NAME
BN_set_bit, BN_clear_bit, BN_is_bit_set, BN_mask_bits, BN_lshift, BN_lshift1, BN_rshift, BN_rshift1 - bit operations on BIGNUMs SYNOPSIS
#include <openssl/bn.h> int BN_set_bit(BIGNUM *a, int n); int BN_clear_bit(BIGNUM *a, int n); int BN_is_bit_set(const BIGNUM *a, int n); int BN_mask_bits(BIGNUM *a, int n); int BN_lshift(BIGNUM *r, const BIGNUM *a, int n); int BN_lshift1(BIGNUM *r, BIGNUM *a); int BN_rshift(BIGNUM *r, BIGNUM *a, int n); int BN_rshift1(BIGNUM *r, BIGNUM *a); DESCRIPTION
BN_set_bit() sets bit n in a to 1 ("a|=(1<<n)"). The number is expanded if necessary. BN_clear_bit() sets bit n in a to 0 ("a&=~(1<<n)"). An error occurs if a is shorter than n bits. BN_is_bit_set() tests if bit n in a is set. BN_mask_bits() truncates a to an n bit number ("a&=~((~0)>>n)"). An error occurs if a already is shorter than n bits. BN_lshift() shifts a left by n bits and places the result in r ("r=a*2^n"). BN_lshift1() shifts a left by one and places the result in r ("r=2*a"). BN_rshift() shifts a right by n bits and places the result in r ("r=a/2^n"). BN_rshift1() shifts a right by one and places the result in r ("r=a/2"). For the shift functions, r and a may be the same variable. RETURN VALUES
BN_is_bit_set() returns 1 if the bit is set, 0 otherwise. All other functions return 1 for success, 0 on error. The error codes can be obtained by ERR_get_error(3). SEE ALSO
