openssl interview questions
Top openssl frequently asked interview questions
Hi I don't really understand this one:
according to: http://www.madboa.com/geek/openssl/#key-rsa , You can generate a public key from a private key.
openssl genrsa -out mykey.pem 1024
openssl rsa -in mykey.pem -pubout > mykey.pub
My initial thinking was that they are generated in a pair together.
Does RSA private key contain the sum? or the public key?

when running a Rails server, I get the following error:
no such file to load -- openssl
I try a solution I find online. I go to ~/.rvm/src/ruby-1.9.2-head/ext/openssl. I type : ruby extconf.rb, but I get the following:
=== OpenSSL for Ruby configurator ===
=== Checking for system dependent stuff... ===
checking for t_open() in -lnsl... no
checking for socket() in -lsocket... no
checking for assert.h... yes
=== Checking for required stuff... ===
checking for openssl/ssl.h... no
=== Checking for required stuff failed. ===
Makefile wasn't created. Fix the errors above.
I cannot use make nor make install.

I'm generating a self-signed SSL certificate to protect my server's admin section, and I keep getting this message from OpenSSL:
unable to write 'random state'
What does this mean? A quick Google search yields nothing useful, so I thought I'd try out the new Stack Overflow!
This is on an Ubuntu server. I have upgraded libssl to fix the recent security vulnerability.
Source: (StackOverflow)
I'm adding https support to an embedded linux device. I have tried to generate a self-signed certificate with these steps:
openssl req -new > cert.csr
openssl rsa -in privkey.pem -out key.pem
openssl x509 -in cert.csr -out cert.pem -req -signkey key.pem -days 1001
cat key.pem>>cert.pem
This works, but I get some errors with, for example, google chrome:
This is probably not the site you are looking for!
The site's security certificate is not trusted!
Am I missing something? Is this the correct way to build a self-signed certificate?

PEM_read_bio_PrivateKey()
returns NULL
if a private key is encrypted by DES EDE in ECB mode. The issue happens in EVP_DecryptFinal_ex()
:
4128:error:06065064:digital envelope routines:EVP_DecryptFinal_ex:bad decrypt:evp_enc.c:330:
If the same private key is encrypted by DES EDE in CBC mode, this function works OK.
I checked, this issue is reproducible on openssl 0.9.8r/y versions (without FIPS). If openssl is built with FIPS the issue doesn't happen.
What causes this behaviour?
Thanks!

"OpenSSL 1.01 — the one production version affected — had been
shipping since March 12, 2012"
Does this (above) mean that a Windows 2012 R2 server we ordered a month ago, now running HTTPS sites in IIS, is vulnerable to Heartbleed attacks?
I've read a post that suggests checking if your server is vulnerable, by using this site http://filippo.io/Heartbleed/ , but it's probably taking a ton of hits right now, as it's not responding.

I tried to implement a protocol that can run TLS over TLS using twisted.protocols.tls
, an interface to OpenSSL using a memory BIO.
I implemented this as a protocol wrapper that mostly looks like a regular TCP transport, but which has startTLS
and stopTLS
methods for adding and removing a layer of TLS respectively. This works fine for the first layer of TLS. It also works fine if I run it over a "native" Twisted TLS transport. However, if I try to add a second TLS layer using the startTLS
method provided by this wrapper, there's immediately a handshake error and the connection ends up in some unknown unusable state.
The wrapper and the two helpers that let it work looks like this:
from twisted.python.components import proxyForInterface
from twisted.internet.error import ConnectionDone
from twisted.internet.interfaces import ITCPTransport, IProtocol
from twisted.protocols.tls import TLSMemoryBIOFactory, TLSMemoryBIOProtocol
from twisted.protocols.policies import ProtocolWrapper, WrappingFactory
class TransportWithoutDisconnection(proxyForInterface(ITCPTransport)):
"""
A proxy for a normal transport that disables actually closing the connection.
This is necessary so that when TLSMemoryBIOProtocol notices the SSL EOF it
doesn't actually close the underlying connection.
All methods except loseConnection are proxied directly to the real transport.
"""
def loseConnection(self):
pass
class ProtocolWithoutConnectionLost(proxyForInterface(IProtocol)):
"""
A proxy for a normal protocol which captures clean connection shutdown
notification and sends it to the TLS stacking code instead of the protocol.
When TLS is shutdown cleanly, this notification will arrive. Instead of telling
the protocol that the entire connection is gone, the notification is used to
unstack the TLS code in OnionProtocol and hidden from the wrapped protocol. Any
other kind of connection shutdown (SSL handshake error, network hiccups, etc) are
treated as real problems and propagated to the wrapped protocol.
"""
def connectionLost(self, reason):
if reason.check(ConnectionDone):
self.onion._stopped()
else:
super(ProtocolWithoutConnectionLost, self).connectionLost(reason)
class OnionProtocol(ProtocolWrapper):
"""
OnionProtocol is both a transport and a protocol. As a protocol, it can run over
any other ITransport. As a transport, it implements stackable TLS. That is,
whatever application traffic is generated by the protocol running on top of
OnionProtocol can be encapsulated in a TLS conversation. Or, that TLS conversation
can be encapsulated in another TLS conversation. Or **that** TLS conversation can
be encapsulated in yet *another* TLS conversation.
Each layer of TLS can use different connection parameters, such as keys, ciphers,
certificate requirements, etc. At the remote end of this connection, each has to
be decrypted separately, starting at the outermost and working in. OnionProtocol
can do this itself, of course, just as it can encrypt each layer starting with the
innermost.
"""
def makeConnection(self, transport):
self._tlsStack = []
ProtocolWrapper.makeConnection(self, transport)
def startTLS(self, contextFactory, client, bytes=None):
"""
Add a layer of TLS, with SSL parameters defined by the given contextFactory.
If *client* is True, this side of the connection will be an SSL client.
Otherwise it will be an SSL server.
If extra bytes which may be (or almost certainly are) part of the SSL handshake
were received by the protocol running on top of OnionProtocol, they must be
passed here as the **bytes** parameter.
"""
# First, create a wrapper around the application-level protocol
# (wrappedProtocol) which can catch connectionLost and tell this OnionProtocol
# about it. This is necessary to pop from _tlsStack when the outermost TLS
# layer stops.
connLost = ProtocolWithoutConnectionLost(self.wrappedProtocol)
connLost.onion = self
# Construct a new TLS layer, delivering events and application data to the
# wrapper just created.
tlsProtocol = TLSMemoryBIOProtocol(None, connLost, False)
tlsProtocol.factory = TLSMemoryBIOFactory(contextFactory, client, None)
# Push the previous transport and protocol onto the stack so they can be
# retrieved when this new TLS layer stops.
self._tlsStack.append((self.transport, self.wrappedProtocol))
# Create a transport for the new TLS layer to talk to. This is a passthrough
# to the OnionProtocol's current transport, except for capturing loseConnection
# to avoid really closing the underlying connection.
transport = TransportWithoutDisconnection(self.transport)
# Make the new TLS layer the current protocol and transport.
self.wrappedProtocol = self.transport = tlsProtocol
# And connect the new TLS layer to the previous outermost transport.
self.transport.makeConnection(transport)
# If the application accidentally got some bytes from the TLS handshake, deliver
# them to the new TLS layer.
if bytes is not None:
self.wrappedProtocol.dataReceived(bytes)
def stopTLS(self):
"""
Remove a layer of TLS.
"""
# Just tell the current TLS layer to shut down. When it has done so, we'll get
# notification in *_stopped*.
self.transport.loseConnection()
def _stopped(self):
# A TLS layer has completely shut down. Throw it away and move back to the
# TLS layer it was wrapping (or possibly back to the original non-TLS
# transport).
self.transport, self.wrappedProtocol = self._tlsStack.pop()
I have simple client and server programs for exercising this, available from launchpad (bzr branch lp:~exarkun/+junk/onion
). When I use it to call the startTLS
method above twice, with no intervening call to stopTLS
, this OpenSSL error comes up:
OpenSSL.SSL.Error: [('SSL routines', 'SSL23_GET_SERVER_HELLO', 'unknown protocol')]
Why do things go wrong?

Mac OS X already provides this software and installing another version in
parallel can cause all kinds of trouble.
The OpenSSL provided by OS X is too old for some software.
Generally there are no consequences of this for you. If you build your

The problem is in the question. I've done a thorough investigation for solutions in regards to this and I know there are topics to this and I've followed them too and nothing has worked. That being said I'll list out exactly everything I've done so far. I am running PHP 5.2.14 with Zend Debugging on the latest Eclipse version on my Windows XP computer. I have a 1 GB of RAM. I have XAMPP running with Apache, MySQL, and FileZilla installed.
On XAMPP I've done the following (Apache was off during these changes):
Clicked on Admin from the XAMPP Control Panel and went to https:// localhost/xampp/
. From there I accepted the certs from this line on the welcome page:
For OpenSSL support please use the test certificate with https:// 127.0.0.1 or https:// localhost.
On that same section I checked phpinfo()
. Under 'Environment', SERVER["HTTPS"]
is on
. Under 'Apache Environment', HTTPS
is On
. Under 'PHP Variables, _SERVER["HTTPS"]
is On
. Under 'Phar', OpenSSL support
is disabled
(install ext/openssl). I don't know how to enable the Phar one.
Now regarding the files themselves in C:\xampp, I went to the PHP folder. Under both production and development php.ini files (better safe than sorry), I have allow_url_fopen=On
, allow_url_include=On
, and I removed the semicolon, so that extension=php_openssl.dll
is no longer commented out. I even confirmed that the .dll is in the ext folder of the PHP folder. Both libeay32.dll and ssleay32.dll are in the PHP and Apache folders. The Apache folder doesn't contain either productive or development php.ini files.
I've went to http://www.slproweb.com/products/Win32OpenSSL.html and installed Win32 OpenSSL v1.0.0d for safe measure.
Now the line of code in question in my retrieve_website.php looks like this:
$urlquery = "https://www.googleapis.com/customsearch/v1?key=".$appid."&cx=".$google_searchid."&q=".$query."&alt=atom&num=".$results;
$xmlresults = file_get_contents($urlquery);
I have two other websites that I query but they are served via HTTP and they work fine. I also have this line of code entered near the end of the script:
echo 'openssl: ', extension_loaded ('openssl') ? 'yes':'no', "\n";
echo 'http wrapper: ', in_array('http', $w) ? 'yes':'no', "\n";
echo 'https wrapper: ', in_array('https', $w) ? 'yes':'no', "\n";
echo 'wrappers: ', var_dump($w);
When I run it as a PHP Script on Eclipse, everything outputs perfectly fine the way I want along with these results:
openssl: yes
http wrapper: yes
https wrapper: yes
wrappers: array(10) {
[0]=>
string(5) "https"
[1]=>
string(4) "ftps"
[2]=>
string(3) "php"
[3]=>
string(4) "file"
[4]=>
string(4) "data"
[5]=>
string(4) "http"
[6]=>
string(3) "ftp"
[7]=>
string(13) "compress.zlib"
[8]=>
string(14) "compress.bzip2"
[9]=>
string(3) "zip"
}
Despite all these changes I've made (after I started up Apache), I still get the same errors the first time I access my PHP script in Eclipse and Firefox via http://localhost/tutorial/retrieve_website.php:
Warning: file_get_contents() [function.file-get-contents]: Unable to find the wrapper "https" - did you forget to enable it when you configured PHP? in C:\xampp\htdocs\tutorial\retrieve_website.php on line 29

What is it that I have overlooked or failed to do? To my own knowledge, I've done everything that I've researched about concerning HTTPS and OpenSSL

I am trying to convert from a Java keystore file into a PEM file using keytool and openssl applicactions. But I could not find a good way to do the conversion. Any ideas?
Instead of converting the keystore directly into PEM I tried to create a PKCS12 file first and then convert into relevant PEM file and Keystore. But I could not establish a connection using them. (Note that I just need a PEM file and a Keystore file to implement a secured connection. There is no restriction like "Start from a java keystore file". :) So starting from other formats is acceptable with my case)
But a direct conversion method from jks to pem is preferable.
