ssh: Bump the minimum key size to 768 bits (1.02 KB, patch)
2013-08-07 19:40 UTC, Stef Walter 		committed Details | Review

Description Aruna Sankaranarayanan 2013-08-06 12:57:56 UTC 
*Steps to reproduce*
File->New->Secure Shell Key.

Click Advanced key options -> Decrease the key strength(bits) thing to 512 bytes

You're prompted with the message - "Key must at least be 768 bits".


*Expected behaviour*

You shouldn't be able to decrease the key size below 768 bits.

ssh: Bump the minimum key size to 768 bits

Does this patch fix the issue for you, and work for both RSA and DSA?
Comment 2 Aruna Sankaranarayanan 2013-08-13 08:08:36 UTC 
Hi Stef, thanks for the patch. :)

The patch works perfectly when the key-type is RSA. 

When the key type is DSA, irrespective of the key size I choose, the key size freezes to 1024. Further, when I click the "Just Create Key" button, I get this error message as a prompt and on the commandline:

"Couldn't generate Secure Shell key

Generating public/private dsa key pair.
(null) already exists.
Overwrite (y/n)?"
