Crypto++ Library is a free C++ class library of cryptographic schemes. Other features include: * pseudo random number generators (PRNG): ANSI X9.17 appendix C, RandomPool * password based key derivation functions: PBKDF1 and PBKDF2 from PKCS #5, PBKDF from PKCS #12 appendix B * Shamir's secret sharing scheme and Rabin's information dispersal algorithm (IDA) * fast multi-precision integer (bignum) and polynomial operations * finite field arithmetics, including GF(p) and GF(2^n) * prime number generation and verification * useful non-cryptographic algorithms o DEFLATE (RFC 1951) compression/decompression with gzip (RFC 1952) and zlib (RFC 1950) format support o hex, base-32, and base-64 coding/decoding o 32-bit CRC and Adler32 checksum * class wrappers for these operating system features (optional): o high resolution timers on Windows, Unix, and Mac OS o Berkeley and Windows style sockets o Windows named pipes o /dev/random, /dev/urandom, /dev/srandom o Microsoft's CryptGenRandom on Windows * A high level interface for most of the above, using a filter/pipeline metaphor * benchmarks and validation testing * x86, x86-64 (x64), MMX, and SSE2 assembly code for the most commonly used algorithms, with run-time CPU feature detection and code selection o supports GCC-style and MSVC-style inline assembly, and MASM for x64 * certain versions are available in FIPS 140-2 validated form
