How to convert an array to a list in python with tutorial, tkinter, button, overview, canvas, frame, environment set-up, first python program, etc.
currently working on an assignment that requires me to write a script that inputs a line of encrypted text and a distance value and outputs plaintext using a Caesar cipher. I've done that and it works great for lower case letters however it does not work for capital letters or symbols (...

Caesar encrypted his messages by changing the order of the alphabetical letters. In order to decrypt the message, the intended recipient would have to substitute the written letter for the corresponding letter in the original message to decode the encrypted message. This is called a substitution ci...
Then we have to make sure the email link includesid="contact"in the markup, like this: <aid="contact"href="">Send me an Email</a> We are using theatobmethod to decode a string of Base64-encoded data. An alternative is to use some basic encryption algorithm like theCaesar cipher, wh...
Ciphertext is encrypted information that contains the original plaintext information, but is stored in a way that humans can’t read, and even computers can’t if they lack the proper decryption key. Encryption keys are designed to be a one-off, unique algorithm used to encode and decode da...
Encryption was used to attempt to ensure secrecy in communications, such as those of spies, military leaders, and diplomats. An early example of the use of ciphers was the ‘Caesar Cipher’, in which each letter of the original text was replaced by another letter a fixed number of positions...
Nonces are a can of worms. No, really, one of the motivations for several CAESAR entries was to design an authenticated encryption scheme, preferably based on a stream cipher, that is resistant to nonce reuse. (Reusing a nonce with AES-CTR, for example, destroys the confidentiality of your...
Unencrypted data is also known as plaintext, and encrypted data is called ciphertext. Encryption algorithms, or ciphers, are used to encode and decode the data. An encryption algorithm is a mathematical method for encoding data according to a specific set of rules and logic. During the ...
2. Base64 decode the string. Actually, the code of the APK Protect-ed sample hides the call to Base64 decoding methods. It does not call the method directly but via Java reflection. The path for Base64 (android.util.Base64) is decoded from a XOR-encrypted string, and the method name...
