TLS Ciphers Changes on Feb. 12th, 2024 8.30pm-9.00pm

The cypher suites in the TLS connection are adapted to the current industry security standard. Only the following cypher suites are authorised for TLS communication to the Swisscom Trust Service systems:



ECDHE-ECDSA-AES256-GCM-SHA384

ECDHE-RSA-AES256-GCM-SHA384

ECDHE-ECDSA-AES128-GCM-SHA256

ECDHE-RSA-AES128-GCM-SHA256

DHE-RSA-AES256-GCM-SHA384

DHE-RSA-AES128-GCM-SHA256




This means that connection calls that rely exclusively on ECDHE-RSA-CHACHA20-POLY1305, for example, will soon be rejected. Our protocols do not indicate that our clients are configured exclusively for these insecure cyphersuites, so we do not expect any restrictions in communication.
