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 for the store which you generated.
• 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 *.crt; 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: From each store you need to remove the DST Root CA X3 which is for your reference in this directory. See file DST Root CA X3.txt in this directory. Apple's file name is IdenTrust_Root_X3.der. For the Microsoft store you have to identify the file beforehand like for f in *.crt; do echo $f >/dev/stderr; openssl x509 -in $f -inform DER -text -noout | grep DST ;done

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. You must use ~/utils/create_ca_hashes.sh for every 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.
