hi all, i run into this problem “
”The debugged program raised the exception unhandled Error
"[('PEM routines', 'PEM_read_bio', 'no start line'), ('SSL routines',
'SSL_CTX_use_PrivateKey_file', 'PEM lib')]"
File:
/usr/lib/python2.5/site-packages/Twisted-10.0.0-py2.5-linux-i686.egg/twisted/internet/ssl.py,
Line: 99"
(
usr/lib/python25/site-packages/Twisted-10.0.0-py2.5-linux-i686.egg/twisted/internet/ssl.py
line 99 )
def cacheContext(self):
if self._context is None:
ctx = self._contextFactory(self.sslmethod)
# Disallow SSLv2! It's insecure! SSLv3 has been around since
# 1996. It's time to move on.
ctx.set_options(SSL.OP_NO_SSLv2)
ctx.use_certificate_file(self.certificateFileName)
ctx.use_privatekey_file(self.privateKeyFileName) # Line: 99
self._context = ctx
here is the way i create privkey file :
$ openssl genrsa > privkey.pem
then
$ openssl req -new -x509 -key privkey.pem -out cacert.pem -days 1000
i have checked the cacert.pem file it do has 'strt line ' －－BEGIN
CERTIFICATE－－－－
part of my code :
class syslogOptions(usage.Options):
optParameters = [['cert', 'c', '/home/ssltest/cacert.pem','SSL Server
certificate'],
['ip', 'i', None, 'IP Address to listen on']]
def postOptions(self):
if (not self.opts['cert']) or (not
os.path.isfile(self.opts['cert'])):
raise usage.UsageError, "%s: is not a file" % self.opts['cert']
. . .
syslogSSL = syslogFactory()
syslogSSL.protocol = outputTCP
ctx = ssl.DefaultOpenSSLContextFactory(config.opts['cert'],
config.opts['cert'])
.. .. .
reactor.listenSSL(708, syslogSSL , ctx, interface=config.opts['ip'])
reactor.run()
any ideas ? ...
