An appropriate **length** value will be calculated based on the requested entropy amount, and the size of the character set. This can be a positive integer, or one of the following preset strings: ``"weak"`` (24), ``"fair"`` (36), ``"strong"`` (48), and ``"secure"`` (56). If neither this or **length** is specified, **entropy** will default to ``"strong"`` (48). :param length: Size of resulting password, measured in characters. If omitted, the size is auto-calculated based on the **entropy** parameter. If both **entropy** and **length** are specified, the stronger value will be used. :param returns: Controls what this function returns: * If ``None`` (the default), this function will generate a single password. * If an integer, this function will return a list containing that many passwords. * If the ``iter`` constant, will return an iterator that yields passwords. :param chars: Optionally specify custom string of characters to use when randomly generating a password. This option cannot be combined with **charset**. :param charset: The predefined character set to draw from (if not specified by **chars**). There are currently four presets available: * ``"ascii_62"`` (the default) -- all digits and ascii upper & lowercase letters. Provides ~5.95 entropy per character. * ``"ascii_50"`` -- subset which excludes visually similar characters (``1IiLl0Oo5S8B``). Provides ~5.64 entropy per character. * ``"ascii_72"`` -- all digits and ascii upper & lowercase letters, as well as some punctuation. Provides ~6.17 entropy per character. * ``"hex"`` -- Lower case hexadecimal. Providers 4 bits of entropy per character. :returns: :class:`!unicode` string containing randomly generated password; or list of 1+ passwords if :samp:`returns={int}` is specified. )rtrzrn)rrzrtrr{gens r*rrs#L  ?vw ?$ ?C w<r,ct|d5}d|D}td|D}dddtjdt ||S#1swY+xYw)a2 load wordset from compressed datafile within package data. file should be utf-8 encoded :param asset_path: string containing absolute path to wordset file, or "python.module:relative/file/path". :returns: tuple of words, as loaded from specified words file. zutf-8c3<K|]}|jywrU)striprXs r*r3z _load_wordset..s+tzz|sc3&K|] }|s| ywrUrnrXs r*r3z _load_wordset..s3stddssNz!loaded %d-element wordset from %r)rCtupler debugr4) asset_pathfhrwordss r* _load_wordsetrsT *g ."++3s33 /$II13u:zJ L' / .s AAcdeZdZdZdZdZfdZdZdZdZ dZ e dZ d Z d Zd ZxZS) WordsetDictz Special mapping used to store dictionary of wordsets.

This function uses :mod:`random.SystemRandom` to generate one or more passwords; it can be configured to generate alphanumeric passwords, or full english phrases. The complexity of the password can be specified by size, or by the desired amount of entropy. Usage Example:: >>> # generate random phrase with 48 bits of entropy >>> from passlib import pwd >>> pwd.genphrase() 'gangly robbing salt shove' >>> # generate a random phrase with 52 bits of entropy >>> # using a particular wordset >>> pwd.genword(entropy=52, wordset="bip39") 'wheat dilemma reward rescue diary' :param entropy: Strength of resulting password, measured in 'guessing entropy' bits. An appropriate **length** value will be calculated based on the requested entropy amount, and the size of the word set. This can be a positive integer, or one of the following preset strings: ``"weak"`` (24), ``"fair"`` (36), ``"strong"`` (48), and ``"secure"`` (56). If neither this or **length** is specified, **entropy** will default to ``"strong"`` (48). :param length: Length of resulting password, measured in words. If omitted, the size is auto-calculated based on the **entropy** parameter. If both **entropy** and **length** are specified, the stronger value will be used. :param returns: Controls what this function returns: * If ``None`` (the default), this function will generate a single password. * If an integer, this function will return a list containing that many passwords. * If the ``iter`` builtin, will return an iterator that yields passwords. :param words: Optionally specifies a list/set of words to use when randomly generating a passphrase. This option cannot be combined with **wordset**. :param wordset: The predefined word set to draw from (if not specified by **words**). There are currently four presets available: ``"eff_long"`` (the default) Wordset containing 7776 english words of ~7 letters. Constructed by the EFF, it offers ~12.9 bits of entropy per word. This wordset (and the other ``"eff_"`` wordsets) were `created by the EFF `_ to aid in generating passwords. See their announcement page for more details about the design & properties of these wordsets. ``"eff_short"`` Wordset containing 1296 english words of ~4.5 letters. Constructed by the EFF, it offers ~10.3 bits of entropy per word. ``"eff_prefixed"`` Wordset containing 1296 english words of ~8 letters, selected so that they each have a unique 3-character prefix. Constructed by the EFF, it offers ~10.3 bits of entropy per word. ``"bip39"`` Wordset of 2048 english words of ~5 letters, selected so that they each have a unique 4-character prefix. Published as part of Bitcoin's `BIP 39 `_, this wordset has exactly 11 bits of entropy per word. This list offers words that are typically shorter than ``"eff_long"`` (at the cost of slightly less entropy); and much shorter than ``"eff_prefixed"`` (at the cost of a longer unique prefix). :param sep: Optional separator to use when joining words. Defaults to ``" "`` (a space), but can be an empty string, a hyphen, etc. :returns: :class:`!unicode` string containing randomly generated passphrase; or list of 1+ passphrases if :samp:`returns={int}` is specified. )rzrtrn)rrs r*rrs#B  A'& AD AC w<r,rU)r9r)=r __future__rrrrrA collectionsrcollections.abcr ImportErrormathr r r0logging getLoggerrrJrDpasslibr passlib.utils.compatr r rr passlib.utilsrrrpasslib.utils.decorr__all__dictrqr+r=rClistrrr^ frozensetr]r[rjrurlrrrrrrsplitnamerrrrnr,r*rsm0SR #+.#'g''1 CC551      *" !RX;.-9  u)(\I#I#h WNB  $E=%E=XGZ F98.98|= 4 9 9 ;Dd$Cd$JK < K$'K$dbM+*+sD DD
