We added a new JNDI to the FtpAdapter in Oracle SOA Suite 12.2.1.0.0, and upon execution of the SOA composite, received the error "blowfish-cbc is not supported".
Blowfish is a cipher, and this generally should be configured within the adapter itself.
Oracle Doc ID 2294667.1 states that patch 26561747 is available to resolve this, but this patch is only available for 12.2.1.2.0 and 12.2.1.3.0. The same note describes adding a properties to the composite.
Here are snippets of what can appear in the SOA diagnostic log file:

Adapter internal error.
The adapter has become unstable. This could be because of incorrect parameters supplied to the adapter. The parameter: {0} had value: {1}

The solution is simply to add the cipher to the adapter.
- Log in to the WebLogic Server Administration Console.
- Click on Lock & Edit.
- Click on Deployments.
- Click on FtpAdapter.
- Click on Configuration.
- Click on Outbound Connection Pools.
- Expand javax.resource.cci.ConnectionFactory.
- Click on the outbound connection pool for the FTP resource adapter.
- In the PreferredCipherSuite property, add "aes128-cbc" (see screenshot below)
- Save.
- Navigate to Deployments.
- Select the checkbox beside FtpAdapter.
- Click on Update.
- Select Update this application in place with new deployment plan changes.
- Click Next.
- Click Finish.
- Activate changes.
- Restart the entire domain (including AdminServer).
