openssl - X.509: Private / Public Key -


we're trying implement functionality of web-service 1 of our partners. now, content beeing transmitted, should encrypted public key, have provide.

the security-specification says public-certificate has x.509 standard. doesn't x.509 rely on private / public key method? because 1 .pem file, containing private key, , certificate, no public key, using following command:

openssl req -new -x509 -days 365 -nodes -out ./cert.pem -keyout ./cert.pem

do have modify command in order create private , public key?

the basics command line steps generate private , public key using openssl follow

openssl genrsa -out private.key 1024 openssl req -new -x509 -key private.key -out publickey.cer -days 365 openssl pkcs12 -export -out public_privatekey.pfx -inkey private.key -in publickey.cer

step 1 – generates private key

step 2 – creates x509 certificate (.cer file) containing public key upload when registering private application (or upgrading partner application).

step 3 – export x509 certificate , private key pfx file. if chosen wrapper library uses .pem file sign requests step not required.

hope helps! this answer explains different file extensions.

linux - xterm copying to CLIPBOARD using copy-selection causes automatic updating of CLIPBOARD upon mouse selection -

i've tried various ways coerce xterm (versions 285 , 292) copy selection clipboard clipboard whenever press ctrl-shift-c. promising way far has been, in ~/.xresources, put this: xterm*vt100.translations: #override \ ctrl shift <keypress> c: copy-selection(clipboard) \n\ ctrl shift <keypress> v: insert-selection(clipboard) ctrl-shift-v works perfectly, copying has nuance... if restart xterm, highlighting text puts things in primary clipboard; expected, proper, default behavior. if hit ctrl-shift-c, copies current selection clipboard clipboard. the bug, however, if highlight text after first time pressed ctrl-shift-c, you'll see highlighting copies both primary and clipboard. cannot figure out how stop xterm updating clipboard upon selection... , doesn't make sense me in first place. i said, @ specific point in time, copy selection clipboard... yet starts updating automatically upon selection after doing once... anyone have workaround...
