<Cannot register because the algorithm of this key is not supported.> is displayed when you
try to register a key pair file.
Cause You are trying to register a key pair file which uses the DSA algorithm.
Remedy Register a key pair file which uses the RSA algorithm.
You cannot use encrypted SSL communication for IPP printing, email/I-fax, the Remote UI,
MEAP functions via a web browser, and device information delivery, or confirm Department
IDs and passwords even after you have turned SSL on.
Cause 1 The generated key pair or server certificate is corrupted.
Remedy After erasing the key pair you are using (see "Editing Key Pairs and Server
Certificates," on p. 3-32), generate a key pair and server certificate (see
"Generating a Key Pair and Server Certificate," on p. 3-28).
Cause 2 The preinstalled default key pair or server certificate is corrupted.
Remedy After erasing the key pair you are using (see "Editing Key Pairs and Server
Certificates," on p. 3-32), generate a key pair and server certificate (see
"Generating a Key Pair and Server Certificate," on p. 3-28).
Cause 3 The registered key pair file or server certificate file is corrupted.
Remedy After erasing the key pair you are using (see "Editing Key Pairs and Server
Certificates," on p. 3-32), using the Remote UI, install the key pair file and
server certificate file created on your computer (See the Remote UI Guide.).
Then, register the installed files on the control panel of the machine (see
"Registering a Key Pair File and Server Certificate File Installed from a
Computer," on p. 3-31).
NOTE
For instructions on how to confirm whether the key pair you are using is corrupted, see
"Editing Key Pairs and Server Certificates," on p. 3-32.
