Hi Billy Brumley,
I am trying to update the function eay_bn2v() in the racoon2 code. Please check the function in the below link
https://android.googlesource.com/platform/external/ipsec-tools/+/051f86dfca525c160855397f7b6a4fb5ef8df2b5/src/racoon/crypto_openssl.c
But I found one more source of racoon2 where they are using BN_num_bytes(bn) instead of bn->top * BN_BYTES
in eay_bn2v() which I will try to use. Please find the same in the below link
https://github.com/zoulasc/racoon2/blob/master/iked/crypto_openssl.c
Thanks and Regards,
Sunil

Since the structure is opaque, I can't imagine _really_ needing access to ->top since that is a BIGNUM-internal concept.
Can you give a MWE for what you are trying to achieve?
Cheers,

I guess that "minimal working example" is the correct choice from the gazillions of possible meanings of "MWE"? ?
