WebJun 11, 2012 · Cryptography is a science that applies complex mathematics and logic to design strong encryption methods. Achieving strong encryption, the hiding of data’s meaning, also requires intuitive leaps that allow creative application of known or new methods. So cryptography is also an art. Early cryptography WebApr 14, 2024 · Full-entropy bitstrings are important for cryptographic applications because they have ideal randomness properties and may be used for any cryptographic purpose. Due to the difficulty of generating and testing full-entropy bitstrings, the NIST SP 800-90 series assumes that a bitstring has full entropy if the amount of entropy per bit is at ... initialize self python
