[jira] [Commented] (GUACAMOLE-350) Can't handle ssh key bigger than 4096 lengh

["Nick Couchman (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/GUACAMOLE-350?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16307570#comment-16307570 ] 

Nick Couchman commented on GUACAMOLE-350:
-----------------------------------------

Is there some sort of fixed/safe overhead on the instructions that would carry the SSH key that could be used to calculate a safe maximum value that could be used in the database without causing problems?  Or is bumping up the max instruction length really the only practical way around this?

> Because of guacamole_connection_parameter/parameter_value site set to 4096, keys bigger than 1024 bits can't be used.
> Update to 8192 could be enough (keys bigger than 10240 bits).
> Needs :
> . Database creation : change parameter_value from 4096 to 8192 (incubator-guacamole-client/extensions/guacamole-auth-jdbc/modules/guacamole-auth-jdbc-mysql/schema/001-create-schema.sql) + (incubator-guacamole-client/extensions/guacamole-auth-jdbc/modules/guacamole-auth-jdbc-postgresql/schema/001-create-schema.sql)
> . Mysql Database upgrade : ALTER TABLE guacamole_connection_parameter MODIFY parameter_value VARCHAR(8192);
> . don't know for postgresql
> Regards,
