Certificate stores

The certificate trust stores were retrieved from

• Linux: Copied from an up-to-date Debian Linux machine
• Mozilla: https://curl.haxx.se/docs/caextract.html
• Java: extracted (keytool -list -rfc -keystore lib/security/cacerts | grep -E -v '^$|^\*\*\*\*\*|^Entry |^Creation |^Alias ') from a JDK LTS version from https://jdk.java.net/. (use dos2unix).
• Microsoft: Following command pulls all certificates from Windows Update services: CertUtil -syncWithWU -f -f . (see also http://aka.ms/RootCertDownload, https://technet.microsoft.com/en-us/library/dn265983(v=ws.11).aspx#BKMK_CertUtilOptions). They are in DER format. Convert them like for f in *.cer; do echo $f >/dev/stderr; openssl x509 -in $f -inform DER -outform PEM ;done >/tmp/Microsoft.pem
• Apple:
  1. System: from Apple OS X keychain app. Open Keychain Access utility, i.e. In the Finder window, under Favorites --> "Applications" --> "Utilities" (OR perform a Spotlight Search for "Keychain Access") --> "Keychain Access" (2 click). In that window --> "Keychains" --> "System Root" --> "Category" --> "All Items" Select all CA certificates except for "Developer ID Certification Authority", omit expired ones, "File" --> "Export Items"
  2. Internet: Pick the latest subdir (=highest number) from https://opensource.apple.com/source/security_certificates/. They are in all DER format despite their file extension. Download them with wget --level=1 --cut-dirs=5 --mirror --convert-links --adjust-extension --page-requisites --no-parent https://opensource.apple.com/source/security_certificates/security_certificates-<latest>/certificates/roots/. Then: for f in *.cer *.der *.crt; do echo $f >/dev/stderr; openssl x509 -in $f -inform DER -outform PEM ;done >/tmp/Apple.pem

Attention: You need to remove the DST Root CA X3 which is for your reference in this directory.

Google Chromium uses basically the trust stores above, see https://www.chromium.org/Home/chromium-security/root-ca-policy.

If you want to check trust against e.g. a company internal CA you need to use ./testssl.sh --add-ca companyCA1.pem,companyCA2.pem <further_cmds> or ADDTL_CA_FILES=companyCA1.pem,companyCA2.pem ./testssl.sh <further_cmds>.

Further files

• tls_data.txt contains lists of cipher suites and private keys for sockets-based tests

• cipher-mapping.txt contains information about all of the cipher suites defined for SSL/TLS

• curves-mapping.txt contains information about all of the elliptic curves defined by IANA

• ca_hashes.txt is used for HPKP test in order to have a fast comparison with known CAs. Use ~/utils/create_ca_hashes.sh for an update

• common-primes.txt is used for LOGJAM and the PFS section

• client-simulation.txt / client-simulation.wiresharked.txt are as the names indicate data for the client simulation. The first one is derived from ~/utils/update_client_sim_data.pl, and manually edited to sort and label those we don't want. The second file provides more client data retrieved from wireshark captures and some instructions how to do that yourself.

• SSLSocketClient.java as the name indicates is a simple socket client in Java to generate a TLS/SSL handshake. It's taken from https://docs.oracle.com/javase/10/security/sample-code-illustrating-secure-socket-connection-client-and-server.htm . It's not ours and it's not GPLv2. There wasn't any license mentioned, it's only added for your convenience.
