note 93946 added to book.openssl

OpenSSL creates asynchronous key pairs, however I wanted to have the private key something that was human-memorizable. With the standard keys generated, this is not possible. How I achieved it was to use two types of encryption. After generating a key pair with OpenSSL, the public key can be stored in plain text format. I then encrypted the private key itself using regular mcrypt with the human-memorizable key of my choice and converted it to ACSII using urlencode(). Then to get the private key back, I just decrypted it with mcrypt. This way I could store the encrypted private key on the server without worrying about having things stored unencrypted. Of course, this will only be as good as your human-memorizable key is and can potentially reduce the security of your script if you choose something simple or don't use salts. ---- Server IP: 92.48.74.199 Probable Submitter: 190.241.39.11 ---- Manual Page -- http://www.php.net/manual/en/book.openssl.php Edit -- https://master.php.net/note/edit/93946 Del: integrated -- https://master.php.net/note/delete/93946/integrated Del: useless -- https://master.php.net/note/delete/93946/useless Del: bad code -- https://master.php.net/note/delete/93946/bad+code Del: spam -- https://master.php.net/note/delete/93946/spam Del: non-english -- https://master.php.net/note/delete/93946/non-english Del: in docs -- https://master.php.net/note/delete/93946/in+docs Del: other reasons-- https://master.php.net/note/delete/93946 Reject -- https://master.php.net/note/reject/93946 Search -- https://master.php.net/manage/user-notes.php
