(Ruby) Convert Java KeyStore to PKCS12 / PFX
Loads a Java keystore file and saves it as a PKCS12 / PFX. A Java keystore (JKS) can contain two types of entries: (1) trusted root certificates or (2) private keys + cert chains. Usually a JKS will contain all entries of one type or another (and thus a particular JKS serves one purpose or another; meaning that a JKS containing trusted roots is used as a source for verifying pre-trusted roots, and a JKS containing private keys (and cert chains) is used as a secure, encrypted store for private keys).
A PKCS12 / PFX typically contains one or more private keys, along with each private key's certificate chain. Therefore, it typically makes sense to only write the private key entries to a PKCS12 (and the associated certificate chains). If a JKS contains trusted root certificates, it makes more sense to conver it to a PEM file (such as the CA cert bundle in PEM format from mozilla.org).
require 'chilkat' # This requires the Chilkat API to have been previously unlocked. # See Global Unlock Sample for sample code. jks = Chilkat::CkJavaKeyStore.new() jksPassword = "myJksPassword" # Load the Java keystore from a file. The JKS file password is used # to verify the keyed digest that is found at the very end of the keystore. # It verifies that the keystore has not been modified. success = jks.LoadFile(jksPassword,"/someDir/keyStore.jks") if (success != true) print jks.lastErrorText() + "\n"; exit end # To convert, we'll access the private key entries # from the JKS, add each to the PKCS12, and then save the PKCS12. pkcs12 = Chilkat::CkPfx.new() numPrivateKeys = jks.get_NumPrivateKeys() # For each private key entry, get the private key and # the associated certificate chain. # Each private key is password protected. Usually it is the same # password as used for the keyed digest of the entire JKS. # However, this does not have to be. The password is passed # here to handle the possibility of each private key requiring # a different password. i = 0 while i < numPrivateKeys # privKey is a CkPrivateKey privKey = jks.GetPrivateKey(jksPassword,i) print jks.getPrivateKeyAlias(i) + "\n"; # certChain is a CkCertChain certChain = jks.GetCertChain(i) # Add the private key and it's associated certificate chain to the PKCS12. success = pkcs12.AddPrivateKey(privKey,certChain) if (success != true) print pkcs12.lastErrorText() + "\n"; exit end i = i + 1 end # Save the PKCS12 / PFX to a file. # The password can be the same as the JKS password, or something new. # (With the PKCS12 format, there is a single password for the entire contents # of the file. With the JKS format, there is flexibility in allowing each private key # to have it's own password.) pkcs12Password = "myNewPassword" success = pkcs12.ToFile(pkcs12Password,"/pkcs12_files/myPfx.p12") if (success != true) print pkcs12.lastErrorText() + "\n"; else print "Successfully saved to PKCS12 format." + "\n"; end
