Hello everyone
I apologize in advance because my English is not the best
I'm experiencing a problem with stunnel:
On the server I'm running a current version [.] stunnel 5.56 on x86_64-pc-linux-gnu platform Compiled / running with OpenSSL 1.1.1d 10 Sep 2019
And on the client an old version [.] stunnel 5.39 on x86_64-pc-linux-gnu platform Compiled with OpenSSL 1.1.0c 10 Nov 2016
The case is that I am having an error in the server log as shown below:
SSL_accept: ../ssl/record/ssl3_record.c:677: error: 1408F119: SSL routines: ssl3_get_record: decryption failed or bad record mac
I did the test by updating the client to the same version and everything works, the question I have is whether there is really an incompatibility between the versions (be it the stunnel or the openssl).
Does anyone know how to confirm me if this is real?
Thanks
Vaz
