The purr-fect way to keep your secrets fur-ever safe, straight from the meow-th of your computer to your fur-ends' paws!
Important
PurrCrypt is real cryptography in a fuzzy disguise! Your messages are protected by the same elliptic curve algorithms used by Bitcoin, just wrapped in adorable cat and dog sounds. Cuteness should never compromise security!
PurrCrypt is what happens when a very serious cryptographer gets distracted by cat videos for 48 hours straight! It's a super-strong encryption tool that hides your secrets in the most adorable way possible - by turning them into kitty and puppy speak!
Under the fluffy exterior, PurrCrypt uses the same elliptic curve cryptography (meow-thematics?) as Bitcoin. But instead of boring code, your secret messages look like they were written by a cat walking across your keyboard... ON PURPOSE! 😸
"Finally, my keyboard stomping has been recognized as a valid form of communication!" - Your Cat, probably
Note
While PurrCrypt messages look like nonsensical pet sounds, they contain cryptographically secure data that can only be decrypted with the proper keys. No amount of treats will convince these pets to reveal your secrets!
# Clone this ball of yarn
git clone https://github.com/vxfemboy/purrcrypt.git
# Pounce into the directory
cd purrcrypt
# Install it like you'd install a new cat tree
cargo install --path .Tip
For the best experience, try saying "meow" or "woof" out loud while your encryption runs. It doesn't affect the algorithm at all, but it does make you feel more connected to the process! 🐱
-
Generate a keypair (AKA make your secret paw print):
purr genkey fluffy
This is like getting your pet microchipped, but for your messages!
-
Import your friend's key (teaching your pet who's friendly):
purr import-key --public ~/Downloads/mr_whiskers_key.pubNow your computer knows which furry friends to trust!
-
List your keys (checking who's in your pack/clowder):
purr list-keys
It's like looking at your pet's contact list, if pets had phones!
-
Choose your pet personality:
purr set-dialect cat # For the feline-inclined # or purr set-dialect dog # For the canine-convinced
The eternal debate: are you a cat person or a dog person? Now your encryption can match your pet preference!
Warning
Just like real pets, your private keys need proper protection! Keep your private key files as secure as your cat keeps its favorite napping spot. If someone else gets your private key, they can read all your secret messages, and that's a cat-astrophe!
Send a secret to your furry friend:
purr encrypt --recipient mr_whiskers --input secret_catnip_stash_locations.pdf --dialect catThis creates secret_catnip_stash_locations.pdf.purr that looks like it was written by a cat with a very specific meowing pattern!
"This message not suspicious at all. Just normal cat talk. No secrets. Meow." - Undercover Agent Whiskers
Caution
Even with cat/dog encoding, don't put your encryption keys on your collar tag! PurrCrypt is designed to hide the fact you're sending encrypted data, but once someone knows you're using it, they'll recognize those suspiciously well-structured "meows" and "woofs" for what they really are!
When your fuzzy buddy sends you a secret:
purr decrypt --key fluffy --input suspicious_dog_noises.purr --output true_meaning_of_bork.txtpurr - Because "woof" and "meow" are actually secret codes!
Usage:
purr [COMMAND] [OPTIONS]
Commands:
genkey [name] Create your pet's digital paw print
import-key [--public] <keyfile> Add a furry friend to your trusted circle
encrypt, -e Turn your boring text into pet speak
decrypt, -d Translate pet speak back to human
list-keys, -k See all the pets in your digital neighborhood
set-dialect <cat|dog> Decide if you're team 😺 or team 🐶
verbose, -v Make it extra chatty (like a Siamese cat)
Options for encrypt:
-r, --recipient <key> Which pet friend gets the message
-o, --output <file> Where to leave this furry message
-i, --input <file> The boring human file to convert
--dialect <cat|dog> Temporary species switch
Options for decrypt:
-k, --key <key> Your pet identity
-o, --output <file> Where to put the decoded human-speak
-i, --input <file> The furry message to translate
Tip
Can't remember a command? Just think: "What would my cat/dog do?" For example, to generate a key, imagine your cat making its mark (genkey), or to encrypt a file, think of your dog hiding its favorite bone (encrypt)!
PurrCrypt operates on the scientific principle that everything is better with cats and dogs:
-
Layer 1: Serious Business 🧐
- Hardcore mathematical encryption that would make your high school math teacher proud
- The same elliptic curves used by Bitcoin (but much cuter)
- So secure even the NSA would just say "awww" and leave it alone
-
Layer 2: The Fluffy Disguise 🦮🐈
- Your already-secure data gets dressed up in a pet costume
- To anyone else, it just looks like you REALLY love your pets
- "It's not encrypted data, officer! I just really like to type 'mew purr nyaa' 800 times!"
Important
While we joke about how cute this all is, PurrCrypt uses real cryptographic principles! The secp256k1 elliptic curve provides strong security, and the steganographic encoding genuinely helps hide the fact that you're sending encrypted content. Security through adorability is still security!
When your cat runs across your keyboard, it's annoying. When PurrCrypt does it, it's encryption!
🐱 Cat Mode Vocabulary:
- "mew" (for when your cat is being subtle)
- "meow" (standard cat operations)
- "purr" (contentment encryption)
- "nya" (for the anime-loving cats)
- "mrrp" (the sound of secretly plotting world domination)
🐶 Dog Mode Dictionary:
- "woof" (basic dog communication)
- "bark" (for when emphasis is needed)
- "arf" (the covert operations bark)
- "yip" (small dog, big secrets)
- "wrf" (the confused but supportive dog sound)
"The humans think it's just me expressing my excitement for treats, but I'm actually transferring nuclear launch codes." - Classified Dog Operative
Each letter repetition in pet speak is actually encoding your bits and bytes:
-
In Cat Speak, the word
mmmeeeowwwmight mean:mmm= First 2 bits are10(binary for decimal 2)eee= Next 2 bits are10(another 2)o= Next bit is0www= Last bit is1
So that cute cat noise just encoded the binary
101001! -
In Dog Speak,
bbbaaarrkktranslates to the same value:- Those aren't just excited puppies - they're quantum-resistant encryption!
Note
The repetition patterns are carefully crafted! In Complex patterns, each character group encodes distinct bits, while in Special patterns (like meow), the count of each letter is precisely mapped to specific bit positions in the encrypted data.
mew purrrr nyaaa meoww purr nyaa meeww purrr nya meww meow purrrr
nyaa meow purr nya meow purrr nyaaa mew purr mrrp purrrr nyaa
Just looks like you let your cat write your emails!
woof bark arff yipp woooof baark arfff wooof barkkk arff woooof
barkk arff woof bark yippp wooof barkkk arfff yipp wooof barkk
Now you know what dogs are REALLY barking about all night!
Warning
If you see your actual pet typing messages like these, REMAIN CALM! Either: 1) You've discovered the first typing cat/dog (congratulations!), or 2) Your pet has been recruited by a secret animal intelligence agency. Either way, treat them with extra respect and treats.
- Fur-midable Security: The NSA would need 9 lives to crack this
- Paw-sible Deniability: "That's not encryption, I just really love typing like my pet!"
- Social Engineering: Who would suspect adorable pet sounds of being top-secret data?
- Identity Protection: Are you a sophisticated spy or just another cat person? No one knows!
- Cross-Species Compatibility: Works for both cat and dog people (finally, peace in our time)
If you insist on being all professional about this (why though?), here's how to use it as a library:
use purrcrypt::{AnimalCipher, CipherDialect, CipherMode, crypto};
// Create a keypair (much less fun than just typing 'genkey fluffybutt')
let keypair = KeyPair::new();
// Do serious encryption stuff with silly outputs
crypto::encrypt_file(
"boring_document.txt",
"much_more_interesting_meows.txt",
&recipients_key,
CipherDialect::Cat // or Dog if you're THAT kind of person
).unwrap();Tip
For even more fun in your code, use variable names like top_secret_hairball, encryption_treats, or security_scratchpost. They have absolutely no effect on functionality but make reviewing your code much more enjoyable!

Caution
PurrCrypt may cause side effects including: making adorable noises while typing, increased appreciation for your pets, sudden desires to encrypt everything, and unexplained urges to meow or bark at your computer. These symptoms are harmless and may actually improve your overall quality of life.
