In parse_cmd_line() error messages are usually printed to stderr, but in three places the messages are printed to stdout. This commit modifies those three lines so that they also print to stderr.
The commit also replaces a call to a non-existant function, tmln_magenta_term, with a call to tmln_magenta.
Respect changed HSTS epoch time of 180 days.
(DROWN output is changed too as the certificated changed but doesn't matter
as the travis check filters that)
There was by mistake a 179 days threshold and also the error message
was wrong when HSTS was exactly set to 179 days.
This commit sets it to 180 days and corrects the error messages on
both screen and JSON.
This commit addresses a few issued related to the use of testssl.sh with OpenSSL 3.0.0-alpha14.
First, when pkey is used to print a DH key that uses an unknown group, OpenSSL 3.0.0-alpha14 labels the prime and generator using "P:" and "G:" rather than "prime:" and "generator:". (In PR #1586 it was noted that OpenSSL 3.0.0-alpha1 used "prime P:" and "generator G:". The x509 command in OpenSSL 3.0.0-alpha14 still uses "prime P:" and "generator G:" when printing a DH public key in a certificate, but the pkey command just uses "P:" and "G:").
Second, when the pkey command is used to print a DH key that uses certain common primes (e.g., groups from RFC 3526 or RFC 7919), OpenSSL 3.0.0-alpha14 simply prints "GROUP: " followed by a short name for the group rather than printing the value of the prime and generator.
Finally, the "-text" option no longer works if the input is a public key. Fortunately, the "-text_pub" option provides the expected results with all versions of OpenSSL and LibreSSL.
xxd is not a strict requirement and a fallback logic exists to handle its absence. However it is in general more performant and helpful in debugging as well which is desirable in many situations like ci/cd pipelines. See commit 3756cdc for details
This commit makes some minor improvements to code that converts ASCII-HEX to binary.
First, testssl.sh currently has two functions that do the same thing: asciihex_to_binary() and hex2ascii(). This commit all calls to either of these functions with calls to hex2binary(), which is based on the current asciihex_to_binary().
This commit also changes direct use of printf to calls to hex2ascii() in generate-ccm-counter-blocks(), ccm-compute-tag(), and generate_gcm_counter().
Finally, this commit cleans up the implemention of hex2binary() a bit and introduces the option to use xxd, if that program is available. Using xxd rather than multiple calls to printf has a couple of advantages. xxd is a bit faster. However, the primary advantage is that when debugging (i.e., using bash -x), each call to hex2binary() only includes a few steps, regardless of how long the string is, whereas using printf the call to hex2binary() could take hundreds of steps.
