The nseq 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
This specifies the input filename to read or standard input if this
option is not specified.
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.
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
The PEM encoded form uses the same headers and footers as a certificate:
A Netscape certificate sequence is a Netscape specific form that can 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 is used by Netscape certificate server for example.
This program needs a few more options: like allowing DER or PEM input and
output files and allowing multiple certificate files to be used.
