Report correct unencrypted length #126

Open nevelis opened 3 years ago

nevelis commented 3 years ago

COSE_Encrypt_GetContent() returns a valid pointer to the content, but the length parameter is set to 0.

The reason for this is because cbOut is set to the correct value, but is then used as the remaining bytes in the EVP functions and gets set to 0.

This PR sets the output parameter to the correct value, so we can use the payload safely.
