Converting pfx to pem - Converting MSFT certificate to PEM

For example:

To convert "x509.PFX.MSFT" provided by WSS4J into PEM (x509cert.pem):
$ keytool -export -alias 16c73ab6-b892-458f-abf5-2f875f74882e -keystore x509.PFX.MSFT -storetype pkcs12 -storepass security -rfc -file c:/temp/x509cert.pem

where "16c73ab6-b892-458f-abf5-2f875f74882e" is the value of "org.apache.ws.security.crypto.merlin.keystore.alias" in the crypto.properties

http://junit.sourceforge.net/doc/faq/faq.htm#running_5

- Junit
-- junit3.8.1 (junit.jar)
-- junit-addons-1.4.jar

copy "junit.jar" and "junit-addons-1.4.jar" to the lib directory where you have ant installed (eg. C:\Program Files\apache-ant-1.6.5-bin\lib\)

If you are running on Eclipse: Windows > Preferences > Ant > Runtime > Ant Home Entries > Add External JARs... > [locate and select "junit.jar" & "junit-addons-1.4.jar"]

Generate a self-signed certificate

(1) generate a certificate of 600 days validity of CN=dims

# ketytool -help# keytool -genkey -keyalg RSA -keysize 1024 -alias fookeystorealias -dname "CN=dims" -validity 600 -keypass password -keystore foo.p12 -storetype PKCS12 -storepass password

For example:
# keytool -genkey -keyalg RSA -keysize 1024 -alias "16c73ab6-b892-458f-abf5-2f875f74882e" -dname "CN=dims" -validity 600 -keypass security -keystore foo.p12 -storetype PKCS12 -storepass security


(2) print foo.p12 to PEM format

# openssl pkcs12 -help
# openssl pkcs12 -in foo.p12

(3) save PEM

# cat > foo.pem

copy and pasted output

-----BEGIN CERTIFICATE-----

…

-----END CERTIFICATE-----

from "openssl pkcs12 -in foo.p12" then save.

(4) print the pem to verify

# openssl x509 -in foo.pem -noout -text
