Read the following

A simple connection

import socket
from org.keyphrene import SSH2
# or 
# from ssh4py import SSH2
 
 
HOSTNAME = "127.0.0.1"
PORT = 22
LOGIN = "login"
PWD = "password"
 
 
# A simple connection
 
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sock.connect((HOSTNAME, PORT))
sock.setblocking(1)
 
ssh = SSH2.Session()
ssh.setBanner(SSH2.DEFAULT_BANNER+" Python (http://www.keyphrene.com/projects/org.keyphrene)")
ssh.startup(sock)
ssh.setPassword(LOGIN, PWD)
 
# here, your operations
 
# Execute
channel = ssh.Channel()
channel.execute("echo test")
while 1:
 data = channel.read(1024)
 if not data: break
 print data
channel.close()
 
# Open a terminal
channel = ssh.Channel()
channel.pty("xterm", "", 0, 80, 24)
channel.shell()
channel.setBlocking(1)
# ...
channel.close()
 
ssh.close()

How to get the DNS server list

from org.keyphrene import winnet
 
print winnet.getNetworkParams()

Result:

{'DnsServerList': '127.0.0.1', 'Domain': 'keyphrene.com', 'Hostname': 'your-XXXXXX'}

Digest

from org.keyphrene.crypto import Digest, HMAC
 
########
# SHA 1
d = Digest("sha1")
print "SHA1 Size: %d" % d.get_size()
d.update("naja")
print "SHA1: %s" % d.digest()
 
 
########
# MD5 1
d = Digest("md5")
print "MD5 Size: %d" % d.get_size()
d.update("naja")
print "MD5: %s" % d.digest()

List of Digests: sha, sha1, md5, md4, md2, mdc2, rmd160

HMAC

from org.keyphrene.crypto import Digest, HMAC
 
key = "a key"
digestmod = "md5"
hmac = HMAC(key, digestmod)
hmac.update("your data")
print hmac.final()

List of digestmod: md5, sha, sha1

Calculate the cyclic redundancy ...

from org.keyphrene import crc64
 
print crc64.string("your data")

Hunspell is a spell checker.

from org.keyphrene import hunspell
 
spell = hunspell.Hunspell("./fr_FR.aff","./fr_FR.dic")
word = "copi"
print spell.spell(word)
