### 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:__ Clone https://github.com/apple-oss-distributions/security_certificates.git, cd to ``security_certificates/certificates/roots``, ``for f in *.* do echo $f >/dev/stderr; openssl x509 -in $f -inform DER -outform PEM ;done >/tmp/Apple.pem``
|
|
|
|
Google Chromium uses basically the trust stores above, see https://www.chromium.org/Home/chromium-security/root-ca-policy.
|
|
|
|
**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``. As of July 2024 this seemed to be needed only for the Microsoft CA store. Apple's file name in 2023 was ``IdenTrust_Root_X3.der``. For the Microsoft CA store you can identify the file beforehand like ``for f in *.crt; do openssl x509 -in $f -inform DER -text -noout | grep -q 'DST' && echo $f ;done`` or use a line from ``DST Root CA X3.txt`` and grep for that in the resulting ``Microsoft.pem``.
|
|
|
|
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>``.
|
|
|
|
IMPORTANT: After updating any of the CA root stores you have to invoke ``./utils/create_ca_hashes.sh`` to update ``~/etc/ca_hashes.txt``.
|

|
#### 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. You MUST
|
|
use ``./utils/create_ca_hashes.sh`` for every Root CA store update, see above.
|
|
|
|
* ``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.
