=head1 SYNOPSIS
int BN_bn2lebinpad(const BIGNUM *a, unsigned char *to, int tolen);
BIGNUM *BN_lebin2bn(const unsigned char *s, int len, BIGNUM *ret);
+ int BN_bn2nativepad(const BIGNUM *a, unsigned char *to, int tolen);
+ BIGNUM *BN_native2bn(const unsigned char *s, int len, BIGNUM *ret);

char *BN_bn2hex(const BIGNUM *a);
char *BN_bn2dec(const BIGNUM *a);
int BN_hex2bn(BIGNUM **a, const char *str);
BN_bn2binpad() also converts the absolute value of B<a> into big-endian form
and stores it at B<to>. B<tolen> indicates the length of the output buffer
-B<to>. The result is padded with zeroes if necessary. If B<tolen> is less than
+B<to>. The result is padded with zeros if necessary. If B<tolen> is less than
BN_num_bytes(B<a>) an error is returned.
BN_bin2bn() converts the positive integer in big-endian form of length
B<len> at B<s> into a B<BIGNUM> and places it in B<ret>. If B<ret> is
NULL, a new B<BIGNUM> is created.
-BN_bn2lebinpad() and BN_bin2lbn() are identical to BN_bn2binpad() and
+BN_bn2lebinpad() and BN_lebin2bn() are identical to BN_bn2binpad() and
BN_bin2bn() except the buffer is in little-endian format.
+BN_bn2nativepad() and BN_native2bn() are identical to BN_bn2binpad() and
+BN_bin2bn() except the buffer is in native format, i.e. most significant
+byte first on big-endian platforms, and least significant byte first on
+little-endian platforms.
+
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
BN_hex2bn() takes as many characters as possible from the string B<str>,
including the leading character '-' which means negative, to form a valid
hexadecimal number representation and converts them to a B<BIGNUM> and
-stores it in **B<bn>. If *B<bn> is NULL, a new B<BIGNUM> is created. If
-B<bn> is NULL, it only computes the length of valid representation.
+stores it in **B<a>. If *B<a> is NULL, a new B<BIGNUM> is created. If
+B<a> is NULL, it only computes the length of valid representation.
A "negative zero" is converted to zero.
BN_dec2bn() is the same using the decimal system.
buffer is too small.
BN_bn2hex() and BN_bn2dec() return a null-terminated string, or NULL
-on error. BN_hex2bn() and BN_dec2bn() return the the length of valid
-representation in hexadecimal or decimal digits, and 0 on error, in which
+on error. BN_hex2bn() and BN_dec2bn() return the number of characters
+used in parsing, or 0 on error, in which
case no new B<BIGNUM> will be created.
BN_print_fp() and BN_print() return 1 on success, 0 on write errors.
