MySQL DAM and $sslset()

[Reg Paling]

Hi all,

I am trying to connect from my Omnis dev kit to a MySQL database on a 
remote server.  (It is a WordPress database).

I can connect to another non-WordPress MySQL database on a totally 
different remote site, so I know the DAM and network etc is working.

I can connect OK from MySQLWorkbench.app on my Mac, using a "Standard 
(TCP/IP)" connection with just a username and password that were 
supplied to me.
In MySQLWorkbench, executing "SHOW STATUS LIKE 'Ssl_cipher';" gives
     Ssl_cipher    TLS_AES_256_GCM_SHA384
... which I take as an indication that MySQLWorkbench appears to have 
bumped up the connection to a secure connection even though I did not 
ask for that.  Would that be correct?

When I try to connect from Omnis, I get error 2026    "SSL connection 
error: unknown error number"

I am guessing I have to supply some certificate files to support an SLL 
connection from Omnis.   From what I have read, if I supply just a key 
and certificate to support encryption from my end, I don't need to 
install any certificate from the server.  The fact that I can connect 
from MySQLWorkbench proves I don't need any certificate from the server.

I gather I can use $sslset() to tell the DAM which certifcate file/s to 
use, but I don't know what the parameters mean:
 From the Omnis documentation:
SessObj.$sslset([cKey, cCert, cCA, cCAPath, cCipher]) is used for 
establishing a secure connection using SSL. It must be called before 
$logon(). cKey is the path name to the key file. cCert is the path name 
to the certificate file. cCa is the path name to the certificate 
authority file. cCAPath is the path name to a directory that contains 
trusted SSL CA certificates in pem format. cCipher is a list of 
permissible ciphers to use for SSL encryption. Any unused SSL parameters 
will be treated as NULL.

Can anyone please point me in the right direction?

Thanks,
Reg
