WebMost current implementations of cryptographically-protected electronic mail protect only the body of the message, which leaves significant room for attacks against otherwise-protected messages. For example, lack of header protection allows an attacker to substitute the message subject and/or author. ¶ Symmetric-key cryptography Symmetric-key cryptography refers to encryption methods in which both the sender and receiver share the same key (or, less commonly, in which their keys are different, but related in an easily computable way). This was the only kind of encryption publicly known until June … 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 General Cryptography is widely used on the internet to help protect user-data and prevent … See more Prohibitions Cryptography has long been of interest to intelligence gathering and law enforcement agencies. … See more • Arbib, Jonathan; Dwyer, John (31 January 2011).
