Using a CR-LF encoded file and running `ssl-cert-check -f filename` currently results in invalid PORT parsing and later failing `openssl` command as half the command is truncated due to endline in the middle of the string. (`$2` has CR-LF char)
The only visible error is `ERROR: The file named /var/tmp/cert.XXXXX is unreadable or doesn't exist` but after some debuging I found out that `"${OPENSSL}" s_client $OPTIONS 2> "${ERROR_TMP}" 1> "${CERT_TMP}"` resulted in empty tmp file due to `$OPTIONS` being truncated .
We can make the script compatible with CR-LF input files by removing `\r` from the parsed line.
Should not be a breaking change

Current issue

but after some debuging I found out that
"${OPENSSL}" s_client $OPTIONS 2> "${ERROR_TMP}" 1> "${CERT_TMP}"fails withThis is due to
$OPTIONSbeing truncated as the$2variable inside it has a CR-LF char, so the command passed to openssl has invalid syntax.Here's what
$OPTIONSlook like with CR-LF input file :"-servername host.domain.local"the first half of the command is truncated (
"-connect ${1}:${2}")Fix
We can make the script compatible with CR-LF input files by removing
\rfrom the parsed line.some issues mention this error, I guess they were running the command against CR-LF input file.
Should not be a breaking change, I tried with CR-LF and LF encoded file, both works with this fix.
