unable to send file to AS2 server from AS2-LIB but works fine from Mendelson server about as2-lib HOT 4 CLOSED

The other server sent an invalid MDN, because no MIC is contained:

MIC IS NOT MATCHED, original mic: 'IpjGylckS2ovHgk995aA3SU2Jlw=, sha1' return mic: 'null' [<JavaAS2Client_phaxAS2Lib-17052018091234+0000-5617@788157159_CTS_AS2_ZZFDATST>]

do you have access to the other server logfiles?

from as2-lib.

Thanks for the quick response!

Unfortunately - no, since it is a FDA (US FDA) AS2 server. Is there some other information I may provide?

I just realized that the self signed certificate that we are using at our end (one containing the private key) is using SHA-1 while the certificate we received from FDA is using SHA-256. As you may have noticed, in the code I am using SHA-1 for the signature algorithm.

Could this cause the error?

Hi. Sorry for the delay. Was on vacation.
Imho the algorithm of the certificate hash is independent of the MIC algorithm you choose.
Are you sure, that the receiving system trusts your self-signed certificate?
