=head1 SYNOPSIS
int BN_hex2bn(BIGNUM **a, const char *str);
int BN_dec2bn(BIGNUM **a, const char *str);
- int BN_print_fp(FILE *fp, BIGNUM *a);
int BN_print(BIO *fp, const BIGNUM *a);
+ int BN_print_fp(FILE *fp, const BIGNUM *a);
int BN_bn2mpi(const BIGNUM *a, unsigned char *to);
BIGNUM *BN_mpi2bn(unsigned char *s, int len, BIGNUM *ret);
BN_bn2hex() and BN_bn2dec() return printable strings containing the
hexadecimal and decimal encoding of B<a> respectively. For negative
numbers, the string is prefaced with a leading '-'. The string must be
-Free()d later.
+freed later using OPENSSL_free().
BN_hex2bn() converts the string B<str> containing a hexadecimal number
to a B<BIGNUM> and stores it in **B<bn>. If *B<bn> is NULL, a new
length in hexadecimal digits. If the string starts with '-', the
number is negative. BN_dec2bn() is the same using the decimal system.
-BN_print_fp() and BN_print() write the hexadecimal encoding of B<a>,
-with a leading '-' for negative numbers, to the B<FILE> or B<BIO>

BN_bn2mpi() and BN_mpi2bn() convert B<BIGNUM>s from and to a format

+that consists of the number's length in bytes represented as a 4-byte

the most significant bit signals a negative number (the representation
of numbers with the MSB set is prefixed with null byte).

BN_mpi2bn() converts the B<len> bytes long representation at B<s> to

=head1 RETURN VALUES
BN_bn2mpi() returns the length of the representation. BN_mpi2bn()
returns the B<BIGNUM>, and NULL on error.
-The error codes can be obtained by ERR_get_error(3).
+The error codes can be obtained by L<ERR_get_error(3)|ERR_get_error(3)>.
