certificate sequence is created from a file of certificates.
- -provider name
- -provider-path path
- -propquery propq
See “Provider Options” in openssl(1), provider(7), and property(7).
Output the certificates in a Netscape certificate sequence
openssl nseq -in nseq.pem -out certs.pem
Create a Netscape certificate sequence
openssl nseq -in certs.pem -toseq -out nseq.pem
