  • How do I remove a passphrase from a key?

     

     

     

      

    Perhaps you’ve grown tired of typing your passphrase every time your secure daemon starts. You can decrypt your key,  removing the passphrase requirement, using the rsa or dsa option,  depending on the signature algorithm you chose when creating your private key.

      

    If you created an RSA key and it is stored in a standalone file called key.pem, then  here’s how to output a decrypted version of the same key to a file called newkey.pem.

     

    # you'll be prompted for your passphrase one last time openssl rsa -in key.pem -out newkey.pem 

      

    Often, you’ll have your private key and public certificate stored in the same file. If they are stored in a file called  mycert.pem, you can construct a decrypted version called newcert.pem in two steps.

     

    # you'll need to type your passphrase once more openssl rsa -in mycert.pem -out newcert.pem openssl x509 -in mycert.pem >>newcert.pem

  • Using this command-line invocation, you’ll have to answer a lot of questions: Country Name, State, City, and so on. The  tricky question is “Common Name.” You’ll want to answer with the  hostname or CNAME by which people will address the server. This is very important.  If your web server’s real hostname is mybox.mydomain.com but people will be using  www.mydomain.com to address the box, then use the latter name to answer the “Common Name” question.
