Step-by-Step instructions on transferring SSL certificate between servers.<\/h2>\n

Of all of the server to server SSL Certificate transfers, moving from the Java Keystore to OpenSSL is by far the easiest. Comprising just a handful of steps, you\u2019ll be done with this in no time\u2014especially with this step-by-step guide.<\/p>\n

Note: It might be easier to just create a new CSR in OpenSSL and then reissue your certificate. But this way works, too.<\/p>\n

Moving Your Java Keytool SSL Certificate to OpenSSL<\/p>\n

    \n
  1. Use the \u201cKeytool<\/strong>\u201d to generate a new private and public key pair.<\/li>\n
  2. Using the same \u201cKeytool<\/strong>,\u201d export the new self-signed certificate from PrivateKeyEntry<\/strong>.<\/li>\n
  3. Display the details of the certificate using the \u201cKeytool<\/strong>.\u201d<\/li>\n
  4. Use \u201cOpenSSL<\/strong>\u201d to view the recently exported certificate.<\/li>\n
  5. Enter \u201cDumpKey.java\u201d<\/strong> to remove the key pair from the \u201cKeytool<\/strong>\u201d keystore.<\/li>\n
  6. Use \u201cOpenSSL<\/strong>\u201d to convert the dumped key pair to Base64<\/strong>.<\/li>\n
  7. Use \u201cOpenSSL<\/strong>\u201d to view the key pair and the converted keystore files<\/strong>.<\/li>\n<\/ol>\n
