For step +by step instructions, see the HOWTO: + +http://openvpn.net/howto.html + +INSTALL + +1. Edit vars. +2. Set KEY_CONFIG to point to the openssl.cnf file + included in this distribution. +3. Set KEY_DIR to point to a directory which will + contain all keys, certificates, etc. This + directory need not exist, and if it does, + it will be deleted with rm -rf, so BE + CAREFUL how you set KEY_DIR. +4. (Optional) Edit other fields in vars + per your site data. You may want to + increase KEY_SIZE to 2048 if you are + paranoid and don't mind slower key + processing, but certainly 1024 is + fine for testing purposes. KEY_SIZE + must be compatible across both peers + participating in a secure SSL/TLS + connection. +5 . vars +6. ./clean-all +7. As you create certificates, keys, and + certificate signing requests, understand that + only .key files should be kept confidential. + .crt and .csr files can be sent over insecure + channels such as plaintext email. +8. You should never need to copy a .key file + between computers. Normally each computer + will have its own certificate/key pair. + +BUILD YOUR OWN ROOT CERTIFICATE AUTHORITY (CA) CERTIFICATE/KEY + +1. ./build-ca +2. ca.crt and ca.key will be built in your KEY_DIR + directory + +BUILD AN INTERMEDIATE CERTIFICATE AUTHORITY CERTIFICATE/KEY (optional) + +1. ./build-inter inter +2. inter.crt and inter.key will be built in your KEY_DIR + directory and signed with your root certificate. + +BUILD DIFFIE-HELLMAN PARAMETERS (necessary for +the server end of a SSL/TLS connection). + +1. ./build-dh + +BUILD A CERTIFICATE SIGNING REQUEST (If +you want to sign your certificate with a root +certificate controlled by another individual +or organization, or residing on a different machine). + +1. Get ca.crt (the root certificate) from your + certificate authority. Though this + transfer can be over an insecure channel, to prevent + man-in-the-middle attacks you must confirm that + ca.crt was not tampered with. Large CAs solve this + problem by hardwiring their root certificates into + popular web browsers. A simple way to verify a root + CA is to call the issuer on the telephone and confirm + that the md5sum or sha1sum signatures on the ca.crt + files match (such as with the command: "md5sum ca.crt"). +2. Choose a name for your certificate such as your computer + name. In our example we will use "mycert". +3. ./build-req mycert +4. You can ignore most of the fields, but set + "Common Name" to something unique such as your + computer's host name. Leave all password + fields blank, unless you want your private key + to be protected by password. Using a password + is not required -- it will make your key more secure + but also more inconvenient to use, because you will + need to supply your password anytime the key is used. + NOTE: if you are using a password, use ./build-req-pass + instead of ./build-req +5. Your key will be written to $KEY_DIR/mycert.key +6. Your certificate signing request will be written to + to $KEY_DIR/mycert.csr +7. Email mycert.csr to the individual or organization + which controls the root certificate. This can be + done over an insecure channel. +8. After the .csr file is signed by the root certificate + authority, you will receive a file mycert.crt + (your certificate). Place mycert.crt in your + KEY_DIR directory. +9. The combined files of mycert.crt, mycert.key, + and ca.crt can now be used to secure one end of + an SSL/TLS connection. + +SIGN A CERTIFICATE SIGNING REQUEST + +1. ./sign-req mycert +2. mycert.crt will be built in your KEY_DIR + directory using mycert.csr and your root CA + file as input. + +BUILD AND SIGN A CERTIFICATE SIGNING REQUEST +USING A LOCALLY INSTALLED ROOT CERTIFICATE/KEY -- this +script generates and signs a certificate in one step, +but it requires that the generated certificate and private +key files be copied to the destination host over a +secure channel. + +1. ./build-key mycert (no password protection) +2. OR ./build-key-pass mycert (with password protection) +3. OR ./build-key-pkcs12 mycert (PKCS #12 format) +4. OR ./build-key-server mycert (with nsCertType=server) +5. mycert.crt and mycert.key will be built in your + KEY_DIR directory, and mycert.crt will be signed + by your root CA. If ./build-key-pkcs12 was used a + mycert.p12 file will also be created including the + private key, certificate and the ca certificate. + +IMPORTANT + +To avoid a possible Man-in-the-Middle attack where an authorized +client tries to connect to another client by impersonating the +server, make sure to enforce some kind of server certificate +verification by clients. There are currently four different ways +of accomplishing this, listed in the order of preference: + +(1) Build your server certificates with the build-key-server + script. This will designate the certificate as a + server-only certificate by setting nsCertType=server. + Now add the following line to your client configuration: + + ns-cert-type server + + This will block clients from connecting to any + server which lacks the nsCertType=server designation + in its certificate, even if the certificate has been + signed by the CA which is cited in the OpenVPN configuration + file (--ca directive). + +(2) Use the --tls-remote directive on the client to + accept/reject the server connection based on the common + name of the server certificate. + +(3) Use a --tls-verify script or plugin to accept/reject the + server connection based on a custom test of the server + certificate's embedded X509 subject details. + +(4) Sign server certificates with one CA and client certificates + with a different CA. The client config "ca" directive should + reference the server-signing CA while the server config "ca" + directive should reference the client-signing CA. + +NOTES + +Show certificate fields: + openssl x509 -in cert.crt -text diff --git a/easy-rsa/1.0/build-ca b/easy-rsa/1.0/build-ca new file mode 100755 index 0000000..5ad59cc --- /dev/null +++ b/easy-rsa/1.0/build-ca @@ -0,0 +1,13 @@ +#!/bin/sh + +# +# Build a root certificate +# + +if test $KEY_DIR; then + cd $KEY_DIR && \ + openssl req -days 3650 -nodes -new -x509 -keyout ca.key -out ca.crt -config $KEY_CONFIG && \ + chmod 0600 ca.key +else + echo you must define KEY_DIR +fi diff --git a/easy-rsa/1.0/build-dh b/easy-rsa/1.0/build-dh new file mode 100755 index 0000000..6de4baf --- /dev/null +++ b/easy-rsa/1.0/build-dh @@ -0,0 +1,12 @@ +#!/bin/sh + +# +# Build Diffie-Hellman parameters for the server side +# of an SSL/TLS connection. +# + +if test $KEY_DIR; then + openssl dhparam -out ${KEY_DIR}/dh${KEY_SIZE}.pem ${KEY_SIZE} +else + echo you must define KEY_DIR +fi diff --git a/easy-rsa/1.0/build-inter b/easy-rsa/1.0/build-inter new file mode 100755 index 0000000..8b3a6b2 --- /dev/null +++ b/easy-rsa/1.0/build-inter @@ -0,0 +1,19 @@ +#!/bin/sh + +# +# Make an intermediate CA certificate/private key pair using a locally generated +# root certificate. +# + +if test $# -ne 1; then + echo "usage: build-inter <name>"; + exit 1 +fi + +if test $KEY_DIR; then + cd $KEY_DIR && \ + openssl req -days 3650 -nodes -new -keyout $1.key -out $1.csr -config $KEY_CONFIG && \ + openssl ca -extensions v3_ca -days 3650 -out $1.crt -in $1.csr -config $KEY_CONFIG +else + echo you must define KEY_DIR +fi diff --git a/easy-rsa/1.0/build-key b/easy-rsa/1.0/build-key new file mode 100755 index 0000000..3159d2b --- /dev/null +++ b/easy-rsa/1.0/build-key @@ -0,0 +1,20 @@ +#!/bin/sh + +# +# Make a certificate/private key pair using a locally generated +# root certificate. +# + +if test $# -ne 1; then + echo "usage: build-key <name>"; + exit 1 +fi + +if test $KEY_DIR; then + cd $KEY_DIR && \ + openssl req -days 3650 -nodes -new -keyout $1.key -out $1.csr -config $KEY_CONFIG && \ + openssl ca -days 3650 -out $1.crt -in $1.csr -config $KEY_CONFIG && \ + chmod 0600 $1.key +else + echo you must define KEY_DIR +fi diff --git a/easy-rsa/1.0/build-key-pass b/easy-rsa/1.0/build-key-pass new file mode 100755 index 0000000..03ab304 --- /dev/null +++ b/easy-rsa/1.0/build-key-pass @@ -0,0 +1,20 @@ +#!/bin/sh + +# +# Similar to build-key, but protect the private key +# with a password. +# + +if test $# -ne 1; then + echo "usage: build-key-pass <name>"; + exit 1 +fi + +if test $KEY_DIR; then + cd $KEY_DIR && \ + openssl req -days 3650 -new -keyout $1.key -out $1.csr -config $KEY_CONFIG && \ + openssl ca -days 3650 -out $1.crt -in $1.csr -config $KEY_CONFIG && \ + chmod 0600 $1.key +else + echo you must define KEY_DIR +fi diff --git a/easy-rsa/1.0/build-key-pkcs12 b/easy-rsa/1.0/build-key-pkcs12 new file mode 100755 index 0000000..f8a057b --- /dev/null +++ b/easy-rsa/1.0/build-key-pkcs12 @@ -0,0 +1,21 @@ +#!/bin/sh + +# +# Make a certificate/private key pair using a locally generated +# root certificate and convert it to a PKCS #12 file including the +# the CA certificate as well. + +if test $# -ne 1; then + echo "usage: build-key-pkcs12 <name>"; + exit 1 +fi + +if test $KEY_DIR; then + cd $KEY_DIR && \ + openssl req -days 3650 -nodes -new -keyout $1.key -out $1.csr -config $KEY_CONFIG && \ + openssl ca -days 3650 -out $1.crt -in $1.csr -config $KEY_CONFIG && \ + openssl pkcs12 -export -inkey $1.key -in $1.crt -certfile ca.crt -out $1.p12 && \ + chmod 0600 $1.key $1.p12 +else + echo you must define KEY_DIR +fi diff --git a/easy-rsa/1.0/build-key-server b/easy-rsa/1.0/build-key-server new file mode 100755 index 0000000..30dc41e --- /dev/null +++ b/easy-rsa/1.0/build-key-server @@ -0,0 +1,22 @@ +#!/bin/sh + +# +# Make a certificate/private key pair using a locally generated +# root certificate. +# +# Explicitly set nsCertType to server using the "server" +# extension in the openssl.cnf file. + +if test $# -ne 1; then + echo "usage: build-key-server <name>"; + exit 1 +fi + +if test $KEY_DIR; then + cd $KEY_DIR && \ + openssl req -days 3650 -nodes -new -keyout $1.key -out $1.csr -extensions server -config $KEY_CONFIG && \ + openssl ca -days 3650 -out $1.crt -in $1.csr -extensions server -config $KEY_CONFIG && \ + chmod 0600 $1.key +else + echo you must define KEY_DIR +fi diff --git a/easy-rsa/1.0/build-req b/easy-rsa/1.0/build-req new file mode 100755 index 0000000..30f62f5 --- /dev/null +++ b/easy-rsa/1.0/build-req @@ -0,0 +1,18 @@ +#!/bin/sh + +# +# Build a certificate signing request and private key.

For compatibility, all previous scripts from 1.0 such + as build-key and build-key-server are provided as stubs + which call pkitool to do the real work. + +* pkitool has a --batch flag (enabled by default) which generates + keys/certs without needing any interactive input. pkitool + can still generate certs/keys using interactive prompting by + using the --interact flag. + +* The inherit-inter script has been provided for creating + a new PKI rooted on an intermediate certificate built within a + higher-level PKI. See comments in the inherit-inter script + for more info. + +* The openssl.cnf file has been modified. pkitool will not + work with the openssl.cnf file included with previous + easy-rsa releases. + +* The vars file has been modified -- the following extra + variables have been added: EASY_RSA, CA_EXPIRE, + KEY_EXPIRE. + +* The make-crl and revoke-crt scripts have been removed and + are replaced by the revoke-full script. + +* The "Organizational Unit" X509 field can be set using + the KEY_OU environmental variable before calling pkitool. + +* This release only affects the Linux/Unix version of easy-rsa. + The Windows version (written to use the Windows shell) is unchanged. + +INSTALL easy-rsa 1.
