The Data Encryption Standard (DES / ˌ d iː ˌ iː ˈ ɛ s, d ɛ z /) is a symmetric-key algorithm for the encryption of digital data. Although its short key length of 56 bits makes it too insecure for modern applications, it has been highly influential in the advancement of cryptography .

The original version (ISO 646 IRV) differed from ASCII only in that code point 0x24, ASCII's dollar sign ($) was replaced by the international currency symbol (¤). The final 1991 version of the code ISO/IEC 646:1991 is also known as ITU T.50 , International Reference Alphabet or IRA, formerly International Alphabet No. 5 (IA5).
Signcryption is a relatively new cryptographic technique that is supposed to perform the functions of digital signature and encryption in a single logical step and can effectively decrease the computational costs and communication overheads in comparison with the traditional signature-then-encryption schemes.
RSA (Rivest–Shamir–Adleman) is a public-key cryptosystem, one of the oldest widely used for secure data transmission.The initialism "RSA" comes from the surnames of Ron Rivest, Adi Shamir and Leonard Adleman, who publicly described the algorithm in 1977.
