In this work, we propose a new block cipher that is called Nahrainfish, which we believe that it offers the required security level for present and foreseeable future without a big sacrifice in ...

The cryptographic algorithm QARMA is a family of lightweight tweakable block ciphers targeted at applications such as memory encryption and construction of keyed hash functions. Utilizing lightweight ...

According to commentary from @CryptoMuseum, recent live demonstrations of early cryptography cipher machines have highlighted the historical evolution of secure communication, which directly informs ...

Quantum computers may crack RSA encryption with fewer qubits than expected by Bob Yirka, Phys.org edited by Lisa Lock, reviewed by Robert Egan Editors' notes ...

Quantum Computing Could Break Bitcoin-Like Encryption Far Easier Than Intially Thought, Google Researcher Says A new research paper from a Google researcher slashed the estimated quantum resources ...

Quantum computing can break Bitcoin’s encryption using Shor’s algorithm, threatening wallets and transactions within 5-7 years. The crypto industry must urgently adopt post-quantum cryptography to ...

使用加密库（如Java的javax.crypto或第三方库如Bouncy Castle）实现解密。 将解密后的明文信息存储在内存中，避免直接写入磁盘。 示例代码（Java）： java import javax.crypto.Cipher; import javax.crypto.spec.SecretKeySpec; import java.util.; public class ...

Encryption can be as simple as the 2,000-year-old Caesar cipher, where you shift each letter by a certain number to encode a message, or as complex as modern cryptographic mathematical models such ...
