Mad Bill Cipher Novels & Stories

“These codes you see here are called ‘Circolo’.” He then stood up and walked to where I sat, opposite him. He then stood beside me, his hand resting on the table for balance. “This is a complex code that our empire's communication relies on and is known to only trusted members.” I nodded as I listened attentively. "Circolo uses a combination of Caesar cipher and Vigenère cipher. The key changes every 72 hours." He paused to let what he had said sink in. As Don Antonio spoke, my mind wandered to the secret interactions that I’d observed between Lorenzo and Sophia.

10-48-32-24-30-38-18-30-28 I shook my head, “Not alphanumeric substitution; Rot-1, Rot-13, Base 8 doesn’t make sense; Polybius Square has no eight… Obviously, this code involves Mathematics because the caller used the words ‘figure out’ and ‘find the answer’ which are commonly asked in the subject.” I handed him the strip of paper and asked, “Do you have any insight, Major?” “You’re… asking me?” “I’m sure I made it quite obvious.” He chuckled, shaking his head. I stared at him in puzzlement, but we eventually returned to the serious matter at hand.

“They….they were Silas’s mercenaries. He’s reaching out to human extremist groups.” “He’s desperate,” Faith said, helping him up. “But he just made a mistake. He showed me how they’re communicating.” Back at the estate, Faith sat in front of her computer array. She had pulled the data from the melted rifles and traced the signal back to a hidden server in the South. “They’re using a blood-coded encryption," Leo said, leaning over her shoulder. “I can't break it, Faith. It requires a physical sample of the sender's DNA to unlock the messages.”

He quickly extracted all the data he could from Clarice's computer, including her encrypted private album. It contained countless images of the decadent lifestyle she had led when she was studying abroad. She was notorious for being a mistress and loved being part of large parties. There was even a recorded audio of her bribing a professor. “Maybe soon you will know that what goes around, comes around.” Liam smirked before saving all of the documents he had accessed. It was well into midnight by then. Clarice was enjoying a face mask session while scrolling through social media when a strange message popped up on her computer.

—a stereotype I was all too tired of hearing. I flipped open the screen. The codes I’d spent all morning perfecting glowed against the dark interface. “The bypass is ready, Sirs,” I whispered. Internally, I was screaming. God, I should have asked for a bulletproof vest instead of a red dress! “This is the decryption code you requested, Sir. I managed to shatter the 256-bit encryption layer. It’s a masterpiece—a rare recursive encryption capable of breaching secured firewalls in seconds.” I turned the laptop toward the client, unable to hide a small, proud smile.

“The name of the person who ordered the hit on me. The name of the one responsible for putting me in this fucking chair and killing my daughter.” The silence in the room turned weaponized. A few brows rose. Marcello’s smirk faltered. Dante’s fingers finally stopped twitching. “I haven’t decrypted it yet,” I said slowly, letting the tension bleed from every syllable. “It’s encoded. Old-world cipher. But I’ve tasked my best men. We’ll break it within the next forty-eight hours.” I looked at each of them in turn. “But I didn’t come here to ask for help.” I reached into the briefcase in front of me and tossed a set of sealed envelopes onto the table — thick, ivory parchment with each of their na

"A polyalphabetic cipher." "Worth a try?" Shawn responded as Catherine tapped the tablet and scrolled for something more. Catherine murmured under her breath, clearly relieved to have finally accomplished something. "Shawn, you can start substituting the letters as I read this…" "OK." "The Vigenère cipher is probably the best-known example of a polyalphabetic cipher, though it is a simplified special case. The idea was to encipher the first letter of the message using the first shifted alphabet, so A became B, B became C, etc. The second letter of the message was enciphered using the second shifted alphabet, etc."

MI5 and MI6 feared that girls like guys with cars refer to a car bomb and reference to parties and weddings to the attack. I noticed the contrast between the one-time cypher that Nelson and I had used to contact each other and the emails sent and received by Z. The latter would have been unbreakable if they had used a unique key. But, as in the case of the Liquid Bombers, they had used the same key again and again.

Solomon went to look for Blair at Fowler Enterprise early in the morning. “Everything I could find out about Mable is here.” Blair flipped open the file he handed over, which contained only a few lines of records. “That’s all?” Solomon shrugged helplessly. “Mable’s information has probably been encrypted. Other than her basic information, nothing else could be found.” ‘Mable’s information was encrypted?’ Blair frowned. This was something he had not expected. Normal people would not do that. Blair stared at the document in his hand. A cold light flashed across his dark eyes.

He leaned back, the blue light of the monitor casting sharp, hollow shadows across his face. "This isn't standard Council encryption, Fenn," Jax muttered, rubbing his eyes. "This is military-grade, multi-layered 'ghost' coding. It’s designed to self-destruct if I try to force the door. One wrong keystroke and the whole drive turns into a paperweight."
