SFTP - Prime size must be multiple of 64, and can only range from 512 to 1024 (inclusive)

Question

I am getting an error in the qie log "Prime size must be multiple of 64, and can only range from 512 to 1024 (inclusive)" when connected to a SFTP site

Answer 1

This error is because the SFTP site is using an SSL Key that is length 2048. Java 7 supports keys up to 1024 in length. To fix this upgrade to Java 8 or higher.
