+This documents the X.509 CAs, certificates, and CRLS used for testing.
+
+Certification authorities
+-------------------------
+
+There are two main CAs for use as trusted roots:
+- test-ca.crt aka "C=NL, O=PolarSSL, CN=PolarSSL Test CA"
+ uses a RSA-2048 key
+ test-ca-sha1.crt and test-ca-sha256.crt use the same key, signed with
+ different hashes.
+- test-ca2*.crt aka "C=NL, O=PolarSSL, CN=Polarssl Test EC CA"
+ uses an EC key with NIST P-384 (aka secp384r1)
+ variants used to test the keyUsage extension
+The files test-ca_cat12 and test-ca_cat21 contain them concatenated both ways.
+
+Two intermediate CAs are signed by them:
+- test-int-ca.crt "C=NL, O=PolarSSL, CN=PolarSSL Test Intermediate CA"
+ uses RSA-4096, signed by test-ca2
+ - test-int-ca-exp.crt is a copy that is expired
+- test-int-ca2.crt "C=NL, O=PolarSSL, CN=PolarSSL Test Intermediate EC CA"
+ uses an EC key with NIST P-384, signed by test-ca
+
+A third intermediate CA is signed by test-int-ca2.crt:
+- test-int-ca3.crt "C=UK, O=mbed TLS, CN=mbed TLS Test intermediate CA 3"
+ uses an EC key with NIST P-256, signed by test-int-ca2
+
+Finally, other CAs for specific purposes:
+- enco-ca-prstr.pem: has its CN encoded as a printable string, but child cert
+ enco-cert-utf8str.pem has its issuer's CN encoded as a UTF-8 string.
+- test-ca-v1.crt: v1 "CA", signs
+ server1-v1.crt: v1 "intermediate CA", signs
+ server2-v1*.crt: EE cert (without of with chain in same file)
+- keyUsage.decipherOnly.crt: has the decipherOnly keyUsage bit set
+
+End-entity certificates
+-----------------------
+
+Short information fields:
+
+- name or pattern
+- issuing CA: 1 -> test-ca.crt
+ 2 -> test-ca2.crt
+ I1 -> test-int-ca.crt
+ I2 -> test-int-ca2.crt
+ I3 -> test-int-ca3.crt
+ O -> other
+- key type: R -> RSA, E -> EC
+- C -> there is a CRL revoking this cert (see below)
+- L -> CN=localhost (useful for local test servers)
+- P1, P2 if the file includes parent (resp. parent + grandparent)
+- free-form comments
+
+List of certificates:
+
+- cert_example_multi*.crt: 1/O R: subjectAltName
+- cert_example_wildcard.crt: 1 R: wildcard in subject's CN
+- cert_md*.crt, cert_sha*.crt: 1 R: signature hash
+- cert_v1_with_ext.crt: 1 R: v1 with extensions (illegal)
+- cli2.crt: 2 E: basic
+- cli-rsa.key, cli-rsa-*.crt: RSA key used for test clients, signed by
+ the RSA test CA.
+- enco-cert-utf8str.pem: see enco-ca-prstr.pem above
+- server1*.crt: 1* R C* P1*: misc *(server1-v1 see test-ca-v1.crt above)
+ *CRL for: .cert_type.crt, .crt, .key_usage.crt, .v1.crt
+ P1 only for _ca.crt
+- server2-v1*.crt: O R: see test-ca-v1.crt above
+- server2*.crt: 1 R L: misc
+- server3.crt: 1 E L: EC cert signed by RSA CA
+- server4.crt: 2 R L: RSA cert signed by EC CA
+- server5*.crt: 2* E L: misc *(except -selfsigned and -ss-*)
+ -sha*: hashes
+ .eku*: extendeKeyUsage (cli/srv = www client/server, cs = codesign, etc)
+ .ku*: keyUsage (ds = signatures, ke/ka = key exchange/agreement)

+Signing CA in parentheses (same meaning as certificates).
+
+- crl-ec-sha*.pem: (2) server6.crt
+- crl-future.pem: (2) server6.crt + unknown
+- crl-rsa-pss-*.pem: (1) server9{,badsign,with-ca}.crt + cert_sha384.crt + unknown
+- crl.pem, crl_expired.pem: (1) server1{,.cert_type,.key_usage,.v1}.crt + unknown
+- crl_md*.pem: crl_sha*.pem: (1) same as crl.pem
+- crt_cat_*.pem: (1+2) concatenations in various orders:
+ ec = crl-ec-sha256.pem, ecfut = crl-future.pem
+ rsa = crl.pem, rsabadpem = same with pem error, rsaexp = crl_expired.pem
+
+Note: crl_future would revoke server9 and cert_sha384.crt if signed by CA 1
+ crl-rsa-pss* would revoke server6.crt if signed by CA 2
+
+Generation
+----------
+
+Newer test files have been generated through commands in the Makefile. The
+resulting files are committed to the repository so that the tests can
+run without having to re-do the generation and so that the output is the
+same for everyone (the generation process is randomized).
+
+The origin of older certificates has not been recorded.
