Learn to crack the Affine Cipher in Python with this step-by-step guide. Explore classical cryptography, understand modular arithmetic and linear algebra in encryption, and master brute force decryption with practical Python code.
Encryption works by scrambling data using an algorithm known as an "encoder" that transforms plaintext into ciphertext (a series of random characters). To decode the ciphertext again requires a "decoder", which takes this encrypted message back into readable text form using another algorithm with...

Add a shift to this index to determine the index of the cipher character to use. Use % 26 to make sure the shift will wrap back to the start of the alphabet. Append the cipher character to the result string. After the loop finishes iterating over the text value, the result is returne...

I like to know how to generate private and public keys in pem file extension from pfx files using command in win2012.The reason is my application installed on my win2012 server accept pem files only and does not accept pfx files. TIA!
I think it can also be a good complement to official documentations. I did my best to make this handbook a single and consistent. Is organized in an order that makes logical sense to me. Of course, I still have a lot to improve and to do. I hope you enjoy it, and fun with it....
