Hi all,

I am aware that there are tons of raw transactions that can be used for 
testing Segwit transaction constructors in BIP143 and also in the tests/ 
folder of the codebase somewhere.

However, I am having a hard time finding reproducible legacy transactions. 
This is usually for one of two reasons:

1) Important information for debugging the transaction signing such as the 
preimage or private key is missing.
2) The transactions were using OpenSSL to create the signatures, which 
results in them being non-deterministic and useless for tests. As opposed 
to using libsecp256k1.

So I am just wondering if anybody knows if there is a place where I can 
find a bunch of raw legacy transactions, together with private keys, to 
test my software with.

-Ali

Well, you might use core itself to create a bunch of private keys and
legacy transactions.
That will imply you trust core as a golden model for your software, but
since almost everyone in the network assumes to be bug compatible with
core, I don't see a problem.

Or am I missing something and being too simplistic?

I don't think that its a good idea to rely on my own generated Core 
transactions, though. Not because I don't trust Core as having a correct 
transaction implementation, but because the transactions are still 
ultimately generated by me so that they are not covering all the edge cases.
