dragon-e 2.0.1

Encrypt like a dragon: new method for securing data

Dragon-E

What is it?

Dragon-E (or just Dragon) is a simple but powerful library to encode messages. It relies on the end-user having the decryption key.

What does it look like?

Encoded messages will look something like this: 154:221:169:238:253:184:108:204:179:230:206:254:185:220:241:251:179:135:226:169:116:183:139:180:240:245:178:192:254:170:236:195:237:189:148:168:241:166:218:242:86:200:197:139:189:250:243:106:188:232:168:238:189:236:174:150 In this case, the original message was Dragon Encryption is a lightweight, easy to use package. and was encoded using the passkey AV3ry57r0nGp4Ssw0Rd!?.

What makes it so amazing?

1. Unlike some other encryption methods, the encoded message's length is not dependent on the passkey's length. This makes it more difficult to guess the passcode.
2. Every part of the passkey is important, meaning that you can't solve it all at once.
3. The longer the message and passkey, the more difficult it is to decode.
4. As of its 2.0.0 update, Dragon offers Image Encryption! This essentially encrypts the message using stealthencrypt and then transfers it into an image.
   • The resulting image is of type PIL.Image and is always square.

How can I download it?

pip install dragon-e

EXAMPLE

Encrypting

import dragon_e as de

important_info = de.encrypt("Don't share this info with anybody!", "V3ry57r0ngS3cuR17yK3Y")
with open('secret_file.dragon', 'w') as f:
    f.write(important_info)

import dragon_e as de

important_info = de.stealthencrypt("Don't share this info with anybody!", "V3ry57r0ngS3cuR17yK3Y")
# Stealth Encryption just removes the delimiters and can be decoded the exact same way as with delimiters.
with open('secret_file.dragon', 'w') as f:
    f.write(important_info)

import dragon_e as de

im = de.imageencrypt("Don't share this info with anybody!", "V3ry57r0ngS3cuR17yK3Y")
im.show()

The above code would display this image: which could be decrypted with imagedecrypt.

Decrypting

import dragon_e as de
f = open('secret_file.dragon', 'r')
super_secret = f.read()
f.close()
decrypted = de.decrypt(super_secret, "V3ry57r0ngS3cuR17yK3Y")
print("Decoded information: "+decrypted)

import dragon_e as de
decrypted = de.imagedecrypt("path/to/image.png", "V3ry57r0ngS3cuR17yK3Y")
print("Decoded information: "+decrypted)
