bn_mul_recursive(3)  BIGNUM library internal functions

This page documents the internal functions used by the OpenSSL BIGNUM implementation. They are described here to facilitate debugging and extending the library. They are not to be used by applications... 
BN_mul_word(3)  arithmetic functions on BIGNUMs with integers

These functions perform arithmetic operations on BIGNUMs with unsigned integers. They are much more efficient than the normal BIGNUM arithmetic operations. BN_add_word() adds w to a ("a+=w"). BN_sub...

BN_new(3)  allocate and free BIGNUMs

BN_new() allocated and initializes a BIGNUM structure. BN_init() initializes an existing uninitialized BIGNUM. BN_clear() is used to destroy sensitive data such as keys when they are no longer needed.... 
BN_num_bits(3)  get BIGNUM size

These functions return the size of a BIGNUM in bytes or bits, and the size of an unsigned integer in bits. BN_num_bytes() is a macro. 
BN_num_bits_word(3)  get BIGNUM size

These functions return the size of a BIGNUM in bytes or bits, and the size of an unsigned integer in bits. BN_num_bytes() is a macro. 
BN_num_bytes(3)  get BIGNUM size

These functions return the size of a BIGNUM in bytes or bits, and the size of an unsigned integer in bits. BN_num_bytes() is a macro. 
BN_one(3)  BIGNUM assignment operations

BN_zero(), BN_one() and BN_set_word() set a to the values 0, 1 and w respectively. BN_zero() and BN_one() are macros. BN_value_one() returns a BIGNUM constant of value 1. This constant is useful for u... 
BN_print(3)  format conversions

BN_bn2bin() converts the absolute value of a into bigendian form and stores it at to. to must point to BN_num_bytes(a) bytes of memory. BN_bin2bn() converts the positive integer in bigendian form of ...

BN_print_fp(3)  format conversions

BN_bn2bin() converts the absolute value of a into bigendian form and stores it at to. to must point to BN_num_bytes(a) bytes of memory. BN_bin2bn() converts the positive integer in bigendian form of ... 
BN_pseudo_rand(3)  generate pseudorandom number

BN_rand() generates a cryptographically strong pseudorandom number of bits bits in length and stores it in rnd. If top is 1, the most significant bit of the random number can be zero. If top is 0, i...
