Size of ssh-rsa exception #607

Open Beban9999 opened 3 months ago

Beban9999 commented 3 months ago

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

Is there a way to change acceptable key size?

Thanks in advance

Hi @Beban9999,

That is a limitation of the JDK version you are using, not JSch.

Thanks, Jeremy

Hi @norrisjeremy Thanks for the quick replay. I did not have this issue in the old JSch version.

Thanks

I built the package using Java 1.9

Hi @Beban9999,

It's not a JSch issue. Go search Google for the phrase Prime size must be multiple of 64, and can only range from 512 to 2048.

Thanks, Jeremy

Is this the problem of the JDK that I use to build the library or the JDK that I use in the application that is running it?

Hi @Beban9999,

It is an issue with the version of the JDK you are using to run you application.

Thanks, Jeremy
