WebICSF supports two main types of cryptographic processes: Symmetric, or secret key, algorithms, in which the same key value is used in both the encryption and decryption calculations. Asymmetric, or public key, algorithms, in which a different key is used in the decryption calculation than was used in the encryption calculation. 3Modern cryptography Toggle Modern cryptography subsection 3.1Symmetric-key cryptography 3.2Public-key cryptography 3.3Cryptographic hash functions 3.4Cryptanalysis 3.5Cryptographic primitives 3.6Cryptosystems 3.7Lightweight cryptography 4Applications Toggle Applications subsection … 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 form into an incomprehensible one and back again at the other end, rendering it unreadable by interceptors or … See more General Cryptography is widely used on the internet to help protect user-data and prevent eavesdropping.
