Hi there !
New comer on LEDE Project i installed it on my brand new Linksys WRT3200ACM... So cool 
My question is : can i use an ed25519 (521bits key long) like under Debian ? Is it possible to create one as well ?
Thx for yur return

LEDE disables ECDSA support in Dropbear to save space. 
The number of routers that have small amounts of flash are disappearing though, so I hope more "full" LEDE builds will prevail.
In the mean time you will have to ask for a dropbear package to be built with all support added. Similar to "wpad" and "wpad-mini".

...or simply build that package yourself, the build setting is exported as accessible config symbol.
Hi folks,
Thank you for yur help.
Maybe i'll try to buils such a package when i feel more comfortable with all that stuff...
Another alternative if you have adequate flash memory is to install the OpenSSH packages which do have support for ECDSA.
I found a mod of dropbear, but I don't know how to use it.
