### 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 (MPL 2.0)
* **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 https://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/had to identify the file beforehand like ``for f in *.crt; do openssl x509 -in $f -inform DER -text -noout | grep -q 'DST' && echo $f ;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>``.
#### License
Please note that the licenses of the certificate stores might not be GPLv2 in all the cases. In general the root and intermediate certificates are free for use -- otherwise the internet wouldn't work. Besides the certificate vendors also browsers use them. Apple and Microsoft however didn't list licenses for those certificates. Microsoft is (as Mozilla and Google) a member of the Common CA Database though, see https://www.ccadb.org/ .
#### 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.
