Answer (1 of 2): In simple terms SSL encrypted alert 21, describes that decryption got failed. It is defined as: "Decryption of a TLSCiphertext record is decrypted in an invalid way: either it was not an even multiple of the block length or its padding values, when checked, were not correct. This...The next step is responding to the CertificateRequest message produced by the server. If the TLS client trusted the server in the previous step, and it was sent CertificateRequest message, it will respond with a matching client certificate, if it has one. I am not aware of a TLS client implementation which would allow you to reach this step but ...

In TLS 1.2 handshake process server sends finished message and starts encrypting the data in the second round trip in step 5. Step #3: Change Cipher Spec, Client Finished, and Encrypted Application data.

Set up the MQ server: Start an MQ queue manager (our server) running in a Docker container which is set up for TLS encrypted messages. Secure an application: Edit some sample code to enable it to send encrypted messages to the queue manager. Step 1. Create TLS objects. We need to create a server key and certificate.Aug 05, 2015 · An SSL-3.0 handshake would explain the "alert" message, but it would certainly not be encrypted. (SSL-3.0 and TLS-1.0 are very similar, but have a few differences, one of them being the client behaviour when having been requested a certificate but being unable to provide one.) Both SSL and TLS protect data privacy through data-in-motion encryption, provide server-side and (optionally) client-side encryption of the communication channel, and help ensure message integrity. POP, IMAP and SMTP traffic are transmitted over designated ports. By default, IMAP uses port 143, POP uses port 110, and SMTP uses port 25.
