class common.net.ds.aes.AESModeOfOperationCTR(key, counter=None)

Bases: common.net.ds.aes.AESStreamModeOfOperation

AES Counter Mode of Operation.

o A stream-cipher, so input does not need to be padded to blocks,
allowing arbitrary length data.

o The counter must be the same size as the key size (ie. len(key)) o Each block independant of the other, so a corrupt byte will not

damage future blocks.
o Each block has a uniue counter value associated with it, which
contributes to the encrypted value, so no data patterns are leaked.
o Also known as: Counter Mode (CM), Integer Counter Mode (ICM) and
Segmented Integer Counter (SIC
Security Notes:

o This method (and CBC) ARE recommended. o Each message block is associated with a counter value which must be

unique for ALL messages with the same key. Otherwise security may be compromised.

locatelocal locates a file, i.e. returns the url of the server where the specified file resides. Only the local dataservers are probed.

path = name of the file

locateremote(path)

locateremote locates a file, i.e. returns the url of the server where the specified file resides. Only remote dataservers are probed.

path = name of the file

md5sum(path, host=None, port=None)

md5sum calculates the md5 check sum of a file. The file must exist on the contacted server, the path must be returned from a locate call.

path = name of the file as returned by locate. host = optional host name where the file resides. port = optional port number of the server where the file resides.

mirrorput(path, port=8000, directory='')

mirrorput make the data server retrieve file path to its sdata directory

path = path to local file port = port local ds listens on directory = change the directory where the file should be mirrored

myprint(level, text)
ping()

See if there is a server running out there and get the server info.

put(path)

put stores a file on a local dataserver

path = path to local file

register(path, validation)

register gets a dataserver to register a file which is already in one of the dataserver directories.

path = path to the file (w.r.t. the working directory)

release(validation)

release gets a dataserver to release the port the server is listening on

reload(validation, force=False)

reload lets a dataserver rescan the directory structure

force = True forces, False doesn’t

restart(defaultkey, host=None, port=None, gpghomedir=None)
sha1sum(path, host=None, port=None)

md5sum calculates the sha1 check sum of a file. The file must exist on the contacted server, the path must be returned from a locate call.

path = name of the file as returned by locate. host = optional host name where the file resides. port = optional port number of the server where the file resides.

size(path, host=None, port=None)

size calculates the size of a file. The file must exist on the contacted server, the path must be returned from a locate call.

path = name of the file as returned by locate. host = optional host name where the file resides. port = optional port number of the server where the file resides.

stat(path, host=None, port=None)

stat returns the stat tuple a file. The file must exist on the contacted server, the path must be returned from a locate call.

path = name of the file as returned by locate. host = optional host name where the file resides. port = optional port number of the server where the file resides.

takeover(validation, newport, certfile='')

takeover gets a dataserver to take over the port the current server is listening on

testcache()

testcache tests whether the server is allowed to cache files

testfile(path)

testfile tests whether a file exists on the server

path = name of the file

teststore()

teststore tests whether the server is allowed to store files
