The 'strlen' function is only useable on a C-style string. The signature cannot
be a C-style string because it is arbitrary binary data.

Hi,
As explained in the initial email we were able to resolve the
"RSA_verify:wrong signature length" by generating the signature in two steps as
explained below (which generates 128 byte signature):
openssl dgst -md5 -binary -out signmd.bin input.txt
openssl rsautl -encrypt -inkey rsap
