WebDefinition. Cryptography provides for secure communication in the presence of malicious third-parties—known as adversaries. Encryption uses an algorithm and a key to transform an input (i.e., plaintext) into an encrypted output (i.e., ciphertext). A given algorithm will always transform the same plaintext into the same ciphertext if the same ... Key cryptographic techniques that enable cryptocurrencies and cryptoeconomics include, but are not limited to: cryptographic keys, cryptographic hash functions, asymmetric (public key) encryption, Multi-Factor Authentication (MFA), End-to-End Encryption (E2EE), and Zero Knowledge Proofs (ZKP). See more Cryptography, or cryptology (from Ancient Greek: κρυπτός, romanized: kryptós "hidden, secret"; and γράφειν graphein, "to write", or -λογία -logia, "study", respectively ), is the practice and study of techniques for secure communication See more Before the modern era, cryptography focused on message confidentiality (i.e., encryption)—conversion of messages from a comprehensible … See more Symmetric-key cryptography Symmetric-key cryptography refers to encryption methods in which both the sender and receiver share the same key (or, less commonly, … See more Prohibitions Cryptography has long been of interest to intelligence gathering and law enforcement agencies.
