Previously, a loop in pkcs7_get_signers_info_set was not
getting covered by tests. This was because when there are
two or less signers, the loop will not execute.
Therefore, add new data files for another signer and use
three signers to generate a new pkcs7 DER file. Add a test
case to make sure that verification is still successfula and
use the test script to create ASN1 errors throoughout the
stucture:
./generate_pkcs7_tests.py ../data_files/pkcs7_data_3_signed.der
This results in the loop being executed.
