certdump
|
||||||
|
|
||||||
|
Dump a PEM file containing certificates.
|
||||||
|
|
||||||
|
It takes a number of files on the command line which should contain
|
||||||
|
at least one certificate, and dumps the certificates found in those
|
||||||
|
files. If the -l flag is given, it is assumed the file is a bundle and
|
||||||
|
only the leaf certificate will be shown.
|
||||||
|
|
||||||
|
Example (kyleisom.pem and tyrfingr.pem are the bundled certificates
|
||||||
|
for two of my sites):
|
||||||
|
|
||||||
|
$ certdump *.pem
|

--kyleisom.pem ---

fragment
|
||||||
|
|
||||||
|
This is a program to print a fragment of a file. It takes a filename,
|
||||||
|
a starting line (lines are numbered starting at 1) and an optional
|
||||||
|
end line or offset.
|
||||||
|
|
||||||
