If you want to use a key and certificate that you generate yourself, generate the key and certificate before performing the procedure below. Generating the Key and Certificate for Network Communication If you want to use a key and certificate that you acquire from a certification authority (CA), register the key and certificate before performing the procedure below. Registering a Key and Certificate If you set <Format Encryption Method to FIPS 140-2> to <On>,you can make the TLS communication encryption method comply with the United States government-approved FIPS (Federal Information Processing Standards) 140-2. <Format Encryption Method to FIPS 140-2> If <Format Encryption Method to FIPS 140-2> is set to <On>, an error will occur when you try to specify a certificate for TLS that uses an algorithm not recognized by FIPS (lower than RSA2048bit). A communication error will occur if you set <Format Encryption Method to FIPS 140-2> to <On>, and send to a remote party that does not support FIPS-recognized encryption algorithms. If <Format Encryption Method to FIPS 140-2> is set to <On>, <CHACHA20- POLY1305> and <X25519> switch to <Off>. If <CHACHA20- POLY1305> or <X25519> is set to <On>, <Format Encryption Method to FIPS 140-2> switches to <Off>. |
