How do I access the member `top` of a BIGNUM in OpenSSL 1.1.x?

QUESTION

How do I access the member `top` of a BIGNUM in OpenSSL 1.1.x?

Asked 2021-Sep-11 at 22:14

I'm currently trying to port an old C++ project over from OpenSSL 1.0.2 to OpenSSL 1.1.1. It's worth noting that this is not my code, but from an open source project, and I can't tell exactly what this part is supposed to do. One file uses this piece of code (simplified for this post):

The full example you linked, copies out the bits from a BIGNUM (for the RSA d exponent) into a different structure. It does not only access d->top (which is the number of used chunks), but also d->d (the pointer to the actual chunks) as the source of the memcpy in the next line.

The canonical way to copy out the bits of a BIGNUM is bn2bin.

As for your specific questions:

Generally speaking, no, as its semantics refer to the internal representation. However, you can easily compute the required size from the BIGNUMs number of bits, which you already have access to.
The number of chunks used to store the BIGNUM
By exporting the function into an appropriately sized target buffer using an export function.
