Crypto++ (also known as CryptoPP, libcrypto++, and libcryptopp) is a free and open source C++ class library of cryptographic algorithms and schemes written by Wei Dai. Crypto++ has been widely used in academia, student projects, open source and non-commercial projects, as well as businesses. Released in 1995, the library fully supports 32-bit and 64-bit architectures for many major operating systems and platforms, including Android (using STLport), Apple (Mac OS X and iOS), BSD, Cygwin, IBM AIX and S/390, Linux, MinGW, Solaris, Windows, Windows Phone and Windows RT. The project also supports compilation under C++03 and C++11, a variety of compilers and IDEs, including Borland Turbo C++, Borland C++ Builder, Clang, CodeWarrior Pro, GCC (including Apple's GCC), Intel C++ Compiler (ICC), Microsoft Visual C/C++, and Sun Studio.
Crypto++ ordinarily provides complete cryptographic implementations, and often includes less popular, less frequently-used schemes. For example, Camellia is an ISO/NESSIE/IETF-approved block cipher roughly equivalent to AES, and Whirlpool is an ISO/NESSIE/IETF-approved hash function roughly equivalent to SHA; both are included in the library.
Crypto1 is a proprietary encryption algorithm created by NXP Semiconductors specifically for Mifare RFID tags, including Oyster card, CharlieCard and OV-chipkaart.
Recent cryptographic research has shown that, "the security of this cipher is ... close to zero". Crypto1 is a stream cipher very similar in its structure to its successor, Hitag2. Crypto1 consists of
It can operate as an NLFSR and as an LFSR, depending on its input parameters. Outputs of one or both linear and nonlinear functions can be fed back into the cipher state or used as its output filters. The usual operation of Crypto1 and Hitag2 ciphers uses nonlinear feedback only during the initialization/authentication stage, switching to operation as LFSR with a nonlinear output filter for encrypting the tag's communications in both directions.
Offshore may refer to:
Offshore (1979) is a novel by Penelope Fitzgerald. It won the Booker Prize for that year. It recalls her time spent on boats on the Thames in Battersea. The novel explores the liminality of people who do not belong to the land or the sea, but are somewhere in between. The epigraph, "che mena il vento, e che batte la pioggia, e che s'incontran con si aspre lingue" ("whom the wind drives, or whom the rain beats, or those who clash with such bitter tongues") comes from Canto XI of Dante's Inferno.

"Offshore", when used relative to hydrocarbons, refers to an oil, natural gas or condensate field that is under the sea, or to activities or operations carried out in relation to such a field. There are various types of platform used in the development of offshore oil and gas fields, and subsea facilities.
Offshore exploration is performed with floating drilling units.
Exchange may refer to:
Exchange is a split album by the ska punk band Against All Authority and the punk rock band, The Criminals. It was first released in 1999 on Sub City Records.
