.... Set up some character translations and predefined strings. \*(-- will
give an unbreakable dash, \*(PI will give pi, \*(L" will give a left
double quote, and \*(R" will give a right double quote. \*(C+ will
give a nicer C++. Capital omega is used to do unbreakable dashes and
therefore won't be available. \*(C` and \*(C' expand to `' in nroff,
nothing in troff, for use with C<>.

Escape single quotes in literal strings from groff's Unicode transform.
If the F register is >0, we'll generate index entries on stderr for
titles (.TH), headers (.SH), subsections (.SS), items (.Ip), and index
entries marked with X<> in POD. Of course, you'll have to process the
output yourself in some meaningful fashion.
Avoid warning from groff about undefined register 'F'.

Title "BN_BN2BIN 3ossl"
way too many mistakes in technical documents.
\fBBN_bn2binpad() also converts the absolute value of a into big-endian form and stores it at to. tolen indicates the length of the output buffer \fBto. The result is padded with zeros if necessary. If tolen is less than BN_num_bytes(a) an error is returned.
\fBBN_bin2bn() converts the positive integer in big-endian form of length \fBlen at s into a \s-1BIGNUM\s0 and places it in ret. If ret is \s-1NULL,\s0 a new \s-1BIGNUM\s0 is created.
\fBBN_bn2lebinpad() and BN_lebin2bn() are identical to BN_bn2binpad() and \fBBN_bin2bn() except the buffer is in little-endian format.
\fBBN_bn2nativepad() and BN_native2bn() are identical to BN_bn2binpad() and \fBBN_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.
\fBBN_bn2hex() and BN_bn2dec() return printable strings containing the hexadecimal and decimal encoding of a respectively. For negative numbers, the string is prefaced with a leading '-'. The string must be freed later using OPENSSL_free().
\fBBN_hex2bn() takes as many characters as possible from the string str, including the leading character '-' which means negative, to form a valid hexadecimal number representation and converts them to a \s-1BIGNUM\s0 and stores it in **a. If *a is \s-1NULL,\s0 a new \s-1BIGNUM\s0 is created. If \fBa is \s-1NULL,\s0 it only computes the length of valid representation. A \*(L"negative zero\*(R" is converted to zero. \fBBN_dec2bn() is the same using the decimal system.
\fBBN_print() and BN_print_fp() write the hexadecimal encoding of a, with a leading '-' for negative numbers, to the \s-1BIO\s0 or \s-1FILE\s0 \fBfp.
\fBBN_bn2mpi() and BN_mpi2bn() convert \s-1BIGNUM\s0s from and to a format that consists of the number's length in bytes represented as a 4-byte big-endian number, and the number itself in big-endian format, where the most significant bit signals a negative number (the representation of numbers with the \s-1MSB\s0 set is prefixed with null byte).
\fBBN_bn2mpi() stores the representation of a at to, where to must be large enough to hold the result. The size can be determined by calling BN_bn2mpi(a, \s-1NULL\s0).
\fBBN_mpi2bn() converts the len bytes long representation at s to a \s-1BIGNUM\s0 and stores it at ret, or in a newly allocated \s-1BIGNUM\s0 if ret is \s-1NULL.\s0
\fBBN_bn2binpad(), BN_bn2lebinpad(), and BN_bn2nativepad() return the number of bytes written or -1 if the supplied buffer is too small.
\fBBN_bn2hex() and BN_bn2dec() return a NUL-terminated string, or \s-1NULL\s0 on error. BN_hex2bn() and BN_dec2bn() return the number of characters used in parsing, or 0 on error, in which case no new \s-1BIGNUM\s0 will be created.
\fBBN_print_fp() and BN_print() return 1 on success, 0 on write errors.
\fBBN_bn2mpi() returns the length of the representation. BN_mpi2bn() returns the \s-1BIGNUM\s0, and \s-1NULL\s0 on error.
The error codes can be obtained by ERR_get_error\|(3).
