ciphers and TLS

[sjm2000]

hi all

We are trying to make service call out to another domain (outbound connection).

How do we find out the ciphers and TLS versions supported by apigee for outbound calls.

We use opdk 4.50

By default the latest versions are supported. You can configure older versions as well in the message processor.

Great to know the latest versions are supported.

However, how do we know the exact TLS versions supported?

Also if possible the ciphers supported.

We are currently receiving http 503 (service unavailable)

Check first what the backend is supported, the same you can configure in message processor or target server configuration.

This page documents configuring TLS on the message processor and lists supported ciphers.
