Mangle

Change .p12 password:

openssl pkcs12 -in original.p12 -nodes -clcerts -out temp.pem
openssl pkcs12 -export -in temp.pem -out new.p12

Remove RSA pem password:

openssl rsa -in rsa_key.pem -out rsa_key.clear.pem

Convert .pem to .p12

openssl pkcs12 -export -in client.pem -out client.p12

Split key:

openssl pkcs12 -nokeys -in original.p12 -out client.crt
openssl pkcs12 -nocerts -in original.p12 -out client.key

or without password:

openssl pkcs12 -nocerts -nodes -in original.p12 -out client.key

Merge cert.pem and key.pem to one pem:

openssl pkcs12 -inkey key.pem -in cert.pem -export -out both.p12
openssl pkcs12 -in both.p12 -nodes -clcerts -out both.pem

Re-wrap RSA key in new x509:

cert="./x509_cert.pem"
cert_key="./x509_cert_and_rsa_key.clear.pem"
tmp_key="./key.tmp.pem"
tmp_cert_key="./cert_key.tmp.p12"

ser="$(openssl x509 -in "$cert" -noout -serial | sed -n 's/^serial=\(.*\)$/\1/p')"
ser="$(hextodec "$ser")"
subj="$(openssl x509 -in "$cert" -noout -subject | sed -n 's/^subject= *\(.*\)$/\1/p')"

openssl rsa -in "$cert_key" -out "$tmp_key"
openssl req -batch -x509 -nodes -days 90 -key "$tmp_key" -set_serial "$ser" -subj "$subj" -out "$cert" -new
openssl pkcs12 -inkey "$tmp_key" -in "$cert" -export -passout 'pass:' -out "$tmp_cert_key"
openssl pkcs12 -in "$tmp_cert_key" -passin 'pass:' -clcerts -nodes -out "$cert_key"

Java

Make self-signed server key.

/usr/lib/jvm/java-6-openjdk/bin/keytool -genkey -alias tomcat -keyalg RSA

List Trusted CA Certs.

keytool -list -v -keystore $JAVA_HOME/jre/lib/security/cacerts

Export a certificate from a keystore

keytool -export -alias tomcat -file tomcat.crt -keystore keystore.jks

Import New CA into Trusted Certs

keytool -import -trustcacerts -file tomcat.crt -alias tomcat -keystore truststore

Export private key:

Generate RSA key:

openssl genpkey -out rsa_key_4096.pem -outform PEM -cipher des3 -algorithm RSA -pkeyopt rsa_keygen_bits:4096

Wrap RSA key to x509

openssl req -x509 -days 365 -new -key key_a.private.pem -out test-user-cert.pem
