Function Documentation

BIGNUM * CODEX_Ciphers::BIGNUM_xor (  BIGNUM *  r, const BIGNUM *  a, const BIGNUM *  b )

This functions computes the XOR of two BIGNUM%s. Parameters: r  The return value, if non-0. a  The first operand. b  The second operand. Returns: The XOR of a and b. If r is 0, a new pointer is returned. Note: The code was lifted from bn_gf2m.c in a later release of OpenSSL than was available during development of this package. This product includes software developed by the OpenSSL Project for use in the OpenSSL Toolkit (http://www.openssl.org/) Definition at line 24 of file BIGNUM_xor.cc. Referenced by CODEX_Ciphers::VarRSAPrivateKey::decrypt(), CODEX_Ciphers::VarRSAPublicKey::encrypt(), and CODEX_Ciphers::VarRSABlindPlainText::unblind().

BIGNUM * CODEX_Ciphers::jacobi (  const BIGNUM *  a, const BIGNUM *  n )

This function returns the Jacobi symbol (a|n). Returns: A new BIGNUM containing the result Definition at line 24 of file jacobi.cc. Referenced by CODEX_Ciphers::ElGamalPublicKey::encryptVals().
