Tor exit relays can eavesdrop on communications if encryption to the server is disabled. For a comprehensive comparison of instant messengers, see here. It is recommended to review the Do not Mix Anonymity Modes section in conjunction with this entry. See Post-Quantum Cryptography (PQCrypto).
It is estimated that within 10 to 15 years, Quantum Computers will break today's common asymmetric public-key cryptography algorithms used for web encryption (https), e-mail encryption (GnuPG.), SSH and other purposes.
