2361271 - SFTP Connector Error in Boomi: Session.connect: java.security.InvalidAlgorithmParameterException: Prime size must be multiple of 64, and can only range from 512 to 1024 (inclusive)

When you are checking the Boomi process log you can see that it fails due to SFTP connector issue with below error:

Session.connect: java.security.InvalidAlgorithmParameterException: Prime size must be multiple of 64, and can only range from 512 to 2048 (inclusive)

Boomi

• For Java version lower than 8, there is a prime limitation of 1024 which is why this error is being received when a host certificate of larger size is being passed
• This is a Java limitation with prime size, not key length
• Boomi supports the industry standard of 2048 key length, but prime is different 

Check your Java version:

1. If the Java version is lower than 8, upgrade to Java version 8 because the bug has been fixed on this version. 
2. Restart the atom server after upgrade and test the process execution again.
