RSA-Calculator with tkinter GUI in python. RSA is the algorithm used by modern computers to encrypt and decrypt messages. It is an asymmetric cryptographic algorithm. Asymmetric means that there are two different keys. This is also called public key cryptography, because one of them can be given to everyone. The other key must be kept private. Encrypted message can be decrypted only by private key known only by Receiver. Receiver use the private key to decrypt message to get Plain Text. Step 1 Set p and q. Choose p and q as prime numbers. Step 2 Choose public key e (Encryption Key) Choose e from below values. RSA encryption, decryption and prime calculator. This is a little tool I wrote a little while ago during a course that explained how RSA works. The course wasn't just theoretical, but we also needed to decrypt simple RSA messages. Given that I don't like repetitive tasks, my decision to automate the decryption was quickly made. Affine decryption requires to know the two keys A and B (the one from encryption) and the used alphabet. Example: Decrypt the ciphered message SNVSX with keys A=5 and B=3 For each letter of the alphabet corresponds the value of its position in the alphabet.

Encryption uses a classic alphabet, and two integers, called coefficients or keys A and B, these are the parameters of the affine function Ax+B. Kmspico office 2019 mydigitallife.

Example: Encrypt DCODE with the keys A=5, B=3 and the English/latin alphabet ABCDEFGHIJKLMNOPQRSTUVWXYZ.

For each letter of the alphabet is associated to the value of its position in the alphabet (starting at 0).

Example: By default, A=0, B=1,.., Z=25, but it is possible (but not recommended) to use A=1, .., Y=25, Z=0 using the alphabet ZABCDEFGHIJKLMNOPQRSTUVWXY.

For each letter of value $ x $ of the plain text, is associated a value $ y $, resulting of the affine function $ y = A times x + B mod 26 $ (with $ 26 $ the alphabet size). For each value $ y $, corresponds a letter with the same position in the alphabet, it is the ciphered letter. The Affine ciphertext is the replacement of all the letters by the new ones.
