__doc__ = """hashlib module - A common interface to many hash functions.
new(name, data=b'', **kwargs) - returns a new hash object implementing the
given hash function; initializing the hash
using the given binary data.
Named constructor functions are also available, these are faster
than using new(name):
md5(), sha1(), sha224(), sha256(), sha384(), sha512(), blake2b(), blake2s(),
sha3_224, sha3_256, sha3_384, sha3_512, shake_128, and shake_256.
More algorithms may be available on your platform but the above are guaranteed
to exist. See the algorithms_guaranteed and algorithms_available attributes
to find out what algorithm names can be passed to new().
NOTE: If you want the adler32 or crc32 hash functions they are available in
the zlib module.
Choose your hash function wisely. Some have known collision weaknesses.
sha384 and sha512 will be slow on 32 bit platforms.
Hash objects have these methods:
- update(data): Update the hash object with the bytes in data. Repeated calls
are equivalent to a single call with the concatenation of all
the arguments.
- digest(): Return the digest of the bytes passed to the update() method
so far as a bytes object.
- hexdigest(): Like digest() except the digest is returned as a string
of double length, containing only hexadecimal digits.
- copy(): Return a copy (clone) of the hash object. This can be used to
efficiently compute the digests of datas that share a common
initial substring.
For example, to obtain the digest of the byte string 'Nobody inspects the
spammish repetition':
>>> import hashlib
>>> m = hashlib.md5()
>>> m.update(b"Nobody inspects")
>>> m.update(b" the spammish repetition")
>>> m.digest()
b'\\xbbd\\x9c\\x83\\xdd\\x1e\\xa5\\xc9\\xd9\\xde\\xc9\\xa1\\x8d\\xf0\\xff\\xe9'
More condensed:
>>> hashlib.sha224(b"Nobody inspects the spammish repetition").hexdigest()
'a4337bc45a8fc544c03f52dc550cd6e1e87021bc896588bd79e901e2'

Em is a novice freelance model based in Vancouver, BC. She adores pin-up aestethic and loves anything 40s and 50s inspired.
Full Bio
Hello my lovely darlings! I'm Em, a novice freelance model based out of Vancouver in the beautiful province of British Columbia, Canada. I absolutely love Pin-Up style: the over-the-top expressions, the dresses, the vintage lingerie, the make-up, the curls. I adore it all! I am especially over the moon about anything 40s and 50s inspired - think tea length swing dresses, circle skirts, and polkadots! I also enjoy me a good wiggle dress, of course!
I would love to get to shoot more pin-up looks! If you're interested in working together, please let me know a little bit about yourself 🙂
Published PNW Redheaded Pin Up. An officially sweatered member of the Capital City Dolls. Active in promoting Equality, Equity, Body Positivity, Inclusivity, Mental Health, Community Outreach, and Vintage Style Not Vintage Values.
Over 40 and fabulous! Lover of all things vintage, retro, and mid century. Music is definitely a life force. Dreams don’t have an expiration date, so chase them!
I began my photographic love in 1975. I was first published in high school and didn't save the negatives or the prints as I thought it was something that happened to everyone. i
A lover of all things glam. About a year and a half ago I was introduced to this incredible world through my hair and makeup craft. With over 12 years in the beauty industry, I’ve worked with multiple designers, celebrities, and my work has been published both internationally and domestic, In addition I have a bridal team in multiple cities. My story with Pinup started when I partnered with Glitter Glam Studios for a session and we quickly became her official hair and makeup team. It’s been an incredible journey, with multiple magazine spreads and cover, fulfilling a dream to become a model. Fully immersed, I now have a Retro hair and makeup team with goals to keep expanding and become the go to glam at all pinup events, we have had the honor to work with published pinups and our work can be seen in Retro Lovely, Modern Day PinUp, Bombshell, Holidays, NYLON, and so much more.
After 10 years of doing hair and make up on the pinup scene, Lucky dove in victory rolls first into competing. Ms. Lucky is the vivacious recruiter for the Oklahoma Battlin’ Betties Platoon. Lucky is a true bombshell both on and off the stage. When she's not shaping and molding young minds, she's indulging in her love for tacos and savoring her precious days off. She loathes working and doing dishes! Lucky is a two time national pageant title holder and has a flair for the dramatic and a heart full of passion
Hey doll! My name is Lucious Lady Libra. I’m originally from New York but am now living in sunny Orlando! I have a passion for all things old Hollywood and classic glamour. I love tattoos and astrology and am very excited to be starting this pinup adventure!
